I have been wanting a small free simple fax solution for incoming faxes on a voice DID. The way FFA is supposed to work with the FreePBX module would be perfect, except that fax detection is worthless... accept for one little way that I found.
I've posted at the FreePBX forum about it.
Figure I'd post here also for those looking to do the same.

What I've done is setup a dummy IVR that the call goes to first. Odd thing, if there is no join announcement, it doesn't work. So I've recorded a ringing tone and placed that as the join announcement. After that it rings the extension. I've had 100% success rate on detection.
To recap, the inbound route has detect faxes enabled. Wait time is the minimum selected (2). The fax recipient is a regular sip (voice) extension that has faxes enabled. The destination is the dummy IVR. The IVR had a ringing tone (one full ring and the dead time following - total time - just under 6 seconds). The timeout on the IVR is zero and t destination is set on the IVR to failover to the voice extension (happens to be the same extension as the fax recipient above).
Behavior is when a voice call comes in, the calling party has a slight 2 second delay before they start hearing a ring. After the first ring they hear, the extension start ringing.
When a fax comes in, it is detected in that first ring and handled appropriately.
To get the ring tone, I just set a misc application to go to terminate - ring forever then recorded the call (I put my phone on mute). I then edited the file in audacity for the length I wanted.
Hope this helps someone else.
