Hi

I was hoping someone could help me to setup the fax detection / tone
detection application.

I want to be able to transfer an incoming fax to a specific extension.
In my default.xml file, I have the following (extracted):

<extension name="1000">
<condition field="destination_number" expression="^(10[01][0-9])$">
<action application="fax_detect"/>
<action application="tone_detect" data="fax 1100 r +5000
transfer fax XML features" />

I can't get the fax to be detected and transferred. Is there any way
this can be done?

Thanks!

check out http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_tone_detect

Note, you can't just have tone_detect as your last iten in the
dialplan as the call will just get hung up.

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!

Fax tones are not played by the remote machine until after answer, the
tone_detect application starts a media bug that listens for the tone,
can you confirm the tone is happening at all. Maybe the issue here is
the timeout, try making that longer, or doing the tone_detect in
execute_on_answer

hi Mark,

This is an inbound call leg and media channel (so far)  is open in reverse direction only (application ringback). I'm afraid you have to answer the call to be able to "hear" the fax tone.

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!

Further playing around and everything is working fine (even the
emailing). I'm not sure what I changed though to document it.

cheers

<action application="set" data="api_hangup_hook=system ${syscmd}"/>
