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

[Szeto, Steven]

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?
