Rating: Summary: Not worth reading Review: I am not new to VoIP, and I know it fairly well already (attend the standards bodies, etc.), but I needed to find a good book for other employees. This was not it. Uyless left many errors, many open topics, and frankly the book is not really about Voice over IP in detail. There are much better books out there: Olivier Hersent's "IP Telephony" and Duskalis's "IP Telephony" are much more thorough on VoIP (despite their titles), although they are somewhat out of date already. (anything over 6 months old will be)
Rating: Summary: This book is not about voice over IP Review: I am unhappy. Each time I get a book about voice over IP I feel cheated. This book is about all sorts of things but it is not about voice over IP. The author exercises his knowledge on many interesting topics. Some of them are related to voice over IP but most of them are padding. This book fills most of it's chapters with related subjects like SS7, PPP, telephony etc... The author missed the mark with this book. This is the fourth voice over IP book I have read and if you took all four together you may get a half decent. What is covered is H.323 and MGCP both are not badly covered but they zoom down to the bit level far too quickly without really giving the reader a grasp about their real meaning. The book does state that some sections are needed for completeness, but they ramble on without a good general direction. Again I shall continue seeking knowledge, but this whole topic area is quite badly covered. My advice is to read the ITU recommendations for H323, T.120, Q931 etc...
Rating: Summary: Good Service Provider Reference Review: I have implemented several voice over IP systems, and I find Uyless' book to be an excellent technical reference. It covers much of the technical information that vendor documentation leaves out and is more readable than an ITU Spec. The call flow information is useful, and the ASN.1 references are the first that I have seen. This is not for a beginner but provides nice insight.
Rating: Summary: Not worth reading Review: I have mixed feelings about this book. There is a lot of good information, but it is full of typographical errors that left me feeling like I was reading a rough draft. I'm a graduate student and I bought this book looking for a good tutorial on VOIP. After reading the reviews and seeing the table of contents, this looked like the right book for me. I agree with some of the other reviews that certain areas were covered to briefly. However, the author does a good job of trying to bring together all the pieces of VOIP. The meat of the book is in the later chapters on H.323, MGCP and SS7. I would have been satified with this book were it not for the NUMEROUS errors. Examples are "next work" instead of "network," "trucking" instead of "trunking", paragraphs repeated on the same page, references to incorrect figures, incorrectly labeled figures, mis-spelled acronyms etc. I kept trying to overlook these mistakes while reading the book, but there were so many that I coudn't. The book has many good tables and specifications, but the quantity of errors throughout made me question the accuracy of these too. Bottom Line: Wait for the second edition. This book coud be really good, but it wasn't ready to be printed yet.

Rating: Summary: Why Black is the master in Voice Over IP Review: I was truly impressed by this title and frankly can't agree with some of the other critics. In actuality, they helped me buy this book because Voice Over IP by Ulyess Black is exactly what I have been looking for. After all, we are talking about Voice Over IP. While it does touch other areas, I really liked this book because it also covered other key areas of networking... things I must understand or reinforce before I need to learn Voice Over IP. And he does this quite well. Did he teach me something I already knew? Yes, but some of it I had forgotten! Did he teach me something I didn't know? Definitely! And this book allows me to walk away with a better understanding of Voice Over IP. I'd click on the TOC in the left hand column. I think you'll agree. While I don't know Mr. Black, he's sure taught me a lot. And thanks to Prentice Hall for such a great book!
Rating: Summary: Where was the editor? Review: The typographical errors in this book make it useless. I had some knowledge of this subject prior to reading it. The parts I was familiar with were so full of errors, that I could not trust any of the rest of it. Based on the price I paid, I think the publisher should pay me to send back the corrections! I am sure there is some useful stuff in here, but weeding through the junk is not worth it. In the section on MGCP, the acronym "MGCP" is spelled at least 3 different ways. DO NOT WASTE YOUR MONEY ON THIS ONE!
