[Freeswitch-users] Detecting a fax

[Mark Campbell-Smith]

Thanks for the response Mike,

I read that page and this one (among others)
http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_fax_detect, but
I'm still lost.  This is an extract of my dialplan

    <extension name="Local">
      <condition field="destination_number" expression="^(10[01][0-9])$">
        <action application="set" data="dialed_extension=$1"/>
        <action application="export" data="dialed_extension=$1"/>
        <action application="set" data="ringback=${au-ring}"/>
        <action application="fax_detect"/>
        <action application="tone_detect" data="fax 1100 r +5000
transfer fax XML features" />
        <action application="set" data="hangup_after_bridge=true"/>
        <action application="set" data="continue_on_fail=true"/>
        <action application="bridge" data="user/${dialed_extension}@${domain}"/>

I would assume that on detecting a fax, the dialplan 'fax' is called
in context features.  This never happens.

When is the fax tone detected?   Is it while the call is ringing or
can it be detected after the call is answered?  My goal is to be able
to have the same extension for a voice and fax call.  i assume that
the fax 'tones' are standardised and the ones on the wiki are correct?
 Also, I guess this doesn't work with media bypass (which I don't
use).

Thanks!
