[Freeswitch-dev] Implicit pause during recording

All, I was thinking since there is no direct functionality for the person being recorded to pause the recording could this be done indirectly. For example if using the functionality to record only when voice is present could the audio stream be preprocessed to evaluate the dtmf where if a specific key was pressed the audio stream would no longer be passed or passed as blank to the recording functionality so an implicit pause would be created. And when the person recording wished to continue pressing a key would signal FS to pass the audio again therefore reestablishing recording to the same file? Bob
