[Freeswitch-users] Detecting a fax

[Mark Campbell-Smith]

Thanks for your help Mike and Tihomir.

A little more playing around and I found that having <action
application="fax_detect"/> as well as <action
application="tone_detect" data="fax 1100 r +5000 transfer fax XML
features" /> do not work together.

Simply by removing fax_detect, the fax is detected beautifully.

My problem now is trying to email the fax.  I followed the
instructions on the wiki at http://wiki.freeswitch.org/wiki/Mod_fax,
but the dialplan <action application="system" .../> is not executed
after the rxfax command.  I know the script works because if I put the
system command in another part of the dialplan and hard code the
filename to attach, then the email is sent.

    <extension name="receivefax">
      <condition field="destination_number" expression="^receivefax$">
        <action application="answer" />
        <action application="playback" data="silence_stream://2000"/>
        <action application="rxfax"
data="//usr//local//freeswitch//storage//${caller_id_number}-${uuid}.rxfax.tiff"/>
        <action application="system"
data="/usr/local/freeswitch/scripts/emailfax.sh
/usr/local/freeswitch/storage/${caller_id_number}-${uuid}.rxfax.tiff"/>
        <action application="hangup"/>
      </condition>
    </extension>

ideas?
Thanks!
