Summary:                    Segfault on chan_sip with recording (when
retransmitting?)
Description: 
Asterisk seemed to crash randomly. So we kept it running in with the -g to
get a coredump. See aditional info for the bt and bt full.

It looks like it happens in case of a re-transmit on a channel that is
running monitor. 

Box situation:
All channels are coming in on Sangoma E1 and ran thru MixMonitor before
being handed of to a SIP Peer.
