I've got an interesting situation where I am running Asterisk 1.2.10 with
the chan_sccp2 implementation. The system crashes periodically, and each
time I get similar looking results when using gdb on the core files.
It looks almost as if someone is transferring a call to someone's voicemail
and the transferree decides not to leave a message and hangs up. Anyone
better able to make sense of the gdb bt full's and maybe point me in a
direction for resolution?
Unfortunately, I have to utilize SCCP as we are using 7960's and need
presence support which is impossible with the SIP image.
I would consider moving to Asterisk 1.4 if the skinny support where any
better, but I don't have any evidence that it is. Can anyone comment on the
native skinny support in 1.4?
My gdp bt full's are here. Thanks.
