As Michael suggested, I have tried the bind_digit_action application. To display a DTMF keystroke in the logs, I added this action to my dial plan: <action application="bind_digit_action" data="my_digits,~^\d+,exec:log,INFO DTMF digits detected ${last_matching_digits};;my UUID is ${uuid}"/> I get logs that look like this: Info: 2014-Oct-20 13:55:01.250 Received Freeswitch EventName: [[LOG, INFO DTMF digits detected ;;my UUID is 6b29cba9-64e4-481d-af56-7a218714d460]] - CallId: [6b29cba9-64e4-481d-af56-7a218714d460] () Notice that the ${last_matching_digits} variable is always blank. Is there another variable that I can use to display the detected DTMF digits? Is this a bug that needs to be raised & fixed?

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.

If I establish a call between two registered endpoints, and then press a DTMF key, I can see a DTMF key press event from the originator's call id:
Freeswitch EventName: [[EVENT-NAME, DTMF]] - CallId: [694eb613-6b97-4197-a951-5288066ffbf5] ()
GenerateDTMFEvent - CallID: [694eb613-6b97-4197-a951-5288066ffbf5] - TimeStamp: [10/17/2014 01:03:34.993 AM] - DTMF: [5] ()
How can I get equivalent DTMF events on the terminator's call id? I hear the DTMF key on the phone, but I need to process the keystroke in my own application.
Can the bind_digit_action application do what I need? If so, can I please get an example?
