font-family:Arial'>The company I'm working for is trying to use app_rxfax
to receive faxes on an Asterisk machine. Our initial tests looked very
promising, but unfortunately we've encountered some problems. We've been trying
to solve these problems for quite some time now, but we're running out of
options. So I really hope that somebody can give some help here.</span></font><o:p></o:p></p>

<div>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Basically our set-up is this: We have an Asterisk
server (version 1.2.7) with an ISDN trunk (Sangoma A104D), we've
configured asterisk to run rxfax on a specified extension. Originally we
started out with spandsp 0.0.2pre26 and the original app_rxfax for spandsp
0.0.2. Some of the faxes were coming in perfectly, but soon we noticed that
quite often there were substantial pieces of the fax missing in the resulting
tif file. </span></font><o:p></o:p></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

t30_set_supported_compressions, t30_set_supported_image_sizes,
t30_set_supported_modems and t30_set_supported_resolutions (I must confes that
I didn't really know which settings to use here, but we have tried a lot of
them).</span></font><o:p></o:p></p>

is missing large portions, or the fax isn't received at all. At the bottom
of this mail are 2 examples of the logging when it goes wrong. I really
hope that somebody can give a few pointers. Thanks in advance,</span></font><o:p></o:p></p>
