Summary:                    [patch] fix SIP indicate deadlocks when lots of
state changes
Description: 
Running 1.8.2-rc1 and was able to deadlock several times during failed SIP
state change indications.  Found by testing 4 SIP phones in close proximity
and rapidly, yet manually, transferring blind, parking calls, picking them
up at another phone, etc.  Also, was using the Bridge() app for buddy
pickup purposes.
