Incoming Intercom Call Features
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 the following
parameters using the Aastra Web UI:
• Auto Answer
• Microphone Mute
• Play Warning Tone
• Allow Barge In
Auto-Answer/Play Warning Tone
The auto-answer feature on the IP phone allows you to enable or disable automatic answering for an Intercom call. If
Auto-Answer is enabled, the phone automatically answers an incoming intercom call. If Play Warning Tone is also ena-
bled, the phone plays a tone to alert you before answering the intercom call. If Auto-Answer is disabled, the phone
treats the incoming intercom call as a normal call. Auto-Answer and Play Warning Tone are enabled by default.
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 fea-
ture. Microphone Mute is enabled by default.
Allow Barge In
You can configure whether or not the IP phone allows an incoming intercom call to interrupt an active call. The Allow
Barge In parameter controls this feature. When you enable the this parameter, which is the default value, an incoming
intercom call takes precedence over any active call, by placing the active call on hold and automatically answering the
intercom call. When you disable this parameter, and there is an active call, the phone treats an incoming intercom call
like a normal call and plays the call warning tone. Allow Barge In is enabled by default.
Note:
Your Administrator can set a time period delay before the phone automatically answers. Contact your System Admin-
istrator for more information.
