I have the same problem, Switched to
HylaFax and IAXModem and had MUCH better luck. MUCH better being defined as not
a single usable fax to only missing about 1%. Not bad.
Spandsp or rather RXFax works on a few
machines I hae quite well but on others it does not work at all, I have had
good retruns with the HylaFax.IAXmodem combo on machines that could not use the
RxFax.

Subject: Re: [Asterisk-Users] FAX
over PRI
I have had nothing but
problems receiving faxes over PRIs with spandsp. I currently have 4
systems, 4 PRIs from 4 different providers... none of them get better than 50%
success rates receiving faxes in spandsp, I constantly get cut off pages.
No body seems to have a fix for it, and it is really frustrating. Supposedly
it is caused by "frame slips" on the PRI, but if that is the case, I
am 4 for 4 getting crappy PRIs that can't keep time.
These same boxes work fine when receiving faxes over fxo ports, or if I plug a
fax machine into an fxs port and call in to a spandsp extension the fax will be
received just fine, so I am left thinking it must be the PRIs, but if all PRIs
are this bad, how can anybody be using them?

Sorry for the late reply but both of these are fine, we use spandsp to
print some faxes and email others.
We also route via a PRI to our other phone system to hylafax on an
analog modem and also to an analog fax.
So what you want to do is fine and will work.

Hmmm, Im not so sure I can apply this to me though. I just want to
do
Fax-To-Email using PRI channels as the incoming lines. Not so much
transfer
to a real fax.
I am assuming that this is easily done with Asterisk? (I did it before
with
Asterisk SIP, but it only worked once every 10 tries or so)

I'm having good success doing fax over PRI using a TE405; one span to
the
PRI, the other to an FXS channel bank that is almost obscenely
underutilized
(3 channels).
I also have channel bank - T100P - IAX2 - TE405 - PRI, where the IAX2
link
is a 1-hop SDSL (VOIP only) data link. This works well too.
