/mcpDescription MLPP Settings for Phones Field Be aware that this setting is not available on all devices. If available, this setting specifies whether a device that can preempt calls in progress will use the capability when it places an MLPP precedence call. From the drop-down list, choose a setting to assign to this device from the following options: • Default —This device inherits its MLPP preemption setting from the common device configuration. • Disabled—This device does not allow preemption of lower precedence calls to take place when necessary for completion of higher precedence calls. • Forceful—This device allows preemption of lower precedence calls to take place when necessary for completion of higher precedence calls. MLPP Preemption ConfigureaDirectoryNumbertoPlaceMultilevelPrecedenceandPreemption Calls After you configure a device, you can add a line (directory number) from the updated Device Configuration window. Procedure Step 1 From Cisco Unified CM Administration in the Device Configuration window, click Add a new DN for the appropriate line. Step 2 In the Target (Destination) field, enter the number to which MLPP precedence calls should be diverted if this directory number receives a precedence call and neither this number nor its call forward destination answers the precedence call. Values can include numeric characters, octothorpe (#), and asterisk (*). Step 3 From the MLPP Calling Search Space drop-down list, choose the calling search space to associate with the MLPP alternate party target (destination) number. Step 4 In the MLPP No Answer Ring Duration (seconds), enter the number of seconds (between 4 and 60) after which an MLPP precedence call is directed to this directory number alternate party if this directory number and its call-forwarding destination have not answered the precedence call. Leave this setting blank to use the value that is set in the Precedence Alternate Party Timeout enterprise parameter. Step 5 Click Save.
