You can set up call park in two different ways:

• The parked call displays on the phone where the user can pick it up.

• The user must dial the displayed number to pick up the call.

You set the field Dedicate one line for Call Park in Cisco Unified Communications Manager to enable or disable the feature. By default, the feature is enabled.

When the field is enabled, the parked call remains on the user's line and they can use the Resume softkey to pick up the call. The user sees the extension number for the parked call on the phone display.

When the field is disabled, the parked call transfers to the call park line. The user's line returns to the idle state and they see the call park extension in a pop-up window. The user dials the extension to pick up the call.
