Voice Over IP Fundamentals

Very well written. I am learning quite a bit about VoIP. Highly recommend it.

The book is a very comprehensive introduction to VOIP. It is a very good beginning for anyone with either good networking or good telCo. experience. This book would also be useful for a person with a combination of some net & some telco. It is a technical read, but no so much as to be difficult to get through. A person with no true experience may find themselves a little bit out of their element and should be prepared to do some reference work.

This book is the one to read if you want to know something about the basics of Voice Over IP and the protocols which are involved like H.323. It also gives you an introduction to the POTS ( plain old telephony service ) standards. So, if you are new to VoIP and want to read about it from the ground, buy this.But it is not the right choice if you are searching for preparation material for the cisco #640-647 cvoice exam. For that exam you also have to know something about VoFR and VoATM, which is not covered deeply enough here.

Jim, Jon, and Brian have written a good informational book about the basics of voip technology. It is interesting to see where voice started and provide a clear path for where it is going. I found the configurations in the back very useful. As a note to the previous reviewer: Page 168 states that "serialization delay is not covered IN-DEPTH". If the previous reviewer continued to read the book they would have noted on page 213 and 214 a discussion on propagation delay and the need for fragmentation. Overall I found the book useful, however I would have liked more configurations.

Jon and James have a conversational writing style that was easy to follow for me. They have included a lot of historical information that should help the reader understand the momentum behind the transition that is taking place today, creating a "new-world" model of internetworking that has its own rules.As previously mentioned, this is not a design and implementation guide - the forthcoming Cisco Press title "Cisco Voice Integration" will be when it is released. This book does, however, give the reader a very detailed introduction to the underlying technologies that make Voice over IP, Voice over Frame Relay, and Voice over ATM work.The book was a good read even for someone like myself with over 12 years in telephony and networking. Jon and James have done a good job of collecting and communicating relevant information about each of the VoIP building blocks.
