A comparison wouldn't be complete without mentioning Hylafax. Hylafax has a

Neither spandsp or the Digium FAX code can match that for FAX termination. I
think its biggest drawback is you either use it with iaxmodem for audio FAXing,
or t38modem for T.38 FAXing. It can't smoothly integrate the two right now.
As a longtime Hylafax user, I can confirm it's an excellent solution. I am
somewhat surprised about the comment of being able to do audio or t.38, but not
both. This is probably a little true and untrue at the same time, though I have
never used t.38modem with Hylafax.
Given the structure of the product, you could have HylaFAX connected to both an
IAXModem and a T.38Modem at the same time (or 23 IAXModems, a 24-port T1/E1
PCI-card modem, and 7 t.38modems for that matter...). What it cannot do, is
receive audio and t.38 on the same port, which is what I presume that Steve was
referring to. This is really a limitation of IAXmodem and t.38modem, as one
only handles audio, the other only handles t.38.
In other words, you could route t.38 faxes to it on port 1 and audio faxes on
port2, but you cannot have port 1 handle both types.
Its easy to set up some t38modem channels and some iaxmodem channels for
receiving FAXes. Transmit is more problematic. With this split config,
you need to know in advance whether the particular number is accessible
by T.38 or by audio. Most people won't.
