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.
