Chapter 18: Multi-Level Precedence and

Overview

The Multi-Level Precedence and Preemption (MLPP) service functionality allows you to place
calls at varying levels of precedence; that is, you can specify the precedence level of each call
you place.
Higher precedence calls preempt those lower in precedence when a user has no free call
appearances
Warning:
Emergency 911 calls are preempted when there are no available call appearances and there
is an incoming above-Routine precedence call.
You can only initiate a call with a precedence level equal to or below the authorized precedence
level that is configured for you. Any call you make automatically defaults to Routine, unless
you choose a higher precedence. During call processing, this precedence level is used to
assure preferential call completion of higher precedence calls within the same MLPP service
domain, even if that means preempting lower precedence calls. Once you set the precedence
level for a call, the precedence level for that call cannot be changed.
The precedence levels are:
• Routine
• Priority
• Immediate
• Flash
• Flash-Override
