    Did something change in this library on your system? What version of it are you running?
    If you disable SRTP, do you continue to have issues?
    What phone model is calling in that causes the crash? What is the relevant portion of the dialplan?
    Can you provide a pcap with RTP/RTCP/SIP leading up to the crash?

We still would like to know:

1. What version of it (libsrtp) are you running?

2. If you disable SRTP, do you continue to have issues?

3. Can you provide a pcap with RTP/RTCP/SIP leading up to the crash?

For 3. you can Google guides or tutorials on using the Linux tcpdump command or the wireshark application to gather the necessary pcaps. Basically use either of the tools to capture all traffic on the appropriate ports and to/from the appropriate hosts.

> Installed asterisk from source and it worked perfectly for days, then today it suddenly stopped working. I can start the Asterisk service and as soon as a call is attempted it crashes / segfaults and does a core dump if run with that option to do a core dump.
> Only message in /var/log/... is in the syslog:
