Disorganized and too shallow
(2006-08-13)
This books presents SIP, the protocol for Session Initiation. It covers many aspects, including conferencing, security, Internet telephony, user preferences.
The book is not 400+ pages as Amazon indicates but just below 300. Why does this matter? Because, with 17 chapters, this gives an average of less than 20 pages per chapter. As you can guess, 20 pages are not sufficient to explain topics such as Internet telephony, or conferencing. Even the SIP protocol is not presented fully. Only the major messages are listed with a short description of their use.
I was also disappointed by the book organization. The SIP Overview chapter which explains how SIP works is chapter 5. All the preceeding chapters mention SIP before we even know what SIP is. This is most confusing unless you have already some SIP knowledge.
The book tries to cover too much. We get a whirlwind tour of many topics, none of them explained appropriately. The book opens many issues that remain unanswered. If you want a shallow overview of SIP, this book may meet your need. But you are likely to quickly need something more in-depth.

I am new to the SIP protocol and thisi book gave me exactly what i was seeking: a comprehensive explanation of the SIP architecture and the uses of SIP. The specific chapters on SIP and User Services, Security, IP telephony, DNS and QoS all provided the basics necessary to understand the tradeoffs and issues with implementing SIP.

This is a great place to start to give you perspective before you dig into the RFCs. Or if you never intend to read the RFCs, this book will give you enough of an understanding of some of the fundamental technology so that you'll be able to follow some of the deeper issues of SIP. Well written too.
