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.

loloski: Following are some sample parameters that you can put in your
sip.conf in both your Asterisk boxes:

session-timers=originate
session-expires=120
session-minse=90
session-refresher=uas

These will cause SIP sessions to/from Asterisk to be refreshed every 60
seconds. You can disconnect ethernet (as JT suggested) or kill one or more
components abruptly while calls are active and notice that calls are
released when the next session refresh happens.
