Alexey Vasilyev commented on ASTERISK-28811:
--------------------------------------------

I've applied only one patch ASTERISK-28811-2.diff We have tested the same scenario. Faxes from Cisco SPA works fine now.
In the test we used the same device, and before patch we could not send any faxes at all.
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.
