The early chapters give a good grounding in networking and IP. Voice coding is covered and is clear. A little to much emphasis on outdated protocols and the history behind the evolution of data transportation methods. Good references are made to the ITU standards, the Internet Engineering Task Force (IETF) and similar bodies. These provide a good link for further reading and investigation.

I bought it, read it and I was really dissapointed. If you want to have a deeper knowledge in Voice over Ip maybe this book will not help you.

I got this book at Interop as part of a package, attending Professor Held's lecture they gave me the book. The book is really good, it covers IP and Frame Relay, telephonre operations and shows how to transport voice over both. It even includes examples of economic analysis that I found extremely usefull as I had to do this to get my project approved. The only area where improvement is required is that Professor Held's lecture included many practical application notes concerning latency that were not in the book. By the way, he provides his email address and responds to requests, so he might provide you with this usefull information.
