Additional Features
Incoming Intercom Call Features
Incoming Intercom
By default, the IP phone allows incoming intercom calls to be automatically answered without
having to set up an Icom key on your phone. The phone automatically plays a warning tone when
it receives an incoming intercom call. It also mutes the microphone. If the intercom call comes into
the phone while an active call is already present, the phone puts the active call on hold and answers
the intercom call.
You can change the behavior of how the phone handles incoming intercom calls by enabling/
disabling specific parameters using the Aastra Web UI. The following table describes these
features.
Microphone Mute
You can mute or unmute the microphone on the IP phone for intercom calls made by the
originating caller. If you want to mute the intercom call, you enable this feature. If you want to
unmute (or hear the intercom call), you disable this feature. "Microphone Mute" is enabled by
default.
Incoming Intercom Features in
Aastra Web UI
Description
Microphone Mute Allows you to enable or disable the microphone on the IP
phone for Intercom calls made by the originating caller.
Auto Answer Allows you to enable or disable the IP phone to automatically
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.
Note: Your Administrator can set a time period delay before
the phone automatically answers. Contact your System
Administrator for more information.
Play Warning Tone Allows you to enable or disable a warning tone to play when
the phone receives an incoming intercom call on an active line.
Allow Barge In Allows you to enable or disable how the phone handles
incoming intercom calls while the phone is on an active call.
