Prioritizing Critical Calls

(SCCP phones only)

In some specialized environments, such as military or government offices, you might need to make and receive urgent or critical calls. If you have the need for this specialized call handling, your system administrator can add Multilevel Precedence and Preemption (MLPP) to your phone.

Keep these terms in mind:

•Precedence indicates the priority associated with a call.

•Preemption is the process of ending an existing, lower priority call while accepting a higher priority call that is sent to your phone.

If you...	Then...
Want to choose a priority	Contact your system administrator for a list of
(precedence) level for an outgoing call	corresponding precedence numbers for calls.
Want to make a priority (precedence)	Enter the MLPP access number (provided by your system
call	administrator) followed by the phone number.
Hear a special ring (faster than usual)	You are receiving a priority (precedence) call. An MLPP icon
or special call waiting tone	on your phone screen indicates the priority level of the call.
Want to view priority level of a call	Look for an MLPP icon on your phone screen:
	Priority call
	Medium priority (immediate) call
	High priority (flash) call
	Highest priority (flash override) or Executive
	Override call
	Higher priority calls are displayed at the top of your call list.
	If you do not see an MLPP icon, the priority level of the call
	is normal (routine).
Hear a continuous tone interrupting	You or the other party are receiving a call that must preempt
your call	the current call. Hang up immediately to allow the higher
	priority call to ring through.

Tips

•If you enter an invalid MLPP access number, a verbal announcement will alert you of the error.

•An MLPP-enabled call retains its priority and preemptive status when you:
