Aastra Telecom 6735I User Manual

41-001451-00 REV00 – 07.2011

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.

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.

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.

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.

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.

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.

Your Administrator can set a time period delay before the phone automatically answers. Contact your System Admin-
istrator for more information.
