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.

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.

 

 

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.
