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 parame-
ters 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 fea-
ture. "Microphone Mute" is enabled by default.

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
enabled, the phone plays a tone to alert you 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. "Auto-Answer" and "Play Warning Tone" are
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.

the phone rejects the incoming intercom call and sends a busy signal
