Kevin Harwell commented on ASTERISK-28811:
------------------------------------------

[~vasilevalex], could you attach your pjsip.conf file, or at least the endpoint configurations for the involved parties, along with the relevant dialplan. Also please attach an Asterisk debug log with SIP tracing enabled [1] of a good run of the scenario (one where Asterisk does not crash), and if possible (although might be hard due to the sporadic nature of the problem) similar logging for when a bad run (where Asterisk does crash).

Thanks!

> During sending fax from Cisco SPA112 device through several Asterisk servers, latest updated server is crashed (Asterisk 16.9.0). But we can't reproduce crash, as sometimes faxes send fine, from other Cisco SPA112 devices faxes just stopped sending (receiving works fine). After downgrade to 16.8.0 everything works fine again.
