I have an analog fax machine that I have set up as a fax extension in 3cx. Incoming calls to the fax DID are routed to the fax and it answers but no faxes are ever sent or received. My provider is Broadvox and they moved our line to a new platform to better support faxing. Between 3cx, PAP2, and Braodvox somewhere there is a problem. Any ideas where to start? I assume to start with the pap2, but i could spend forever there if thats not the problem. Phone calls via the pap2 work fine.
