Cisco Systems has lately become aggressive in promoting applications of the IP network infrastructure equipment that the company has traditionally sold. Cisco CallManager--the subject of Cisco CallManager Fundamentals--is essentially an IP-based Public Branch Exchange (PBX) that enables companies to carry their voice and data traffic on a single network infrastructure. This book explains how CallManager (originally developed by Selsius Systems) goes about providing call-control services to IP telephony devices and performing reliably as a corporate telephone switch, and offers insight into how the product may evolve. The volume provides systems architects, engineers, and implementation technicians with the details they need to build strong CallManager systems.

Written by members of the CallManager development team and extensively edited for accuracy, Cisco CallManager Fundamentals uses prose and remarkably clear network diagrams to make its points. People looking for a detailed understanding of how CallManager works will find themselves delighted. While technicians looking for click-this, click-that procedures will be generally disappointed (such didactic techniques are not typical of Cisco Press books), they will find a fair number of sections that explain, in general terms, how to do such administrative work as loading users' names into a CallManager database and routing calls to emergency numbers. --David Wall

Topics covered: All aspects of Cisco CallManager, versions 3.0x and 3.1, of interest to the people who design, implement, and maintain the IP telephony solution. Matters of system architecture (with plenty of information about hardware and network requirements), call routing, media processing, and reporting are all covered. Does not include details of CallManager's integration with the Intelligent Contact Manager (ICM) business-rules engine, or much information on external Computer Telephony Integration (CTI) applications. ...

5-0 out of 5 stars Better than any other CIPT book in the market...
I studied this book for my CIPT exam. Even though this book itself does not suffice to pass the exam, I could not have done without it either. It provides a clear understanding of CallManager and other CIPT components. All the pictures and graphics are well designed. If I have to criticise a couple points, I would say there are a few organization flaws. Titles could have been organized more effectively. Another improvement could be deviding Route Plan chapter. This chapter is very long compare to others.
Overall, I strongly recommend this book for those who want to understand "Fundamentals of CallManager." Also, if you are studying for CIPT, you should consider "Cisco IP Telephony" book along with this.
As far as practice tests concerns, neither books have enough questions for practice. I had to find a third party question bank to study and it helped a lot. "Cisco IP Telephony" book has some practice questions at the end of each chapter, but I can almost gurantee you that they don't help on the actual test.
Good luck to everyone...

5-0 out of 5 stars A Very Well Docemented Book That Is Clear And Easy To Unders
I did the CIPT training course hoping that it would be enough to pass the exam. Although the instructor was excellent, the documentation was not. It did not couther certain topics in detail, and was hard to follow. As I had to pass the exam for myself and so that the company kept its Cisco Partner Status I had to get some good documentation.

Although I am only half was through this book I am finding it excellent. It goes into good detail on the information, which you have to know, whilst not sending you to sleep on information, which is not relevant to call manager, networking, or telephony. I am confident that once I have read the book a few times I should be able to pass the exam without too much trouble. Cannot say this about the Cisco training documentation.

5-0 out of 5 stars Excellent Book!
There is no more authoritative book on the market on Cisco CallManager. This book answered questions for me that I couldn't find anywhere else. In particular, the dial plan chapters unravel the difficulty of complex route plans and helped me to understand each component of the dial plan process. I reach for this book frequently as I administer my CallManager systems!

5-0 out of 5 stars Excellent In-depth Information about Cisco CallManager
This book includes signific in-depth information that I have not been able to find in any Cisco documentation. After reading this book I have gained a much stronger understanding of the inner-workings of the software. Understanding the architecture of the software will help anyone who is installing, designing, administering, or troubleshooting a Cisco IP Telephony network. I highly recommend this book.

5-0 out of 5 stars THE Book for CallManager Administrators
If you're a CallManager administrator or if your're just interested in learning more about Cisco's IP telephony server, this book is a must have.

The user's guide is fine for setting up the system, but this book does a great job of filling in most of the blanks that couldn't be covered in the manual. For example, the chapter on dial plans (apparently written by the developer himself) is very comprehensive.

I liked the numerous illustrations, but especially liked the illuminating background information that explains not just how, but why the system works.

Highly recommended. ... Read more

3-0 out of 5 stars Convoluted Convolution
I remember reading this book for one of my courses back in college. It's pretty decent but, the section explaining convolution is atrocious. It's only 3-4 pages long and there are only two-in the entire book- examples given. The first, which is trivial, is worked out in detail. The second more realistic example is not. The reverse would have been more a more illuminating situation. This text does a very good job on the other topics covered. Be warned however that the constant shifting between discrete and continuous signals in the book probably will not be how those subjects are taught in a course. Consider using "Circuits, Signals, and Systems" as a supplement.

4-0 out of 5 stars The right book
This book give you much than you need to understand the concepts as well as objective problems and advanced problems in the end of every chapter.
My advise: if you do care about your GPA more than you to understand concepts you may see other texts more helpful in this area and you can even get just the sheets of this book,otherwise this book will make you (as an undergraduate student) understand all the concept to start in DSP and comm.theories.

4-0 out of 5 stars Excellent introduction to the topic
Having had this book for 2 semesters in a Signals and Systems course, I can say that it has done its job in presenting an in-depth and clear introduction to the topic. It is well-written, structured, comprehensive and has lots of challenging (and not so) exercises and examples.

A few comments on the latter: it seemed to me that the first 20 basic exercises at the end of each chapter were very basic, of the type "plug-in the formula from the table on the previous page", while the subsequent problems, especially the advanced ones, are way above the level of the former. Working out through those was meticulous, hard and very lengthy as compared to the basic stuff (the solutions provided by our instructor were of the order 1-2 typed pages per problem). Providing answers or at least general strategies would have been tremendously helpful. I am aware that there is a solutions manual, however the textbook itself is expensive enough.

The information was presented clearly, but I liked our professor's introduction to convolution more that the book's coverage. The sampling chapter was, at least to me and some of my fellows, a bit confusing and we had to, again, rely more on class notes.

Overall this is a good book, albeit very-very expensive (I was lucky enough to get a cheap Indian reprint).

5-0 out of 5 stars Simply the best
This is the definitive text on this topic. Right from the basics of signals to the presentation of complex topics like communication systems, this book beats every other book. The one drawback is that examples are few and far apart. So eventhough those few examples are representative of entire sections, students may find it tough to solve the hundreds of exercise problems.

However I have used many other texts for this course, and only Simon Haykin's text came close.

5-0 out of 5 stars Excellent Intro to Signals
The book was used as the text for a class in Intro to Signals and Systems. I don't think the material could be explained better the first time around. I'll admit the text is quite long winded, and how it seperates continous and discrete/sampled signals into seperate chapters makes each topic even longer. I'll also say, it doesn't do the best job at explaining how to compute convolutions, but was the best I'd seen to date. On the other hand, the book does an excellent job explaining Fourier coefficients and transforms, Laplace and Z transforms, and Nyquist sampling. ... Read more

5-0 out of 5 stars An excellent book about DSP theory!
I've read many books about discrete time signal processing, but none like this! This is the best one so far. Everytime a theory had been explained, an example followed. You know what... I didn't understand DFT until I read this book! Other books explained theories like they were teaching professors, but this book is very excellent for undergraduate students.

5-0 out of 5 stars A very good introduction to DSP
This book covers all the fundamental aspects of the digital signal processing and, like the other works of Prof. J. Proakis, is written in a rigorous but at the same time clear mathematical language; furthermore the author gives practical examples of the applications of the theories exposed. In my opinion a very good introduction and a complete reference text for people who work in the DSP field.

4-0 out of 5 stars Solid Book
I am a graduate student at USC and this book I actually used in lieu of the assigned book Digital Signal Processing (by Mitra). I referred to this book mainly because the assigned book hardly had any intuitive explanations and was quite convoluted. Proakis did a much better job in terms of the relationships between the various Fourier Transforms without comprising mathematical rigor. I also have Lyons Understanding Digital Signal Processing which is great for people new to DSP but I felt it lacked some depth in certain areas and did not have sample problems. Overall Proakis does a solid job with this book. I'd recommend it after knowing the material in Lyon's book.

5-0 out of 5 stars A very well written book
I am currently taking an undergraduate intro to DSP class at Cal Poly Pomona. I have to say that I cannot put this book down!!. Mr Proakis does an excellent job presenting the material in a very readable format. I think this is a very good intro to Digital Signal Processing. The book has a nice flow and does a very good job in introducing the concepts. Another plus for the book are the examples provided. There are some very good problems at the end of each chapter. If you are getting this book I recommend the companion book "Digital Signal Processing with MATLAB" by Vinay K. Ingle and John G. Proakis. I highly recommend this book.

2-0 out of 5 stars Inaccuracies and poor explanations reduce usefullness
I have 6 years experience with digital signal processing, however, it has been so many years since i worked in this field that i purchased this book to update my skills. I found significant errors and very poor explanations in the section on sample rate conversion, the main section of interest to me. For example the sample input to the remez program will not work because you must specify the LGRID parameter even if only to set it to 0 - the example fails to set it. The 5 times interpolation example says that you should set the transition frequency to PI/5 and shows results based on that choice. This is in error, the choice should be Fs/5 (Fs=Sample freq) which produces a very different filter. And all of the Interpolating examples are incorrectly based on this model. In addition i can verify the filter result because it should approximate 0 at every 5th point and the center point of the filter should be 1/5. The book's interpolating filter does not show these properties. And lastly, but perhaps more importantly, the explanations are very ad-hoc providing very little insight into the underlying processes. For example the section on "polyphase" filters is nonsense with regard to signal processing, it is actually a simple programming performance enhancement based on recognizing the attributes of the data. The authors fail to make that clear and in fact obscures everything by describing it in signal processing terms. There are other examples i could provide but i'm only allowed 1,000 words. Sadly, I felt i had to give the book 2 stars because it appears to be the most up-to-date volume available. ... Read more

Book Description

JPEG2000: Image Compression Fundamentals, Standards and Practice is an essential reference for professional engineers and academic researchers in the fields of communication, image processing, signal processing, information theory, and multimedia. It has specific applications for those involved in the development of software and hardware solutions for multimedia, internet, and medical imaging applications, and for those pursuing research in image and video compression.The book is suitable as a primary text for a course in image compression; it would also be helpful in the context of a more general class covering multimedia compression at an in-depth level. Final year engineering undergraduate students pursuing projects in multimedia compression and/or communication would also find the book a useful tool.JPEG2000: Image Compression Fundamentals, Standards and Practice is written in four parts, to serve the interests of a wide readership.

Representing about half the total text, Part I of the book provides a thorough and up-to-date background in the fundamentals of image compression, including topics not previously brought together in a single volume.Part 2 contains a complete description of the JPEG2000 standard. This description is written in such a way as to be completely self-contained from an implementation perspective, while it contains numerous references to the fundamental developments in Part 1. Together, Parts 1 and 2 serve the complementary roles of explanation and exposition in relation to both the JPEG2000 standard and modern image compression techniques.Part 3 of the book is devoted to the implementation and exploitation of the JPEG2000 standard, containing guidelines, suggestions, and analyses for both software and hardware oriented applications.Part 4 describes other key image compression standards, namely JPEG and JPEG-LS. The purpose of this material is to allow the reader to compare the capabilities and complexity associated with these standards with those of JPEG2000. This final part of the book also serves to provide a practical demonstration of some of the fundamental techniques introduced in Part 1 which are not demonstrated by the JPEG2000 standard.About the CD-ROM: Included with the book is a compact disc containing documentation, binaries, and all source code to the Kakadu software tools. This software provides a complete C++ implementation of JPEG2000 Part 1, demonstrating many of the principles described in the text itself. The software is frequently referenced from the text as an additional resource for understanding complex or subtle aspects of the standard. Conversely, the software makes frequent reference to the text and has been written to mesh with the terminology and notation employed therein. ... Read more

1-0 out of 5 stars The book is one of the worst of books I have read
If one wants to learn jpeg2000, he can look for some papers and source codes which are better than this book.
If one wants to learn theory of image coding, he can read some other books much better than this book.

This book is only for fools.

5-0 out of 5 stars Great Work
The author of this book is a genius. His work should be required reading for all. Definatly one of the great minds in our time.

3-0 out of 5 stars Know why you're buying this book
This book is quite good but any potential buyer should know exactly why he would buy it and if it really matches his expectations. Indeed, this book is hardly a helper in implementing jpeg2000, but more a reference book for highly skilled image processing professionals/researchers. It is divided in two parts: the first part is about general image processing topics and provide some explanation about the choices made for jpeg2000. It is the "theorical" part. The second part is about jpeg2000 itself. The latter could have been much more practical and better directed to implementors. In fact, I was thinking of this book being able to clarify some aspects of the norm that are quite blur, but I find the way it is written, even for the second part, overly complicated and scientifically oriented, not "engineering" oriented. Most of the topics are better explained in the norm itself than in this book, even if the latter is much more detailed. Clearly there is room for another book on the topic but this time directed to implementors, with less theory, less scientific notations, are more, much more, real world examples working on real bit-streams. ...

5-0 out of 5 stars The best book (as others reviewed) on UMTS RN planning.
This is the best book on UMTS radio network planning. In fact it is a masterpiece. Well detailed contents, good diagrams and easy to understand plain English. Covers some theory on air interface techniques as well. Warmly recommended especially for RN planning tool designers.

5-0 out of 5 stars This is the Best book for 3G(UMTS) radio network interface
I've read more than 5 books about UMTS air-interface. However,most of books concern only about the physical structure. They didn't tell you WHY the structure is made for. In this book, the explanation is clear and the summary table is really useful. Most of all,it tell you WHY they are made for. Only you know the SPIRIT of physical structure,you will realize the BEAUTY of 3G. I recommand this book for someone with beginning knowledge about UMTS.

4-0 out of 5 stars Very informative , Well-presented but ....
This is one of the best books I've seen and read on 3G matters. Not recommended for those people who are not technical enough (or who hates) to go into the details of mathematical formulas. This book starts with presenting the architecture of UMTS networks and goes on to describe each of the components of a UMTS network (from user equipment up to the core network). Written by people who actually work with Nokia (one of the companies in the world who are at the forefront of UMTS development).

This book can be very helpful to UMTS network planners but it's VERY LIMITED on the subject of optimisation. If you're looking for a book on UMTS (WCDMA) optimisation, this book will not suffice but the subjects of network planning (with and without GSM) are very well covered. Nonetheless, this book is highly recommended !!! 4 stars! ... Read more

An accessible and practical tool for effective antenna design
Due to the rapid development of wireless communications, the modeling of radiation and scattering is becoming more important in the design of antennas. Consequently, it is increasingly important for antenna designers and students of antenna design to have a comprehensive simulation tool.
Sergey Makarov's text utilizes the widely used Matlab(r) software, which offers a more flexible and affordable alternative to other antenna and electromagnetic modeling tools currently available. After providing the basic background in electromagnetic theory necessary to utilize the software, the author describes the benefits and many practical uses of the Matlab package. The text demonstrates how Matlab solves basic radiation/scattering antenna problems in structures that range from simple dipoles to patch antennas and patch antenna arrays. Specialized antenna types like fractal antennas and frequency selective surfaces are considered as well. Finally, the text introduces Matlab applications to more advanced problems such as broadband and loaded antennas, UWB pulse antennas, and microstrip antenna arrays.
For students and professionals in the field of antenna design, Antenna and EM Modeling with Matlab:
* Strikes an important balance between text and programming manual
* Provides numerous examples on how to calculate important antenna/target parameters
* Provides means for modifying existing codes for various individual projects
* Includes a CD-ROM with Matlab codes and antenna geometry files

5-0 out of 5 stars Excellent Introduction, in the opinion of a Telecom newcomer
This is a fantastic book if you want an overview that focuses on technical and some business aspects of telecommunications, and are someone that enjoys reading more techie-oriented material. (For the record, I am an MechE by training who is now working for one of the companies mentioned in the book, so this really was my entire Intro course to Telecom, and I plan to continue my learning. This book was an excellent guide for future, more in-depth subjects to pursue.)

The book does an excellent job of being ubiquitous and covering all the aspects of the telecom field that you've ever heard about. At the same, I found it easy to skip around in reading chapters, based on my own priorities in buying the book. The chapters are divided very logically into sections on the Telephone network, Access technologies, Transport options, Protocols, etc. (if you have no idea what I'm talking about, you will after reading this book :).
One of my favorite aspects of the books is that the author is very good at using diagrams to supplement his text, which can be rare in more engineering/technical books. The whole picture-worth-a-thousand-words idea, especially if you take the time to go through the diagrams.
Yes, the text can require a few read-throughs - but telecommunications itself is a dense field that really requires one to be patience in reading and gain understanding of the technology. There *is* a lot of detail stuffed through out the chapters, and perhaps not everyone will care to know everything -- but that is alright, there is no harm in skipping the nitty-gritty of sections that do not interest you.

Please, please, please do not let the bad reviews of this book discourage you from checking it out. I just finished reading the entire book, and wanted to log on to share my high opinion of it.

2-0 out of 5 stars a scatterbrained mess...
First off, a word of warning: Pay heed to the reader's words from Woburn Mass, all of the 5 star reviews of this book actually are from people who are mentioned in the book's acknowledgements.

I purchased this book mostly to learn about telephony. I already know a lot about data networking, and I wanted to expand my knowledge of other aspects of telecom and optical WAN technologies like SONET and SDH. I knew I was in for trouble after reading about 50 pages. Have you ever read a technical book where you had a really hard time absorbing the info, even when you re-read the same paragraphs over and over again? Well, chances are it's not your fault, it's the author's! I can say this for sure about this book, b/c it described stuff that I already know about, and after reading it, I was more confused than before!

Part of the problem is the author's complete lack of organizational logic. On page 2, he describes all of the "techno-jargon" that permeates the telecom industry, and "often gets in the way of the relatively straightforward task of learning how all this stuff actually works". I totally agree, jargon should not obfuscate. BUT, if you're going to point out this common pitfall, you best avoid it yourself, and Shepard does not! He's all over the board, dropping terms and concepts with little or no explanation. About 10 pages in, it's already a muddled mess.

The mess gets worse. He discusses all of these different approaches to multiplexing, but doesn't take the time to explain what the basic process of multiplexing is all about until page 200! Throughout the entire book, he constantly refers to switching versus routing, but he doesn't explain the basic processes until the final 2 pages! These are just a couple examples that stuck out in my mind.

To be sure, there is some useful information to be gleaned here, but it's hard to sort out from all the "noise". Shepard gets into way too much detail on certain subjects and not enough on others, without any discernable logic. For example, he spends several pages discussing how fiber cables are manufactured, but spends less than one page discussing the basic processes of routing and switching. However, given the topic of the book, isn't the latter subject a lot more applicable? As far as I know, telecom professionals don't need to make the actual fiber cables.

This book is too technical for someone who doesn't know anything about telecom, and it's not practical enough for someone who knows a lot. If you're in between like me, you stand to gain a decent high-level overview of the industry, but the details are murky at best.

4-0 out of 5 stars Excellent Telecom Overview
As an industry outsider with limited technical experience, I found this book informative, easy-to-follow, and entertaining. My compliments to the author for a job well done.

2-0 out of 5 stars entertaining but lightweight
The author has a knack for seeing the big picture and coming up with funny metaphors to describe it (see Austrailian rules football in the other review). Also, he has a lot of friends in the business - four of the 5 star reviews below are from people listed in the acknowledgements. There is technical material here but the selection is sort of random, so you may or may not find a detailed explanation of a subject you're looking for. But his brief discussion of JPEG compression was so absurdly wrong it made me less enthusiastic about reading through the rest of his technical presentations.

I won't say this book is worthless, because he does have a marketer's flair for making business sense of technology and predicting trends, and there is probably enough material here to fill a few good magazine articles. One of them, on the psychology of computer hacking (inserted in the middle of a discussion of the OSI protocol stack), unfortunately has nothing to do with telecom. Also, the mini-Esperanto/English dictionary is entertaining but probably should have been left for the author's web site. I mean, I agree that's funny, but there are those of us who paid for a book on telecom.

5-0 out of 5 stars The complete telecom overview
If I were starting out in the telecommuncations field, this would be the first book that I'd recommend that anyone read. It gives you a high level look at: what protocols do and are used for; what the primary access technologies are; a great description of the telephony system that provides the main infrastructure of the Internet; and, the primary transport technologies that are being used today.
Because this is a "crash course" book don't look for great detail in every topic, however, if you are looking for a compendium that covers the telecomm field all in one book then this is the book you need. My networking background has been mostly in the copper and fiber optic technologies, so I found the sections about the new 802.11 wireless technologies the most interesting. But some of things that I found unique for a book like this and most fascinating are the pictures of scenes and equipment taken inside of actual telephone central offices and the anecdotes about real life happenings in the telecommuncations world. For those of you interested in the state of the telecommuncations industry, you may want to go straight to the last chapter entitled "Final Thoughts" where the author gives some very interesting comments about the industry on a global view.
So if you have anything to do with telecommunications, be it as a user, CTO, IT manager, technology student, technology teacher, marketing or sales person of telecom or buyer of telecom, then this book should have a place on your desk. ... Read more

4-0 out of 5 stars One-stop gateway to the telecom world, but don't stop here.
I am the officer technical lead for a 50-person military intrusion detection operation. I read Mr Green's book to get a broader understanding of the telecom world, of which network intrusion detection occupies a small but highly visible part. This immense book (774 pages of text, plus URLs, acronyms, and a glossary) addressed nearly every topic I had encountered reading communications magazines, speaking with the telecom industry, and researching the Web. While no single book can provide the depth needed for truly understand a specific technology, Mr Green's work provided the foundation for future research. For example, after getting the context for SS7, I may now buy "Signalling System #7, 3rd Edition" by Travis Russell. I didn't give the book five stars, as I was not completely comfortable absorbing the material. This is the sort of book that requires you to read the whole book twice in order to appreciate the early chapters. References to technologies like ATM or frame relay in the first half of the book make much more sense after reading chapters dedicated to those issues. If Mr Green had given me slightly more to grasp while reading the early material, or had perhaps organized the book with the telecom novice in mind, I may have given five stars. Nevertheless, if you're looking for one-stop shopping for telecommunications, I highly recommend this book. Don't be fooled by the "business" classification on the dust jacket -- this book is a technical volume, with protocol headers and other details included. Great work Mr Green!

5-0 out of 5 stars Technical and Readable
The Irwin Handbook of telecommunications is both technical and readable. It is an excellent text for telecommunication students,managers, and vendors. The field of telecommunications is rapidly evolving.In the future ,jobs and fortunes will be won and lost by those who apply winning technologies. Consider this book a score card. You cannt tell the players without a scorecard.

5-0 out of 5 stars The best book on telecommunications I have ever read.
I read this book about a year or so ago, and I have been looking for it since then. It is the best book on telecommunications I have ever read. It goes into great depth of Switching, SS7, VMBs, PBXs, Centrex, ISDN, etc. Definitely a good buy.

Book Description

This reader collects the texts, videos, and computer programs--many of them now almost impossible to find--that chronicle the history and form the foundation of the still-emerging field of new media. General introductions by Janet Murray and Lev Manovich, along with short introductions to each of the texts, place the works in their historical context and explain their significance. The texts were originally published between World War II--when digital computing, cybernetic feedback, and early notions of hypertext and the Internet first appeared--and the emergence of the World Wide Web--when they entered the mainstream of public life.

The texts are by computer scientists, artists, architects, literary writers, interface designers, cultural critics, and individuals working across disciplines. The contributors include (chronologically) Jorge Luis Borges, Vannevar Bush, Alan Turing, Ivan Sutherland, William S. Burroughs, Ted Nelson, Italo Calvino, Marshall McLuhan, Billy Kl?Jean Baudrillard, Nicholas Negroponte, Alan Kay, Bill Viola, Sherry Turkle, Richard Stallman, Brenda Laurel, Langdon Winner, Robert Coover, and Tim Berners-Lee. The CD accompanying the book contains examples of early games, digital art, independent literary efforts, software created at universities, and home-computer commercial software. Also on the CD is digitized video, documenting new media programs and artwork for which no operational version exists. One example is a video record of Douglas Engelbart's first presentation of the mouse, word processor, hyperlink, computer-supported cooperative work, video conferencing, and the dividing up of the screen we now call non-overlapping windows; another is documentation of Lynn Hershman's Lorna, the first interactive video art installation.

5-0 out of 5 stars Rosetta Stone of Hypertext
This huge tome is a must have for anyone who wants to deeply understand hypertext and its precursors. From William Burroughs to Doug Englebart and Augosto Boal to Ted Nelson this book presents a huge range of articles (and discursive commentary) of interest to computer scientists, writers, new media workers, artists and everyone in between. This is one stop shopping for new media literacy with over 800 pages of good stuff, much of it very hard to find outside of this volume.

4-0 out of 5 stars Dated but still good....
Even though this book was first published in 1995, it still serves as a useful research and reference guide to those involved in changing the TCP/IP protocol or the mathematical and simulation modeling of it. Most of the source code is included for the protocol and UDP is treated also, with Berkeley TCP/IP used as the protocol implementation. A brief introduction to descriptors and memory buffers is given in Chapter 1, along with a discussion of input processing. The authors treat memory buffers (Mbufs) in detail in Chapter 2. Four different types of Mbufs are used in the protocol, depending on the flag setting in the m_flags member of the header. The source code clearly illustrates the data structures used for the Mbufs. This is followed by a detailed discussion of the Mbuf macros and functions. This is followed in the next chapter with a discussion of the interface layer and the all-important sockaddr data structure. In addition, the system initialization procedures are treated very nicely. This is followed by a very informative overview of the Ethernet interface, with most of the source code omitted since it is hardware specific. The LANCE driver is discussed thoroughly in this chapter. Then, in the next chapter, the SLIP and loopback interfaces are discussed with a very effective diagram used to illustrate the device drivers. The authors do manage to spend a few helpful paragraphs on SLIP performance considerations.

Chapter 6 is a very detailed treatment of IP addressing, the most useful discussion being the one on the in_ifinit function. This is followed by a discussion of the data structures used in domains and group protocols, with the IP initialization and transport multiplexing discussion being of particular interest to me.

The next 3 chapters give an overview of the IP layer, with IP packet structures and processing, option processing, and fragmentation and assembly all given detailed treatments. The performance issues involved in computing checksums and data copying are discussed also. The treatment of timeout processing by the function ip_slowtimo, which is very important from a modeling perspective, was given a thorough treatment.

ICMP is discussed in Chapter 11, with an extensive table included of the ICMP message types and codes. The discussion on error processing was particularly useful. This is followed in Chapter 12 by a survey on how IP multicasting is implemented along with Ethernet multicast addresses. A brief discussion of performance issues involved with Ethernet cards not supporting perfect filtering is given.

IGMP is then taken up in the next chapter, with a good discussion given of the virtual interface table in IP multicasting given in the next chapter. The authors carefully discuss the difference between physical interfaces and tunnels.

The most useful discussion in the book for me was the one on sockets in chapters 15, 16, and 17. The code for the socket data structure is given and a very detailed overview of socket system calls is given. The discussion of the listen and accept system calls is very helpful in understanding the process by which TCP sets up a connection. A full description is given of each macro and function involved in socket buffer allocation and manipulation.

Tree routing tables are discussed in chapters 18, 19, and 20, with emphasis on the structure of the radix tree routing tables used by packets, the interface functions between the kernel and the radix tree functions, and the routing sockets used to exchange routing messages. The discussion is extremely detailed, and the authors take great care in explaining the relevant data structures and function calls used.

ARP is discussed in Chapter 21, with a useful diagram given illustrating the relationship between ARP and routing tables and interface data structures. The structure of the ARP packet when transmitted on an Ethernet channel is shown in detail. Most interesting was the discussion on the algorithm used to avoid ARP flooding.

Protocol control blocks are discussed in the next chapter, with detailed treatments of binding, connecting, and demultiplexing. The handling of ICMP errors with the in_pcbnotify function is surveyed, with a detailed diagram summarizing how ICMP errors are processed.

The actual UDP implementation is discussed in Chapter 23, and the authors show how checksumming is done in this protocol. This is followed naturally by a discussion of the TCP implementation in the next 6 chapters. The reader can clearly see the difference in complexity between UDP and TCP in terms of the number of function calls and lines of code. A complete listing of the statistics used in the tcpstat data structure is given along with a listing of the SNMP variables used in tcp group. The TCP state transition diagram, familiar from Volume 1 by Stevens is given here also. The discussion of the seven TCP timers is very detailed and very helpful to those involved in the modeling of TCP performance. In particular the discussion of the tcp_xmit_timer function, which updates the smoothed RTT estimator and the smoothed mean deviation estimator, is very well written. Retransmission timeouts, the occurrence of which is so important in performance analysis and network troubleshooting, is given ample treatment also. Most interesting was the discussion on determining when a segment should be sent, via the tcp_output function. Also, the reassembly mechanism with the tcp_reass function is discussed in great detail. The reader who needs to be a TCP expert should take away a thorough understanding of it when completing these chapters.

The book ends with a fairly detailed treatment of the BSD Packet Filter and raw IP.

Noticeably missing of course, because of its age, is a discussion of the different versions of TCP/IP currently implemented in Windows 2000, Sun Solaris etc, which are slightly different. The reader will have to consult the Web or modern books to get an understanding of these implementations.

5-0 out of 5 stars A difficult read but well worth it
I bought this book shortly after finishing Volume 1. With volume 1, I found myself staying up late to read more, but volume 2 gets tiring after a while... it's literally a detailed analysis of every single line of networking code in the BSD 4.3 kernel. Although it's well worth the effort, I found myself reading no more than about 10 pages at a time (constantly flipping back, sometimes almost all the way to the beginning, to re-read something I hadn't quite absorbed the first time).

Difficulty aside, this book alone will honestly make you a TCP/IP guru - now that I've read volumes 1 and 2, the networking administrators where I work come to me with questions about issues they can't resolve. I'm literally comfortable saying that there's nothing I don't know about TCP/IP, and that's not a statement I'd make lightly (feel free to test me). But more than that, I learned a *lot* about writing good, solid code... in learning the networking stack as a whole, I was able to understand some higher-level software engineering concepts that had previously eluded me.

All in all, volume 1 is The Hobbit, and volume 2 is the Lord of the Rings - an oddysey not to be undertaken lightly, but from which you will emerge stronger and more powerful than ever before.

5-0 out of 5 stars Impressive
If you want to know the internal mechanisms used to build an IP stack, and how the mechanisms are implemented, this is the book to refer to. The level of detail is very impressive. Although Vol.1 can be read as a text book, Vol.2 is really a reference book with a large quantity of code. It is very easy to read and well indexed (very important for a book of this nature). Simply put, it's one of the best TCP/IP implementation books I've encountered yet.

5-0 out of 5 stars Overview
An elaborate description of network implementation and working of transport layer protocols. Like all of Richard Steven's books, this one too has a large number of code examples to explain the usage of
the data structures and the API used for writing networking applications. The book offers a great index for backreferencing.
Covers all important layer 3 and 4 protocols and the various services offered by them. The code examples provide an excellent first step for starting network programmers and a useful reference for the experienced.

5-0 out of 5 stars stupid windows whore [WAS: Useless for Windows...]

2-0 out of 5 stars OK but could be much better written
The information contains in the book makes it a pretty good primer on SIP. The organization of the book and its content is very good. The language and ways in which the author explains certain things are confusing. I think the author should be able to do a much better job in explaining things. I often find myself having to re-read certain explainations twice and much carefully when I feel I shouldn't have to -- the topics are not complicated but not well explained. Someone like Doug Comer or Richard Stevens would probably be able to make it a much easier read.

4-0 out of 5 stars Costly, but a great introduction to SIP
Really enjoyed this book - easy to read, and the examples emphasized the points he was trying to make. The only negative is the cost of the book ... I got mine from the library, and was shocked to see how much this was selling for. After you understand SIP, this would be a decent reference book, but not the best.

3-0 out of 5 stars Just an introduction to the SIP RFC
This book simply summarizes some of the SIP RFC into more user-friendly english. It consists mostly of lists of SIP headers and error codes, lifted from the RFC. There is no sample code or discussion of SIP applications or architecture. Of course, the RFC is pretty hefty, so this book has been a useful introduction. I still use the RFC as my real reference, though, because there are some minor discrepancies between the book and the RFC, such as some error code names.

5-0 out of 5 stars An Excellent Primer
I've read and reviewed a great deal of technical literature, and found Dr. Johnston's book to be a detailed and well-written introduction to an extremely complex protocol. Without over-simplifying, Dr. Johnston, manages to convey a great deal of information in a style of writing that is lively and engaging (and that's a real breath of fresh air, compared to similar books on the topic). I plan to put this on the required reading list for my next class on the subject.

2-0 out of 5 stars Not bad, but not the best
I found the book useful as a backup reference to the spec, but not the best explanation I have seen. It was at times slightly confusing, and found that I was constantly referring back to the SIP overview in D. Collins "Carrier Grade Voice over IP" (which is very well written). From an education perspective, it was a little like a dictionary for SIP that explained concepts such as what a given header was for, but gave little info on how it is used, or what the industry is doing.

There were some call flows, but they were sparse with a few mistakes. Further, they were either very base, or very comprehensive, and did not cover many of the questions I had.

In summary, if you are looking for a readable reference to help with the not so reader friendly RFC, this is pretty good. For learning how SIP is being imlemented beyond basic call handling, keep looking.

As an option, also look at the book by Collins noted above. It is a good overview reference, and tries to address where the industry is moving from an implementation perspective ... Read more

Book Description

Telecommunications policy profoundly affects the economy and our everyday lives. Yet accounts of important telecommunications issues tend to be either superficial (and inaccurate) or mired in jargon and technical esoterica. In Digital Crossroads, Jonathan Nuechterlein and Philip Weiser offer a clear, balanced, and accessible analysis of competition policy issues in the telecommunications industry. After giving a big picture overview of the field, they present sharply reasoned analyses of the major technological, economic, and legal developments confronting communications policymakers in the twenty-first century.

Since the passage of the Telecommunications Act of 1996, when Congress fundamentally reoriented the existing regulatory scheme, no book has cogently explained the intricacies of telecommunications competition policy in the Internet age for general readers, students, and practitioners alike. Digital Crossroads meets this need, focusing on the regulatory dimensions of competition in wireline and wireless telephone service; competition among rival platforms for broadband Internet service and video distribution; and the Internet's transformation of every aspect of the telecommunications industry, particularly through the emergence of "voice over Internet protocol" (VoIP). The authors explain not just the complicated legal issues governing the industry, but also the rapidly changing technological and economic context in which these issues arise. The book includes extensive endnotes and tables that cover relevant court decisions, FCC orders, and academic commentaries; a glossary of acronyms; a statutory addendum containing the most important provisions of federal telecommunications law; and two appendixes with information on more specialized topics. Supplementary materials for students are available at

5-0 out of 5 stars That rare combination: comprehensive and accessible
Digital Crossroads is that rare combination, a comprehensive and accurate -- but well-written and accessible -- presentation of the state of the technology, economics, and law driving today's complex telecommunications industry.I used it in my Albany Law School seminar on Telecommunications Law for the 21st Century, and students found it highly accessible--especially the technology chapters.The book is a real accomplishment: comprehensive, thoughtful, and forward-looking, without being swept away by the latest gimmick off the shelf.It is also an extremely well written and organized book, clear and authoritative.In addition, for either the practitioner or academic, the inclusion of relevant sections of the 1996 Telecommunications Act adds value and convenience. Making coherent sense of this industry, its history and trajectory, is a daunting challenge and one the authors met, apparently without flinching.

5-0 out of 5 stars Telecom Law for the Layman, Clearly Explained
If you need a current understanding of the law and politics around telecommunications today, this is THE book you need.While long, it is clearly written, concise, lucid, and technically excellent.Even with extensive experience in this domain, I found this book to be the most cogent and readable summary of the issues today, and I learned a lot in the process.

Jonathan Nuechterlein and Philip Weiser are practicing lawyers that have taken the time to learn enough of the engineering and technology of the telecommunications world to be able to explain the intersection of law, politics, and technology to anyone with an interest in the topic.Their goal with this book is to lay a foundation for revisions to US (and global) laws as they apply to voice, data, and video communications distribution networks.While they do not have the answers yet (no one does), they lucidly and often humorously explain why today's laws and regulations are increasingly obsolete.In the process, the authors describe how technology and software are interacting to force the government to abolish the regulatory divisions between the voice and video worlds.

Nuechterlein and Weiser outline a four layer model for communications policies of the future, dividing the domain into 1) the physical infrastructure layer, 2) a logical connectivity layer, 3) an applications layer delivering voice, video, and data services to end users, and 4) a content layer that addresses publicly visible content in any format.They illustrate how this model can be used to devise laws that can effectively achieve the goals of government, and, more importantly, how the model can demonstrate the weaknesses of existing and proposed laws and rules.As they do this, they outline the thinking from the best minds in this domain as to the direction that Congress and the FCC should take in the process of revising our laws on the Internet, traditional voice telephony, VoIP, satellite communications systems, cable TV and the broadcast TV industry.

For this reason and others, I highly recommend this to anyone needing to understand the current regulatory environment surrounding the Internet and telecommunications generally.You will not go wrong with this volume. ... Read more

Book Description

This book offers guided access to a collection of algorithms for the digital manipulation and analysis of images. Written in classic "cookbook" style, it reflects the authors' long experience as users and developers of image analysis algorithms and software.For each task, they present a description and implementation of the most suitable procedure in easy-to-use form.The algorithms range from the simplest steps to advanced functions not commonly available for Windows users. Each self-contained section treats a single operation (histogram evaluation, low-pass filtering, and edge detection, among others).The coverage includes typical situations requiring that operation and then discusses the algorithm and implementation.Sections start with a header illustrating the nature of the procedure through a "before" and "after" pictorial example and a ready-reference that lists typical applications, keywords, and related procedures.Annotated references can be found at the end of each section. An accompanying CD-ROM contains a collection of C programs for carrying out the book's procedures. ... Read more

The book is just great! I used the source code from the CD-ROM for various image processing projects. The algorithms are also very practical if you have to deal with images. The code is neat and ready to compile and run.

Also this book is good on the description of image process and image analysis algorithms. I read the whole book and use it as a reference during my programming. It sits in my bookshelf and I use it almost everyday.

I recommend anybody who wishes to do serious image programming to have this book. It's just great!

The title says it all. This book was meant to be used. It is organized around a series of transformations that are performed on an image in going from the raw, captured form to usable result. Each step is well identified so you can go directly to the part you need. The methods and routines used are the author's choices, but they give enough information so you can dig deeper if you suspect you may have special needs.

I particularly liked the illustrations. They aren't fancy coffee table illustrations but they are very clear and pointed to what is being discussed. There are many illustrations that show the effect of the procedures on actual images from a variety of fields.

There is a CD-ROM of the executable programs.

5-0 out of 5 stars Knowledge Management (and Sharing) for the Call Center Set
Perhaps it is the human dimension of contact centers that make them so difficult to understand. Contact / Call centers are one of the few corporate functions where technology has been truly and deeply integrated with the workers. This places the proper operation of the environments firmly in two camps - operational managers and technologists. Few of these managers have had the opportunity to spend the time and attention to become expert in both. The specific and granular details of the integration of people and technology in these environments has not been comprehensively recorded until now.

Call Center Technology Demystified captures many of the best practices for technology planning and implementation in call center environments. The discussion is properly deep to allow readers the ability to move beyond buzz words and on to concept understanding. Powerfully illustrated with functional and technical views, this book is a invaluable for visual learners. Comprehensive descriptions of the multiple data reporting sources, detailed CTI call flow, and self service technology interactions are specific examples of work that would take business analysts weeks to create.

Call Center Technology Demystified will prove to be a powerful tool to increase the relavent pool of business professionals who understand the technology and operations of complex contact center environments. I recommend it as one of the fastest ways to attain a grip on the many layers of technology that have developed in contact centers and how to leverage this technology forward.

5-0 out of 5 stars Call Center Technology Demystified is a perfect reference !
This book is the first I know of that matches business strategy to technoloy implementation. It has an amazing amount of nitty gritty detail on each of the diverse call center systems, and then collects the details into a big picture. Managers can use this text to plot a beneficial technology roadmap instead of just buying "stuff". I have already used this book with clients and highly recommend it to anyone who runs a call center or who is responsible for implementing customer contact technology.

4-0 out of 5 stars Technology Demystified and Explained
One of the best call center books on the market, Call Center Technology Demystified gives a practical explanation of call center technologies in language a non-techie person can understand. We have found it valuable in our call center in helping our management team understand what to purchase and how to get the most out of their technology investment. Good work!

5-0 out of 5 stars Essential book for Contact Center leaders!
I have what I feel is a pretty extensive contact center reference library that I have accumulated over the past 15 years, ranging from call center design, CRM, CTI, speech recognition, benchmarking, telecom, etc. By far, the Call Center Technology Demystified book is THE book that I find myself referring to most often. Besides the holistic view of the contact center technologies, I have found the sections on Building a Customer Contact Technology Strategy and Information and Applications Bring CRM Strategies to Life sections to be valuable every day, every project. Great diagrams and charts add tremendous value to the clear and concise writing. This is also a book that will stand the test of time; the principles surrounding business drivers and the realistic expectations regarding CRM will provide value to contact center strategists for many years.

4-0 out of 5 stars Practical guide to call center technology
I have always been impressed with the fact that Lori and Dave view call center technology (and call centers in general) from a strategic viewpoint. Everything they do starts with asking overall business strategy questions. Call Center technology will only really be effective if it supports the overall business objectives. This is how Lori and Dave approach their consulting work, the seminars they conduct and how they approached writing this book. One of the great practical elements to this book, in each chapter there are numerous tables summarizing the strengths/weaknesses, pro/con, advantages/limitations for numerous elements of call center technology. I found these tables to be very useful, not only as a synopsis of what they just got done saying but also as a tool for a quick reference and a framework in formulating your decision making process. They also give examples of what the technology vendors will say about the technology so you as the technology buyer have a much better idea of how the vendors view and approach the technologies they are trying to sell you.

Overall, this book is a great value for your money. You should be able to make better call center technology decisions after reading and using this book. This book is very practical and one you will want to reference over and over again. ... Read more

2-0 out of 5 stars Pretty light
If I had not seen the Gorden Stuber book I would have given this book only 1 star. However in comparison, it does deserve at least 2.

This book has all the stuff you would want in a wireless text book. It covers fading, Rayleigh, Rician, GSM, AMPS etc. My major complaint with the book is THERE ARE NO EXAMPLES. Per chapter there are probably 3 or 4 examples, but none of them are really challenging.

For instance in the fading chapter, the examples are on coherence time only. How about a couple examples that actually use the fading PDF's/CDF's. We spend so much time "discussing" the distributions, maybe it is time we actually use the distributions?

Compared to "Principles of Mobile Communication" the book is marginally better. For one it is not as heavy on the math, and it does a better job explaining pretty well everything.

However.. I feel I learned far more from Shankar's wireless book in undergrad.

5-0 out of 5 stars Good Introduction to Wireless Communications..
A must-have for a beginner in the field of Wireless Communications. The author covers a wide range of topics starting from basic Cellular System engineering to topics like mobile channel characterization, fading and diversity, channel coding, modulation etc.. The book also provides a very good introduction to First and Second generation Mobile communication standards. The authors style is very good and easy to understand. A lot of unnecessary math is avoided and very good overview is presented.

But the thing I liked the most in this book is the exercise problems at the end of each chapter and the references. Working out the problems in the end will help a lot in gaining a deeper insight into the concepts explained in the book.

Overall.. this book certainly deserves 5 *'s !

2-0 out of 5 stars Unorganized textbook
this book is not good for the beginner in wireless communication. I have to use this textbook, because it's the requirement form my instructor.

the author didn't organize this book as well as he should. All equations are not well explained...Sometime the students need to guess where this variable stands for or what parameter's meaning is. He wrote like the literature or space for equation's explanation...all of them are in the same paragrah.

i really don't recommend this textbook and i still don't understand why my instructor uses this text

5-0 out of 5 stars The best text for a new engineer or student to wireless
This text is by far the most comprehensive and useful for explaining all facets of wireless communications. I had this text for an entry graduate class, and found the examples, writing style, and organization to be first rate. The description of 3G systems and WLANs in Chapter 2 was very useful and helped when I later had to read the standards for employment. This text will continue to get good use on my bookshelf. It also has a very thorough index and appendices with many tables, formulas, explanations, and useful engineering matter that I seldom have ever found under one cover before.
Great for students and practicing wireless engineers

2-0 out of 5 stars Caveat Emptor
As a lecturer in Mobile Telecommunications I was concerned that this book is light on detail in some places, and authoritatively wrong in others. For example, the author makes basic errors in his description of the GSM logical architecture (particularly with respect to the network databases) and he does not describe the current HR and EFR GSM voice codecs; the section on IS-95 CDMA does not describe soft handoff or cell identification in detail and has not been updated to describe IS-95A. His derivation of Erlang B is also missing a number of key steps. These factors make this textbook unrecommendable for my students. A THOROUGH revision is in order for the next edition. ...

4-0 out of 5 stars A very concise, to-the-point text.....
This is an exhaustive text on practically every known technique used in practical error correction/detection. Every individual technique is outlined in a seperate chapter, with a lot of stress on the practical implementation issues, though it does go heavy on the computational nuances at some places.

This book shall require you to have a very solid background on vector/matrix math, and also Galois field arithmetic. Some basic knowledge of Communication System models is also recommended, though not mandatory.

The down side of the book is that it does not give exhaustive mathematical proofs of the various algorithms (It was not the original intention of the author in the first place, though it's inclusion would have been really helpful), and secondly, there is no comparative analysis of the various algorithms. In this regard, implementing them in C/C++ could be very instructive to the discerning student.

2-0 out of 5 stars Beginners... Don't waste your money
In contradiction to an earlier post which expressed this was a good book for beginners, I would highly recommend beginners and those with desire for practical implementation to buy Lin and Costello's book. This book lacks in the quality and quantity of its examples. It may serve as a good reference for the more theoretically motivated person (e.g., those in the academic publishing community) but if you want to own just one book, don't get this one.

3-0 out of 5 stars Well written by already outdated
The book is very well written specially as an introductory book. However, some important derivations & discussions are missing. Two examples:(1) there is a whole chapter on BCH and Reed Solomon decoding without the derivation of the Berlekamp-Massey decoding algorithm, not even in the appendeix. (2) When discussing different decoding algorithm, no effort is spent in quantifying the complexity of different algorithms. So, the reader has to take the author's word that algorithm X is simpler than algorithm Y. Current hot topics such as Soft decoding of BCH and Reed Solomon codes is not discussed, except for the traditinal erasure decoding algorithm. Similarly, iterative decoding is not discussed; instead we have the outdated Fano and Stack algorithms that are usually covered in older books.

In summary the book is well explained but the subjects are not well chosen.

5-0 out of 5 stars Good Reference Book
I use this book at work and several co-worker have borrowed the book. Evereyone who has used the book has found it very useful. The book has been used as a reference for implementing error-correcting codes on FPGAs. The examples in the book are excellent and the book could be used as a comprehensive text on error correction. The author starts with the basics and goes into great detail on both block and convolutional codes.

4-0 out of 5 stars Delivers the Goods
Once you get past the (very necessary) finite field stuff you're hip deep in everything you ever wanted to know about codes - block codes, convolutional codes, binary, ternary, you name it.

I found the discussion of Reed-Solomon codes particularly good. So *that's* how they work!

Some new stuff missing (Turbo Codes), but that's always going to happen. ... Read more

5-0 out of 5 stars Great Book for Developing GPS Tracking Systems
This is a great book to read if you plan on developing any type of GPS tracking system. While the book covers the the basics, you'll need some further resources on interfacing GPS receivers and such hardware to real-world devices.

An interesting article entitled "Tracking a Vehicle With GPS" can be read at

A lot of mobile solutions are soon to hit the market such as mobile phones using GSM or GPRS to track a person. This book will help to understand how it all fits together. It would have been nice if the book could have touched on how older communication systems like VHF radios can transmit GPS data. For that you'll have to visit or some other website with such resources.

5-0 out of 5 stars Clearly the Best General Reference on GPS
I've been an engineer and PM working with GPS and GPS systems since the inception of GPS in the mid-80s. While employed by a major DOD research lab I was fortunate enough not only to have access to practically every GPS book and article available, but I also had the opportunity to meet many of the key people responsible for the design and development of the system (many of whom contributed to this text). From system design to receiver architecture, this is by far the best general reference I have found on GPS.

5-0 out of 5 stars Excellent to Pratice the GPS Technology
This book has entire body of knowledge concerning GPS concept , control, satellites operation , propagation, receivers, and extra to Explain the Differential GPS Error correction and more. This book is ULTRA suitable for student and engineer, also suitable for the people who want to practice GPS Theory in Detail.

5-0 out of 5 stars Good Book
I have been interesting GPS for 5 years and used GPS for land navigation, for INS aid, for DGPS purposes. I have read about 9-10 books on GPS. This book is the best one. It has a good introductory information, clear theorical chapters. Applications of GPS are also covered very well. I suggest this book both new and advanced GPS related people. ... Read more

2-0 out of 5 stars paper wasted sip book
Author is really good but the way SIP described in the book is a kind of child-story , details on important parts of SIP and on unified services are skipped instead make-up parts are highlighted.

3-0 out of 5 stars Skip the first half
I found this book covered too many points on the spectrum. The first half goes over everything BUT SIP. Most people who want to learn the generic SIP structure already know how a simple telephone and data network operates.

This takes a little too long to get the the "meat" but from there on gives a pretty good detail of the SIP format for anyone looking at understanding the basic SIP code format.

As a fundamentals book for anyone wanting to start learning SIP programming it would be a good reference to have on the shelf. Skip the first half though.

5-0 out of 5 stars The best SIP book for beginners
This is the best book for who wants to know about SIP initially, especially on what SIP can do conceptually. This book is feasible for everyone that includes executives, managers and engineers. This book also provides very good related information in the Internet Forum.

5-0 out of 5 stars My best book to understand SIP
SIP Demystified covers not only SIP protocol itself but also why SIP is so good in Internet world. That would help us to understand SIP so much. Especially, this book is recommended to, like me, those who are moving from switched voice into a data networking environment as editorial reviewer says.
I hope that SIP Demystified will be translated into Japanese soon for my colleagues or friends.

5-0 out of 5 stars the best Cisco IP telephony book resource
I have nothing bad to say about this book. It's an excellent resource for someone who daily works with Cisco IP Telephony.

Edit: I've just finished the book. I'm very impressed. I'm taking CCIE Voice lab in September '03, and hopefully this books turns out to be an invaluable resource for this test.

5-0 out of 5 stars Good overview of the tools available.
I have to admit that this is not a book that I have read cover to cover. I have dipped into it to cover topics listed in the CCIE voice exam. I have found it to be very useful in that respect. For each topic it gives an overview and brief details on configuration before going on to explain how to troubleshoot problems. It will not replace the troubleshooting resources available on CCO, but it will give you a great place to start!

Now that I've read it I can answer the following questions:

Would I buy it to help pass the Troubleshooting Exam? - Yes (but I have not done the exam so difficult to say for certain)

Would I buy it to help pass the CCIE Voice written exam? - Probably, but would need more information from CCO.

Would I buy it for my reference bookshelf? - Definitely. ... Read more
