Alexei Gradinari updated ASTERISK-28811:
----------------------------------------

    Attachment: crash2-sip-trace.txt
                crash2-backtrace.txt
                crash1-sip-trace.txt
                crash1-backtrace.txt

We observed the same or related crashes with 2 different types off-nominal re-negotiation.

1. 491 Another INVITE transaction in progress
files: crash1-sip-trace.txt, crash1-backtrace.txt

2. 488 Not Acceptable Here
files: crash2-sip-trace.txt, crash2-backtrace.txt

All files were edited to remove private information about ip-addresses, usernames and caller ids, so the length values are incorrect.

> 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.
