Hi all,

I'm currently generating dial out using "ESL with python" and the originate command.

Since some dial out calls are fax I need to classify which of these calls are fax, otherwise I record the ones which are normally answered.

I'm trying to use:

execute_on_fax_detect

As follows:

originate {ignore_early_media=true,originate_timeout=20,media_bug_answer_req=True,origination_uuid=4cb6665a-1e2a-4e24-ad71-1602870960d2,origination_caller_id_number=+18623079305,RECORD_STEREO=true,execute_on_fax_detect='txfax /tmp/sample.tif',execute_on_answer='record_session /usr/local/freeswitch/recordings/E6248DD147_8884732963_4ab6665f-1e2a-4e24-ab71-1602870960d2.wav'}sofia/gateway/twilio/+13193412303 &park()

Call is answered but I don't see any fax detection kicking in.

I also tried with +18884732963 which is the HP test fax number.

In the recording I can hear the Fax tones.

FreeSWITCH (Version 1.7.0 git c9abf45 2016-06-27 22:23:25Z 64bit) is ready

Topology:

python --- ESL --> Freeswitch -- sip-- Twilio ---> PSTN ---> fax

When I use:

originate loopback/9178 &txfax(/tmp/surface3d.tiff)

I do see Fax modules being invoked:

Thank you
