Thanks for the report! In order to maximize efficiently, there are project guidelines for how to report issues. Please read through the Asterisk Issue Guidelines [1]. After reading the guidelines, please clean up this issue so that bug marshals can more easily help you.

In particular:
1. Don't post extensive debug or logs inside the Description or Comment fields.
2. Use the Description field for a description of the issue, referencing *attached* debug with links or notes.
3. Use the Comment fields for discussion regarding the issue.
4. If you need to put a few lines of debug or logs into any field, surround the text with *noformat* tags to help us read it easily.
5. Attach files with a '.txt' extension where possible so that they can be analyzed futher by bug marshals.

Thanks!

You appear to be using a distro provided version of PJSIP (which is also used for NAT traversal in res_rtp_asterisk). The version you are using has a bug[1] where a crash can occur due to a race condition in its STUN implementation. You will either need to upgrade to at least PJSIP 2.5 on the system or use the a recent verson of Asterisk with bundled[2].
