-----------------------------------

    Resolution: Not A Bug

So, [~jcolp] looked over this issue with me. This doesn't appear to be an issue within Asterisk.

I'd recommend verifying that you have the very latest libsrtp version and if the crash happens again be sure you get libsrtp debug symbols for the trace. File it with the libsrtp project at that time.

Otherwise we can't do much investigation here without being able to reproduce the issue.
