[Freeswitch-users] Detecting and blocking fax calls

[Ali Pey]

You can use something like this:

<action application="set" data="execute_on_answer=spandsp_start_fax_detect
transfer 'fax XML default' 5"/>

The chances are that some faxes won't get detected but I have never heard
that regular phone calls would go to fax.
