Available Features Enabled by Administrators

There are features on your IP Phone that you can use ONLY if an Administrator has enabled them on your phone. Those features are described in this section. Contact your System Administrator for more information.

Outgoing Intercom Calls

If your System Administrator configures the outgoing intercom feature on your phone, pressing the Icom button allows your phone to find an available line and place an intercom call to a recipient. To use this feature, you must configure an intercom key on your phone. For more information about configuring and using an Icom key, see "Intercom Key" on page 104.

Missed Call Summary Subscription

A feature on the IP phones allows missed calls that have been redirected by the server, to be incremented in the missed calls indicator on the phone it was initially directed to. This feature is called the Missed Call Summary Subscription and can be configured by your System Administrator. For this feature to work, you must configure voicemail on the phone that the call was initially directed to.

For example, phones A, B, and C are connected to the server. Your Administrator configures the server to direct calls coming into phone B (which has voicemail configured) to be forwarded to phone C. When phone A calls phone B, the server forwards the call to phone C. With the Missed Call Summary Subscription enabled, phone B receives notification from the server that the call was forwarded and the missed calls indicator is incremented on phone B. See the illustration below.
