[Freeswitch-users] Why I could not detect DTMF when using Originate command

[Michael Lutz]

If your outbound provider does not support RFC2833 (DTMF via SIP Info
messages) you need to explicitly set the outbound leg to 'listen' for
DTMF tones using the start_dtmf dialplan command.
As you originate, there is no real dialplan, you can set it using the
"execute_on_answer"in inside the originate command like:

originate {execute_on_answer=start_dtmf,ignore_early_media=true}sofia/gateway/trunk_1/0860216060
8888


Regards,
Mike.
