If Asterisk uses incoming voice frames as a timer to send it's own voice frames, does this preclude asterisk servers ever sending audio to each other? Who would start? :)

But AFAIK Asterisk does not support silence suppression. If you remove that asterisk may stop sending sound, because it seems it uses the incoming voice frames (including silence frames) as timer to send its own sound frames. Plase correct me if im wrong.
