> 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.
