Summary:                    [patch] SIP Session-Timers Support in Asterisk
Description: 
The Asterisk SIP stack currently does not support SIP Session-Timers (RFC
4028). This leads to defunct SIP sessions in Asterisk when calls do not
clear through normal signaling procedures due to network or end-point
failures.

John Todd recently discussed this concept on asterisk-dev:
http://lists.digium.com/pipermail/asterisk-dev/2007-July/028574.html

John Todd, JR Richardson and Kevin Fleming have expressed interest in
seeing this feature supported in Asterisk.

A software design document for this feature and code changes (unified diff
of chan_sip.c) are attached to this report. Digium has my code submission
agreement on file.

Ran into a minor bug when testing with Windows Messenger (a SIP end-point).
We were calling start_session_timer() when the UAS does not support
session-timers and we were configured in the "accept" mode. The fix for
this issue has been uploaded as chan_sip.c.diff. 

Also uploaded is sip.conf.sample.diff that explains Session-Timers config
params.

Both diff files are based on the following trunk:
