I am not sure if the original project integrates now a VAD for the audio switching (it was made for sure in the past in the RPT audio inactivity...).
There is a mode where you can switch the video source by pressing DTMF keys too. You cannot prompt video clips, only the audio is supported. There is a fork of app_conference called app_konference (it supports Asterisk 1.6).
