IP Phone Administrator Guide

When a phone receives a request for receiving RTP:

•

if there is an existing audio path, (handset, headset, or speakerphone), the 
phone uses it to play the incoming RTP stream on top of the existing one.

•

if the phone is already in a 3-way conference, the request is declined.

•

if there is no existing audio path, the phone creates a new one (speakerphone) 
to play the incoming RTP stream
