[Freeswitch-users] Faxing via FreeSWITCH documentation

[Brian Foster]

Disclaimer: Faxing over VoIP can be a crapshoot. It's very dependent on
network conditions and carrier support and implementation.

With that out of the way, the best place to start doing fax using your FS
machine (only) would be here:

Place this in your public context (maybe it shouldn't stay there, but this
is an extremely easy way to mess around with faxing):

<extension name="fax_receive">
  <condition field="context" expression="public"/>
  <condition field="destination_number" expression="^9978$">
    <action application="answer"/>
    <action application="playback" data="silence_stream://2000"/>
    <action application="set" data="fax_enable_t38_request=true"/>
    <action application="set" data="fax_enable_t38=true"/>
    <action application="rxfax" data="/tmp/FAX-${uuid}.tif"/>
    <action application="hangup"/>
  </condition>
</extension>

If you want to run a script after the fax is recieved, put this line in
before the "rxfax":

    <action application="set" data="api_hangup_hook=system <scriptname>
<arg1> <arg2> <argN>"/>

Start with receiving faxes, and go from there. Sending faxes requires some
extra work, but not much. For more information about faxing, please visit

Obviously if you have any questions, please do not hesitate to ask!
