[Freeswitch-users] bind_meta_app and bind_digit_action with inband DTMF?

[Dmitry Sytchev]

Thanks for update on bind_digit_action page! But still no luck with it.

My local profile has dtmf-type set to inband, does this setting have
any effect?
I'm trying to turn DTMF detection on with start_dtmf to convert it to
RFC2833 for external profile. Both profiles has rfc2388-pt turned on,
FS complaining that pt will not work on trascoded call when start_dtmf
is present, I think it is just an info message.

I see DTMF events on console being transcoded to RFC2833 but no action
launched when I press 500 during call.

<extension name="local2pstn">
  <condition field="destination_number" expression="^8\d\d\d+$">
  <action application="start_dtmf"/>
  <action application="bind_digit_action"
data="myrealm,500,exec:playback,en/us/callie/ivr/ivr-welcome_to_freeswitch.wav"/>
  <action application="digit_action_set_realm" data="myrealm"/>
  <action application="bridge"
data="sofia/gateway/mediant_2/${destination_number}"/>

</condition>
