ASSESS WHAT SIP CAN DO AND DELIVER
EVALUATE SIP's FIT WITH OTHER STANDARDS AND SYSTEMS
PLAN NEW SIP-ENABLED SERVICES
The Session Initiation Protocol (SIP) is the signalling protocol that will deliver IP multimedia services for the third generation of mobile systems. It will merge together the cellular and Internet worlds. It will provide ubiquitous access to the services it enables, and make us a truly mobile population for the first time. These are not small claims, which might explain why some people have started looking to SIP as an all-purpose solution to building the telecom future.
In fact, SIP is a powerful but limited protocol, with a well-defined scope. This book describes it in the context its framers intended, and meticulously explains how to use it as a transformative tool for telecom services. Written by one of the earliest contributors to SIP development in the IETF, SIP DEMYSTIFIED takes a long look at the "what's" and "why's" of today's most talked-about protocol, helping readers to move past the buzz, get poised for 3G, and start developing tomorrow's applications.
You must read this book if
- You're a telecom engineer, manager, or developer who wants to survive professionally in a converged world
- You want a smooth transition from switched circuits to the connectionless paradigm
- You want to be first to market with SIP services
- You want to know how SIP interacts with other protocols
- You need to find out what architectures support SIP
- You have questions about QoS, security, and authentication
- You want to evaluate SIP products, such as gateways, proxy servers, application servers, SIP phones, instant messaging, and presence applications
- You're an industry analyst predicting and rating coming hot products and services
- You're a curious noncombatant who can't get enough insider details on how the newest technologies work
SIP DEMYSTIFIED gives you jargon-free explanations of the concepts that set SIP apart from other protocols and the reasons the standard was drafted so you can decide what to do with it.
The telephone network, also known as the Public Switched Telephone Network (PSTN), reaches almost every country in the world. Read the first page

Customer Reviews
This takes a little too long to get the the "meat" but from there on gives a pretty good detail of the SIP format for anyone looking at understanding the basic SIP code format.
As a fundamentals book for anyone wanting to start learning SIP programming it would be a good reference to have on the shelf. Skip the first half though.
The initial introduction is a bit too-long. I think that when you buy a book on SIP, you already know IP telephony and alikes works.
Before buying, keep in mind that the book is on SIP, generally speaking, and SIP is used on lots of places, not only on Internet/IP telephony.
The first few chapters are not about SIP but about telecom, VoIP in general and IETF process. I found that quite useful too.
After having read this book you will be able to understand RFC 3261 much better. This is a fast read, I finished this book in a day when I read it several years ago. This could also be a whirlwind refresher for someone who had once worked on SIP but now wants to brush up for a sales meeting tommorow.
