If you really are concerned, transfer to an ivr that says, if you are not a fax press 1, waits 10 sec then hangs up. Then the one time in a thousand when its a false detection, they can recover themselves. On Fri, Nov 29, 2013 at 9:41 PM, Ali Pey <alipey@gmail.com> wrote:
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.

We receive an inordinate amount of spam fax calls to FreeSwitch that we do not need to handle for any reason. I came across this method, https://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_fax_detect, to hopefully detect and drop these calls. Is there any danger of this method mistaking any live calls and dropping those on accident or is there a better method to accomplish this? Thanks in advance.
