Prioritizing Critical Calls
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
.
Tips
•
When you make or receive an MLPP-enabled call, you will hear special ring tones and call-waiting
tones that differ from the standard tones.
•
If you enter an invalid MLPP access number, a verbal announcement will alert you of the error.

Hear a special ring (faster than
