there is a specific app for fax detecting inside mod spandsp called spandsp_start_fax_detect it takes about the same input args namely <app> [<arg>][ <timeout>] It uses the official fax identification code inside spandsp and works much better than the single tone detect way.

If you need multiple tone detects then definitely use the first method. I've done as many as 6 tone_detects on a single call and it works well. -MC

I am trying to get tone detection set up so that a single number can be used for both voice and fax. Tone detection needs to run concurrent to the normal call processing, so that a call proceeds normally unless the fax tones are heard.
On this wiki page (http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_fax_detect) it gives the format:
<action application="tone_detect" data="fax 1100 r +5000 transfer fax XML default" />
and an associated dialplan entry for the call to be transfered to that actually handles the fax reception.
On this wiki page (http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_tone_detect) it says that the format from the first page is not the preferred method, and that the format should be something like:
<action application="set" data="execute_on_tone_detect=transfer fax XML default"/> <action application="set" data="tone_detect_hits=1"/> <action application="set" data="execute_on_media=tone_detect mytone 1100 r +5000"/>
My question is, using the first format, I could set up multiple detections, eg. one for fax tones that sends/receives a fax, one for answering machines tone that hangs up, etc.
Is this possible with the preferred syntax?
