Gregory Massel commented on ASTERISK-28499:
-------------------------------------------

I have been able to isolate the specific calls that trigger this crash.
At some point in each of the calls (usually the very moment the remote party stops playing on-hold music and actually connects to a phone), I receive a truncated RTP packet from the remote party.
As that truncated RTP packet comes in, Asterisk SegFaults.
Unfortunately for confidentiality reasons I cannot upload an entire PCAP of the calls, however, I'm uploading a Wireshark screen-shot.

> Asterisk segfaults randomly.
> Appears to have been stable since downgrading to 13.27.1 (however, this may just be luck).
> I will attach backtraces.
