Amateur programmer here but I want to try to attempt to look through the ‘C’ codes. Could someone direct in the right direction. Where is the module for file of ‘fax_detect’ which the bool is usually located in pjsip.conf.
I want to see the frequency that asterisk is listening on. From my understanding fax incoming generates a freq tone on 1100 hz but when trying to detect fax on outgoing, it generate a tone of 2100 hz correct me if im wrong so I was wondering if I can edit the AMD function and add additional parameters to the function to listen on outgoing/incoming fax tone within dialplan.
