IP Phone Administrator Guide Operational Features

Operational IP Phone Features

Allow Barge In

You can configure whether or not the IP phone allows an incoming intercom call to interrupt an active call. The “sip intercom allow barge in” parameter controls this feature. When you enable the sip intercom allow barge in parameter

(1 = enable in the configuration files), 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 (0 = disable in the configuration files), and there is an active call, the phone treats an incoming intercom call like a normal call and plays the call warning tone. You can set this parameter using the configuration files or the Aastra Web UI.

For incoming intercom calls, an administrator or user can configure the following parameters:

Configuration File Parameters		Web UI Parameters
• sip allow auto answer		•	Auto-Answer
• sip intercom mute mic		•	Microphone Mute
•	sip play warning tone	•	Play Warning Tone
•	sip intercom allow barge in	•	Barge In

Note: To configure incoming intercom calls using these parameters, see “Configuring Intercom Calls Settings” on page 5-62.

Configuring Intercom Calls Settings

You can configure the Intercom feature using the configuration files or the Aastra Web UI.

Note: An administrator can configure the incoming and outgoing Intercom feature. A user can configure the incoming Intercom feature only.
