Not worth reading
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and Duskalis's "IP Telephony" are much more thorough on VoIP (despite their titles), although they are somewhat out of date already.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)

Where was the editor?
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!

A Good Rough Draft - Rushed to Print
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.
