[Freeswitch-users] How to detect DTMF and generate an event?

[Michael Collins]

I believe bind_digit_action (BDA) will do what you need. I think the trick
for you is to specify the detection leg and the action leg, that is, where
does BDA listen for a DTMF (self, peer, both) and where does it execute the
action (again on self, peer, or both).

There are some examples here:
https://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_bind_digit_action

However, I recommend you set up some simple call bridges where you
explicitly set the detect and event action legs differently so that you can
see it first hand. Once you have it working in simple cases, like pressing
a digit executing a dp app log, then you can move on to more interesting
endeavors. It's been a while, but I recall doing stuff like setting various
targets on various legs that printed log lines to the console, kinda like,
"Hey, this should be on the b-leg! UUID is '${uuid}'"

Let us know how it goes.
