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

[Michael Lutz]

Ok, but with if I do an originate with a &(park) and bridge the calls
later using the api bridge command using ESL.

When I want to listen to the DTMF's generated by the originated
(called) number, I shoul use {execute_on_answer=start_dtmf, ..}
or do I need to specify the 'b-leg' and if so, how?

Regards,
Mike.
