Hi Marco,<br>could you try again with different quality settings on your hardware fax?<br>I see 1728 x 540 in your spandsp log.<br>I think spandsp is only compatible with :<br><div style="margin-left: 40px;">standard: width=1728 x length=1128
<br>fine: width=1728 x length=2252<br>super-fine: width=1728 x length=4491 <br></div>which are the 3 resolution you commonly find in G3 faxes.<br>I don't know what this mode is : 1728x540.<br>Regards,<br>Pirlouwi.<br>

</a><br><br>Marco,<br><br>First off, do not use any version over 0.0.3. I am using 0.0.3 on centos<br>4.5, asterisk 1.2.24 and freepbx 2.3 and it is working very well. One<br>very important thing to keep in mind is that faxing over voip will only
<br>work reliably with ulaw or alaw and your internet connection MUST be<br>able to sustain a constant data stream with low jitter. If your<br>interested I have a shell script to install asterisk 1.2.24 and<br>freepbx-2.3
with rxfax and txfax on centos 4 and working on centos 5.<br><br>Jonn<br><br><a href="http://jonnt.users.taylortelephone.com/asterisk/centos-asterisk-install.sh" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">

</div><br></span></div>hi john,<br>thank you for your reply.<br>I've installed the configuration that you suggested (asterisk
1.2.24, spandsp 0.0.3), but with no luck: I still cannot receive faxes.<br>Please note that I am not using T38: I am receiving faxes with app_rxfax and storing them into a dir on the machine.<br>I have attached an isdn trunk to the card and I am trying to receive the faxes straight from the trunk.
