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* *Logs:* http://pastebin.com/WE4cMdaB *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: http://pastebin.com/9P2yJFWS Thank you
