Receiving RTP

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

The following scenarios assume that a request for receiving mixed RTP is initiated.
