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

    Status: Waiting for Feedback  (was: Waiting for Feedback)

This first happened in version 16.9.0. Downgrading to 16.8.0 fixed the issue. The problem happened in function sip_session_refresh() in the file /usr/lib64/asterisk/modules/res_pjsip_session.so which was significantly modified from 16.8.0 to 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.
