Summary:                    Revision 202007 Introduces Deadlock
Description: 
After upgrading from 1.6.0-beta9 to 1.6.2-rc2, we are experiencing
deadlocks in try_suggested_sip_codec().  "core show locks" points to code
introduced in revision 202007, which ironically was intended to protect
against deadlocks.  The Asterisk build is completely stock except for a
modified SIP response code in chan_sip.c:handle_request_invite().

We have had two deadlocks so far in as many weeks, both times during
periods of lower than average call load.
