Maybe you could clean things up a bit and use an extension that sets some of these variables:<br><a href="http://wiki.freeswitch.org/wiki/Mod_spandsp#Execute_based_on_fax_session_outcome">http://wiki.freeswitch.org/wiki/Mod_spandsp#Execute_based_on_fax_session_outcome</a><br>
<br>Maybe do something like:<br><br><font face="courier new, monospace">originate {ignore_early_media=&#39;true&#39;}sofia/gateway/mygateway/<a href="tel:18005551234" value="+18005551234" target="_blank">18005551234</a></font><font face="courier new,monospace"> handle_fax</font> <br>
<br>Then create that extension:<br><span style="font-family:courier new,monospace">&lt;extension name=&quot;Handle faxes&quot;&gt;<br>  &lt;condition field=&quot;destination_number&quot; expression=&quot;^handle_fax$&quot;&gt;<br>
    &lt;action application=&quot;answer&quot;/&gt;<br>    &lt;action application=&quot;execute_on_fax_detect=txfa</span><span style="font-family:courier new,monospace">x /tmp/myfax.tif&quot;/&gt;<br>    &lt;action application=&quot;execute_on_fax_success=perl <a href="http://fax_sent.pl">fax_sent.pl</a>&quot;/&gt;<br>
    &lt;action application=&quot;execute_on_fax_failure=perl <a href="http://fax_failed.pl">fax_failed.pl</a>&quot;/&gt;<br>    &lt;action application=&quot;playback&quot; data=&quot;silence_stream://20000&quot;/&gt;<br>    &lt;action application=&quot;hangup&quot;/&gt;<br>
  &lt;/condition&gt;<br>&lt;/extension&gt;<br></span><br>Of course, do your own thing with the execute_on_fax_xxx variables. Standard disclaimer applies - test it and tinker before telling me it doesn&#39;t work. :)<br><br>

</font><br></div>You&#39;ve enabled &quot;fax detection&quot; on the call but you haven&#39;t told the call to actually do anything. From what you&#39;re doing it seems like you&#39;re wanting to detect a fax and then run the txfax application. But what happens if a fax is not detected? Also, what happens to the call in the interim, i.e. between the time you enable fax detect and the time it actually detects a fax tone? The call needs to do &quot;something&quot; while waiting for a fax tone. You may be better off sending this call to an extension and then having several dialplan actions, like &quot;answer&quot;, &quot;spandsp_start_fax_detect&quot;, and then a &quot;sleep&quot; or &quot;playback&quot; app, or something for the channel to do while it&#39;s waiting for fax tone.<br>
