I have not been able to pin point exactly what event causes the
freeze-up but I have been on the console when it has happened.  It
didn't print out anything interesting.  The call I was on cut off.

Same here except I would say more like 1 out of 100 calls.

I definitely have this problem.

What is your "SIP Server" what does it do?  Maybe I have the same issue
with my Cisco Voice Gateway not sending the BYE message sometimes.  But
would this cause asterisk to freeze?


Other "symptoms" I have are these errors in the asterisk messages log
file
