Issues sending and receiving faxes with HT802

[qbitnetworking]

Hi there, does anyone know the trick to getting the HT802 to work with 3CX v20? I have a bunch of them deployed and they all seemed to have stopped working. I've been pushing some customers to eFax but not all of them want to do that so I really need to figure out why faxes aren't sending. I seemed to fix the issue with receiving by changing the mode from T.38 to G711 (passthrough) but the still can't send.

Did you see the call on your pbx? What does the log say?

They all basically say this when a fax comes in:

That's like nothing... Check the log at least with medium or verbose.
