Available Features Enabled by Administrators
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 139 .
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.
Note:
Your System Administrator can configure the Missed Call Summary
Subscription feature on a global or per-line basis.
