/mcpMultilevel Precedence and Preemption Settings for Phones Table 87: Multilevel Precedence and Preemption Settings for Phones Description MLPP Settings for Phones Field Choose the common device configuration that you configured. The common device configuration includes the attributes (services or features) that are associated with a particular user. Common Device Configuration From the drop-down list, choose a calling search space (CSS) that you configured . A calling search space comprises a collection of partitions that are searched to determine how a dialed number should be routed. The calling search space for the device and the calling search space for the directory number are used together. The directory number CSS takes precedence over the device CSS. Calling Search Space Choose an MLPP domain from the drop-down list for the MLPP domain that is associated with this device. If you leave the None value, this device inherits its MLPP domain from the value that was set in the common device configuration. If the common device configuration does not have an MLPP domain setting, this device inherits its MLPP domain from the value that was set for the MLPP Domain Identifier enterprise parameter. MLPP Domain If available, this setting specifies whether a device that can play precedence tones 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 indication setting from the common device configuration. • Off—This device does not handle nor process indication of an MLPP precedence call. • On—This device handles and processes indication of an MLPP precedence call. Note Do not configure a device with the following combination of settings: MLPP Indication is set to Off or Default (when default is Off) while MLPP Preemption is set to Forceful. Turning on MLPP Indication (at the enterprise parameter or device level) disables normal Ring Setting behavior for the lines on a device, unless MLPP Indication is turned off (overridden) for the device.
