It shouldn't be hard to do with a small lua script with an input
callback handling DTMFs.

You could even create a small DTMF editor with a digit for "backspace"
character for example, that would erase the last digit, or a digit that
would say the current sequence....

Nice!

i wrote a small script:

function onInput(s, type, obj)
   if (type == "dtmf") then
      freeswitch.consoleLog("info", "DTMF Digit: " .. obj.digit .. "\n");
      freeswitch.consoleLog("info", "DTMF Duration: " .. obj.duration .. "\n");
      if (obj.duration > 2000) then
        freeswitch.consoleLog("info", "we got long DTMF \n");
      end
   end
end

session:answer();
session:setInputCallback("onInput");
session:sleep(200);

while (session:ready() == true) do
   session:sleep(100);
end

i run it in dialplan as:

<include>
<extension name="longPound">
    <condition field="destination_number" expression="^pound$">
      <action application="lua" data="Pound.lua"/>

      <action application="playback" data="bla1"/>
      <action application="playback" data="bla2"/>
      <action application="playback" data="bla3"/>

      
    </condition>
</extension>
</include>

but it seems the lua scripts is blocking .... i never get to playback part. I need to make it run in background for the entire duration of the session

how can i do it?
