Alexey Vasilyev updated ASTERISK-28811:
---------------------------------------

    Attachment: pbx-fax.txt
                cisco-pbx.txt

I attached SIP traces, that were made, when Asterisk 16.9.0 was running and later we had the crash. cisco-pbx.txt - SIP call from Cisco SPA112 to first Asterisk server (pbx1) in the chain. Then the call goes to Asterisk 16.9.0, then to another pbx2 and then to fax-server. pbx-fax is SIP trace for the same call, but for the last leg. I don't know if it can help - but all these calls were failed, Cisco could not send fax. When we downgraded server in the middle to 16.8.0. all the faxes start working again. And it looks, like the similar call crashed 16.9.0

> 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.
