Summary:                    [patch] session-expires default timer wrong
Description: 
There is a bug in chan_sip which causes asterisk to set invalid
session-expires-header in 200 OK after invites. My guess is that it's been
there for a long time but got activated with bugfix 15403. 

The problem is, that for invites without session-expires-headers a reply
is generated with Session-Expires: -1;refresher=uas causing the uac to
hangup the call with BYE immediately. 

A workaround is setting session-timers=refuse in sip.conf
