Summary:                    [patch] Asterisk sends session-timer with "require"
after 15 minutes
Description: 
When asterisk is set to defaults in session timer handling, after 15
minutes it will send a re-invite with the "required" tag.

This will cause an asterisk server with session-timers=refuse setting to
respond with a sip 420 and disconnect the call.

According to developer documentation at
https://issues.asterisk.org/file_download.php?file_id=15454&type=bug
asterisk should NEVER send a session timer with the "require" tag even if
set to session-timers=force

This issue is easily reproduced by registering a sip client with one
asterisk, set to session-timers=refuse, and place a call to another
asterisk with default session-timers settings. After exactly 15 minutes the
call will drop.

I have included a SIP Trace of the last 30 seconds of the call.
