My Fax machine sits there as says what’s this rubbish coming in and hangs up (Brother MFC885CW) my VoIP lines are running through a Linksys SPA 2102 to a Aria 24 Pabx.
If people fax to my 2Talk fax number there is no problem. I have set up the 2102 to what 2Talk say is the best for Faxing but it made no difference. BTW I can send faxes using the Brother to anywhere in the world (over any of my VoIP lines) and I have had no problem. I just cannot receive any faxes
Cheers
