Great read
When i got into VOIP sales i couldn't even tell you what VOIP was. This book is a must read for anyone who is interested i VOIP. The author does a great job in dumbing it done in the beginning so you understand what he is talking about. This book saved my life.

Engineers and Manufacturers should read this before selling messed up VoIP phone systems.
I bought this book after taking a job with a company that seemed to be screwing up VoIP telephony every step of the way. This book confirmed this. With many highlights and dog eared pages, I placed this on my bookshelf at work. When co-workers said something stupid, I referred to this book for additional credibility on what I was saying to them.Great overview of voice over IP. It is not only a Cisco pandering book like many are. It mentiones SIP and open source methods. Many common basic pitfalls and solutions are discussed. This is a perfect book to read for a small business or group to use before buying hardware or being sold a service or product. It is written in generic form so any vendors products and services can be understood before wasting time, money and effort.Do not buy a MAX Call-Taking VoIP telephone system for a 9-1-1 call center before buying this book. Those that have, are living with the problems that could have been avoided if engineers read the basics of VoIP telephony before making such a horrible product.

Not technical and very dated
This book was written in 2005 and it really shows. A significant amount of the book revolved around justifying the cost of your VOIP integration by removing Intralata costs. :-). The list of top 10 VOIP providers is full of companies who've gone belly up (RIP Nortel) or merged with each other (Mitel /Shortel). Many of today's big players (Ring Central, 5Nine, Vonage,8x8 etc) never get mentioned.It's also designed for business folks. The topic of jitter gets literally 5 sentences, in the entire book. Dated concepts like Centrex and KTS are covered much more fully. The technical information that is in here is mostly filler, like coverage of the TCP Networking model.And that's a shame, with an update this could be a great and much needed book, but until version 2.0 is released leave this one on the shelf.

VoIP for Dummies by Avaya and outdated
This may have been relevant in last decade, or century. Also, I had read the AVaya hype years ago. Had I known this was written by and promoting Avaya, I never would have ordered it.

VERY High Level Stuff
This book isn't for technical people looking to implement a VoIP solution. It doesn't even define the terms one typically finds in eBay auction descriptions. For example, a typical description for a VoIP phone contains statements like:- Support popular vocoders including G.723.1 (5.3K/6.3K), G.729A/B, G.711 (a-law and u-law), G.726, G.728, and wide-band G.722 (Model 102D).- Support Silence Suppression, VAD (Voice Activity Detection), CNG (Comfort Noise Generation), Line Echo Cancellation (G.168), and AGC (Automatic Gain Control)There is no introduction to this terminology in the book. Only a few paragraphs on SIP and nothing on H.323, SCCP, or IAX. Nothing about setting up gateways or servers. No mention of Asterisk or Digium cards or Skype.According to the back cover the author is a business professor which is likely the reason for the lack of technical material. I get the impression he is well-versed in traditional telephony systems but his actual hands-on experience with VoIP systems is very limited if it exists at all.
