Summary:                    Abort in free() in local_hangup, possibly related to
failure to provide ringback indication
Description: 
We tried running under valgrind, but that didn't produce any obvious
indications of problems, and also made the ring back indication problem go
away, suggesting that there may be a common race condition that is causing
both.

I ran SIP history on the outgoing call and got the expected
INVITE/Trying/Ringing sequence.

gdb was only able to see the one thread.  I don't know if that is because
it was an abort(), or because memory corruption has prevented it from
finding the information about the threads.

Part of the description got lost because I let the original cookie timeout
and had to copy to a new submission form.  It should have started:

We have had a couple of crashes whilst trying to get debugging information
for a problem where SIP calls to Cisco CCM fail to provide ring back
indication, but calls to a SIP phone do.  In both cases the crash is the
result of free() issuing an abort() when called to free a local channel
private structure.
