[Freeswitch-users] help with wait_for_silence

[Michael Collins]

What are you using to do the recording of the audio? The record app has
built-in silence detection. If you are using record_session then I can see
your dilemma. It's almost as if you'd need "execute_on_silence" as opposed
to wait_for_silence.

Anyone out there have any suggestions for Hector on how to do this?
