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
