Understanding Sip Servlets 1.1
Despite the similarity to HTTP, SIP can be a difficult technology
to understand. It is asynchronous, peer to peer and often many
parties and protocols are involved, making it a daunting topic.
There have been few attempts to demystify but none that deal with
the topics head on, from a developer perspective. Chris Boulton and
Kristoffer Gronowski have done a good job simplifying concepts and
presenting them in an engaging and practical way.
The first half of the book explains SIP concepts, the container
role and application programming model. Similarity and differences
from Http Servlets are explained. Application composition in SIP is
quite different from web, a single SIP request may be seen by
multiple applications (this is how you get call filtering, voice
mail and call waiting!). Exactly how this works and how it can be
changed, is all explained in Chapter 4. The second half of the book
is more practical with hands-on code samples for services and
clients. Chapter 8 dives deep into the internals of SailFin, an
open source sip servlet container, in case you are looking to
extend or customize the server functionality.
Overall, the book is informal in style and readable. It walks you
through from concepts and API to developing/testing sample
services. You get the confidence to try out more stuff on your own.
It is worth reading if you planning to develop applications for the
mobile network, add voice and messaging interactions to a web site
or just want to know more about the technology that underlies
modern communications services.

This book thoroughly covers the SIP Servlet Container, the
Application Router and much more. It is easy to follow and goes way
beyond my expectations in its coverage of topics related to SIP
Servlets.
I hope these two authors pair up on more books.
