Chapter 40 Cisco IP Phones

Phone Features

Call forward all—Forwards all calls.

Call forward busy—Forwards calls only when the line is in use and busy trigger setting is reached.

Call forward no answer—Forwards calls when the phone is not answered after the configured no answer ring duration.

The administrator can configure call forward information display options to the original dialed number or the redirected dialed number, or both. The administrator can enable or disable the calling line ID (CLID) and calling name ID (CNID). The display option gets configured for each line appearance.

The call forward busy trigger gets configured for each line appearance in a cluster and cannot exceed the maximum number of calls that are configured for a line appearance. The call forward busy trigger determines how many active calls there are on a line before the call forward busy setting gets activated (for example, 10 calls).

The call forward no answer ring duration gets configured for each line appearance in a cluster, and the default specifies 12 seconds. The call forward no answer ring duration determines how long a phone rings before the call forward no answer setting gets activated.

Tip Keep the busy trigger slightly lower than the maximum number of calls, so that users have the ability to make outgoing calls and perform transfers.

Configure call forward in the Directory Number Configuration window in

Cisco CallManager Administration.

Call Park

Call park allows a user to place a call on hold, so anyone who is configured to use call park on the Cisco CallManager system can retrieve it.

For example, if a user is on an active call at extension 1000, the user can park the call to a call park extension such as 1234, and another use can dial 1234 to retrieve the call.

To use call park, you must add the call park extension (in this case, 1234) in Cisco CallManager Administration when you are configuring phone features. For more information about call park, refer to Call Park in the Cisco CallManager Features and Services Guide.
