To control which telephones can make intercom calls to each other, you add the telephones in groups called intercom groups. Once you add a set of telephones to the group, users can make intercom calls by administering one or both of the following feature buttons on their telephones:
Automatic Intercom
Users use this button to call one predefined telephone in the same intercom group. You specify the destination extension for this button.
Dial Intercom
Users in an intercom group use this button to call anyone else in the same group. The user lifts the handset, presses the Dial Intercom button, and then dials a 1 digit or a 2 digit code for the extension.
Telephones with both of these capabilities can belong to the same intercom group.
