Hi, I'm building an application that interfaces with FreeSWITCH through mod_erlang_event. For inbound calls (where a user dials my extension) everything works the way I expect. Unfortunately for outbound calls somehow my DTMF events are not coming through. It seems I'm not the first one to experience this issue, but the solutions I find online do not seem to fix the problem for me. This is what my basic originate command looks like (through mod_erlang_event): {foo, freeswitch@fsdev} ! {api, originate, "{origination_caller_id_number=123456,Paddy-Survey=monitoring,Paddy-Question=intro1}user/1003 123456 XML default 1003 1003"}. Based on solutions online I've experimented with adding execute_after_bridge_app=start_dtmf, execute_on_answer=start_dtmf, dtmf_type=info and drop_dtmf=false to the channel variables but none of those seem to help. (The origination caller ID and Paddy-* variables come through as expected so the variables seem to get set.) I've also tried sending the start_dtmf command from my application after answer, I see the command getting executed in the FreeSWITCH log but it doesn't change the behavior (DTMF still doesn't come through). Finally I've tried calling {foo, freeswitch@fsdev} ! {api, uuid_broadcast, CallUUID ++ " start_dtmf"}. after I answer <http://freeswitch-users.2379917.n2.nabble.com/Why-I-could-not-detect-DTMF-when-using-Originate-command-td7576047.html>, but this gives me an error 2019-12-10 10:57:18.540690 [ERR] mod_native_file.c:74 Error opening /usr/share/freeswitch/sounds/en/us/callie/start_dtmf.PCMA 2019-12-10 10:57:18.540690 [ERR] mod_sndfile.c:204 Error Opening File [/usr/share/freeswitch/sounds/en/us/callie/start_dtmf.wav] [System error : No such file or directory.] Any suggestions on how I can get my outbound calls to work the same way as my inbound calls? Kind regards, Sam
