[Freeswitch-users] Dialplan/PHP esl variable problem.

[Anthony Minessale]

I think you might be twisted around its possible that doing what you
are doing is much more complicated than just using the socket app.
If you are just trying to play a file and get a digits etc you could
do it all with existing dialplan apps.
