Note

audio and video streams.

and Direct Transfer Policy to disable join and direct transfer on the same line or possibly
across lines.
Allows users to combine two calls that are on one line to create a conference call and
remain on the call.

voice-message system uses the specified directory number to set or to clear a message
waiting indication for a particular Cisco IP Phone.
