[Asterisk-Users] spandsp and app_rxfax (alternative topic:t38modem)

[Jeff]

I have the same problem and thought I would wait for someone else to post...
(just kidding Ryan)

I have used an analog trunk (FXO) AND a station (FXS) both on the same card.
I thought that it might be related to the hardware so I hooked up an old
Brother Intellifax 9000 on the station port. Both of these attempts had the
same problem.

It is my speculation that the 'cutoff' problem was related to some type of
'line noise' and that others successfully using the spandsp code _might_ be
using T1/E1 rather than analog lines (1FL) but when I started testing using
an old Fax machine plugged into a station port with a six foot RJ11 on
either end, I realized that this setup really shouldn't be introducing much
noise (if any) so I am lost. It happens approximately half way through EVERY
fax I attempt regardless of sending machine (I tried Dialogic and some
modems) or port (FXO or FXS) so I just gave up on it.

(It should be noted that Asterisk 1.0.3 runs on FC3 with
libtiff-3.6.1-8.fc3/kernel-2.6.9-1.724_FC3 otherwise)

There IS a link (search spandsp cutoff fax on Google) to a similar problem
that was apparently fixed with version 0.0.1(h). I assumed that the fix was
already applied to the 0.0.2pre6 version.

I thought I would wait until another version of either * OR spandsp was
posted but if anyone else has any suggestions (or can corroborate the
Digital vs. Analog theory) I would love to hear from them otherwise I will
test this on another PC when I get the chance.

Just thought I would chime in ....;-)
