Asterisk 12 is now in security fix only mode and is no longer receiving bug fixes.

If you can, please re-test with the latest RC from Asterisk 13. There were a number of bug fixes related to the RTP engine/implementation, which is where your crash is occurring.

Thanks Matt. Upgraded to 13.1.1 and had another crash. Not sure if its related to the same problem, I'll post back in a few hours.

I am no longer receiving core dumps with asterisk 13.1.1 . I am still having another issue, but once I isolate it, I will open a new ticket if required.

Okay - I'll close this one out then. Thanks for reporting back!
