err that wasn’t quite what I asked. My fault, I didn’t really go into enough detail. Let me start again.
I’m running Asterisk on a dedicated Ubuntu server box. I have two incoming SIP trunks from sipgate, and a half-dozen SIP handsets. It all works well and I’m very pleased with the setup.
Next step is to be able to receive incoming faxes. I have an HP3030 all-in-one which is already connected to the POTS line (and not talking to Asterisk at all at this point), so I can send faxes OK. But receiving them is a problem as I only have one POTS line and would very much like a dedicated fax number. I have earmarked one of my sipgate trunks for this purpose. I’ve tried and tried to get FFA working as this would be ideal - just have it receive the incoming fax, save it as a PDF and email to me. Unfortunately I just can’t get FFA to install. See viewtopic.php?f=28&t=71524 for details.
So I’m exploring the next idea, which is to take a call on the dedicated incoming-fax SIP line and route it through a SIP-to-Analogue device to the fax machine itself, hoping that said fax machine just answers the call and receives the fax as though it was a normal POTS fax call. Yes, this is very much the long way round!
