Summary: A lot of very valuable information
Review: The book does a good job of both explaining the topic and providing hands on examples. All of the current generation products are covered (2600, 2600, AS5300) in detail as well as information on the next generation. If you're tired of wading through the Cisco web site to extract all of this info, buy this book.

Summary: Useful Book for those new to packet voice
Review: The first couple of chapters provides a decent background on basic telephony and then moves on to discuss some of the emerging protocols and technologies. I would have liked even more configuration examples but all in all this proved to be useful.

Summary: Strategic, tactical and technical
Review: The revolution of voice over data networking promises to lower costs, increase performance and transform companies' business communications strategies - and we all need to know about it. This book provides an indepth insightful presentation of both the big-picture strategic benefits and the down-dirty plumbing particulars. A truly valuable reference material.

Summary: I've been waiting for this book.
Review: This book does a great job of explaining how to actually plan and configure a voice-ip network. It manages to clearly explain some very complex topics and provides good examples and configuration scenarios.

Summary: Stop! This is the worst tech book I have ever read.
Review: This book is not for tech people at all. If you want to learn Cisco's VoIP configuration, Cisco's web page is the best place to go. With this book, you will never know how to configure Cisco's VoIP. I bought this book and returned it right away after I took a look. Indeed, this is the worst network tech book I have ever read.I also want to remind the authors of this book: don't waste the readers' time!

Summary: Very Bad!
Review: This book is supposed to be about VoIP. Then why is the whole last 1/3rd of the book on IPv6? It is not mentioned in the title or description, yet it is a significant part of the book. I suspect the author didn't know VoIP very well and had to pad. The VoIP parts just introduce concepts and discuss Cisco command line a little bit, but there aren't enough examples or detail to teach you anything about VoIP. It isn't even very good reference material. I wish I hadn't bought this book!

Summary: Absolutely worthless
Review: This book is without a doubt the worst book on Cisco networking that I have ever read. It doesn't cover any of the VOIP protocols in any real detail, the information on fax is extremely sparse (this is what I work on, BTW) and the writing style gave me a headache after the first 20 pages. I agree 100% with the reviewer who said that someone needs to write a good Cisco VOIP book. This book isn't it. I bought this book based on the earlier reviewers' glowing comments and was VERY disappointed ... maybe they were reviewing a different book. This is is absolute garbage.
