OK this here is the backtrace, this crash happened when there was noone
in the office, I don't know whether there was an inbound call at the
time or not. I hope this is what you need, Let me know if you need
anything else. There does not seem to be any pattern to the crashes.
Today I was on an outbound call over CAPI ISDN for 25 minutes, during
which several other inbound, outbound calls were made, and suddenly it
crashed, ending my call. Then the crash BTed below happened when there
was noone in the office. Any help would be much appreciated, as I will
have to regretfully give up on Asterisk if I can't get a solution. If
you need the actual core dump it is at
