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

Hello Joshua,

Yes, it is configured with --with-pjproject-bundled. Endpoints are 2 types - local (phones, softclients using TCP with local IPs in the same vlan as PBX) and external (providers trunks using UDP with public IPs). PBX itself behind NAT but ALG(cisco SIP inspect) makes all NAT work.
What console logs do you mean, full log before crash? I didn't have debug enabled but  i was connected to cmd when it happened, should i submit output of console (for how much time before crash?)?

> Hello,
> I experience random segfault crashes on Asterisk 13 setup with pjsip. Crashes happen for no apparent reason, it can be twice a day, can be once in 2 weeks. I have 2 servers with the same configuration and they both segfault from time to time. I can't reproduce this crash and don't know what is the reason. Also all endpoints that were registered before crash don't come back and register, i need to manually reboot/re-register all phones.
> I created a topic on Asterisk community and was advised to update my version since there is some issue with PJSIP using TCP protocol and if that won't help then i need to submit issue here.
