Intercom calls made by the originating caller.

answer an Intercom call. If auto-answer is enabled on the IP phone,
the phone plays a tone (if "Play Warning Tone" is enabled) to alert
the user before answering the intercom call. If auto-answer is
disabled, the phone rejects the incoming intercom call and sends a
busy signal to the caller.
Allows you to enable or disable a warning tone to play when the
phone receives an incoming intercom call on an active line.
Allows you to enable or disable how the phone handles incoming
intercom calls while the phone is on an active call.
