Multilevel Precedence and Preemption

Multilevel Precedence and Preemption
In some environments, such as military or government offices, you may 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
If you want to choose a priority level for an outgoing call, contact your system administrator for a list of
corresponding precedence numbers for calls.
If you want to make a priority call, enter the MLPP credentials provided by your system administrator, followed
by the phone number.
If you hear a special ring that's faster than usual or special call waiting tone, you are receiving a priority call.
