as usual we are alone here ...
I just lost my patience and did it directly in code!

Once rewriting according to FS requirements done , will provide a patch if anyone interested.

usage in DP:

<action application="bind_long_dtmf" data="0 a s transfer::myExtension XML myContext"/>

in myExtension you do your stuff!

Have you tried using the event socket library http://wiki.freeswitch.org/wiki/Esl

well, i could have used esl from the start but thats and external application controling FS... and its totally a different approach from where im now:(.
I have everything up & running except this feature ..

so is there any chance to run a lua script in background (by allowing the normal callflow to go on) to collect a special DTMF event ?

something like this:

<action application="set" data="api_result=${lua(script.lua)}"/>

?
