Assured Services for SIP Lines
MLPP Device Setup
The following MLPP configuration fields are located on the device page:
• MLPP Domain
• MLPP Indication
• MLLP Preemption
The MLPP Preemption value is only configurable for Cisco AS-SIP devices. For third party AS-SIP devices,
the determination about whether a call can be preempted is left to the device.
MLPP Precedence Domain Setup
MLPP domain is configured at the device level.
The range of values is 000000 – FFFFFF.
This value is used during preemption decisions. Only calls within the same precedence domain can be
preempted.
MLPP Indication Setup
MLPP can be enabled for the device at 3 different levels – device, common configuration and the enterprise
parameter level.
Set the MLPP Indication to On to enable MLPP regardless of the enterprise or common config settings.
Set the MLPP Indication to Default to cause MLPP to be enabled for the device if it is enabled at the common
device config or enterprise parameter levels.
When MLPP Indication is set to Off, MLPP is disabled for the device regardless of the common device or
enterprise parameter configuration.
MLPP Preemption Setup
MLPP preemption determines whether preemption for reuse can be performed on the device. This type of
preemption is used to remove an existing call and offer a higher precedence call to the user of the device.
When set to Disabled, only preemption 'not for reuse' can be performed on the device. This type of preemption
occurs when the user of the device is not the called party but is either in a call with the called party or is using
a network resource that is preempted; for example, a trunk channel or reserved bandwidth allocation.
When set to Forceful, preempt for reuse is enabled and existing calls may be preempted to offer a higher
precedence call to the user of the device.
When set to Default, the setting from the common configuration or enterprise level is used.
MLPP Authorization Setup for SIP Profile
Enable MLPP Authorization for a device by checking the MLPP User Authorization check box in the phone
section of the SIP Profile used for the device.
