[asterisk-dev] Audiohook from to direction

[Andy Cheng]

Hi All,

I am working on manipulating sound using audiohook, and would like to know
if there is a way in finding out if the frame is from the callee or from the
caller?  I want manipulate the sound only going to the callee, and not the
way back.  Currently putting manipulation code to modify the frame will
affect both directions.

Thanks in advance
