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

[Michael Lutz]

Hi Michael,

Can you explain a bit more? If you would initiate an outbound call
using an originate api call, there is only one leg? How would you
specify to listen to the b-leg, other than this?


It might explain some issues I have recognizing (valid) dtmf's...

Regards,
Mike.
