<br><br>If you are using one line for fax only then you do not need to do fax detect.

Hello,<br><br>I have a rather odd problem with Asterisk detecting faxes. I have two<br>POTS lines coming into the box (TDM400P). Line 1 is for voice, Line 2<br>is fof fax. When I set them up with channel => 1-2 in zapata.conf
,<br>all is fine, but as soon as I have two channel => definitions,<br>Asterisk is unable to detect faxes. The fax line is not supposed to<br>ring local phones, so the most obvious solution was to try and split<br>the contexts. The configuration below is my current setup that works
<br>almost flawlessly. The bits that aren't working are pretty annoyances<br>that result from using single context for both lines.<br><br>With the setup the way I want it, last two lines of channel 1<br>configuration and whole channel 2 configuration in
zapata.conf would<br>be uncommented and there would be no fax detection in from-analog-zap<br>context - as per the comments in the config. As it is now, from-<br>analog-zap2 may not be giving enough time for fax detection, but I've
<br>tried variations. Generally, all it will do is keep on ringing and<br>ringing and not detecting the fax tone. I've tried turning off echo<br>cancelation and few other things with no luck.<br><br>Is this possible bug in chan_zap or something related? Is there any
<br>way I can debug more? From just looking at the console it looks like<br>a regular incoming call that keeps ringing and falling though. Any<br>ideas or recommendations?<br><br>Thanks,<br>mayo<br><br><br><br>The setup is as follows:
