Summary: Excellent introductory
Review: Anyone who has no knowledge about telephony can gain a good grasp about the subject by reading this book. But if you are looking for trite technical treatment on the subject this one is not for you, since this one is written for those with no backgorund at all.

Summary: Ip Telephony
Review: I am a college professor as well as VoIP instructor and must stay current with technology for my students. I frequently have numerous books that are sent for my review, as this one was, and of all I have recently read, this book is by far my favorite. It is well written and gives the reader two perspectives- a telephony point-of-view along with a data point-of-view. Well worth the price....Greg J. Hauser

Summary: A good one for new ones on IP telephony
Review: I think that for those of us non familiar with IP Telephony is a good introduction. As all the network/ip stuff you have to read a lot from other sources to have the complete scope. If you plan to learn from zero you are on the wrong place

Summary: Who is the target audience?
Review: In his desire to attract as many readers as possible, the author got carried away with verbose explanations of sometimes unrelated matters. I failed to imagine a typical reader of the book: there are chapters for those completely unaware of digital telephony and packet data. So the book is more a mediocre manual on telecoms in general best fit for a freshman of business administration. I would also think that a telecom regulator could find useful a chapter or two, but for that kind of person I would recommend getting a first-hand, free-of-charge experience by visiting corresponding pages of an ITU website.

Summary: Awful, just awful
Review: The author has a tendency to go on tangents, such as describing for a full page how globalization has swept the economy, or the history of the PC leading up to the advent of the internet. He spends more time justifying technologies than showing their merit.
Rating: 
Summary: Waste of money
Review: This book is way too detailed in some chapters, and way too superficial in others. It's also very repetitive, so it's a pain to read.

Summary: Excellent introduction to IP Telephony
Review: This book provides a well-written introduction to IP Telephony. It includes a wealth of background information, understandable explanations, and is sprinkled throughout with interesting anecdotes. I recommend it without reservation to anyone seeking a basic understanding of this technology.
