Re: Are there any design documents about sip-protocol design and implementation?

Hi Jerry,

You could have a look at the sections explaining the
implementation of
the protocol provider service:

An implementation tutorial:
http://www.sip-communicator.org/i
ndex.php/Documentation/HowToImplementProtocols

and a more generic explanation:
http://www.sip-communicator.org/index.php/Docume
ntation/PPBasics

The SIP Protocol provider is an implementation of this
service so
understanding the PP concepts would help you understand the
implementation.

It would probably also help to read through documentation of
the JAIN
SIP RI project:

http://jain-sip.dev.java
.net

The code includes tons of easy to understand examples.

Once you figure these two (i.e. pp service concepts and
jain-sip),
understanding the sip provider implementation would be a
piece of cake.

Cheers
Emil
