Place a Priority (Precedence) Call
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.
Priority level of an MLPP call
To see the priority level of an MLPP 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).
Note Contact your system administrator for a list of corresponding precedence numbers for calls.
To Make a Priority (Precedence) Call:
Enter the MLPP access number (provided by your system administrator) followed by the Precedence level (0-4) and the phone number.
Note If you enter an invalid MLPP access number, a verbal announcement alerts you of the error.
To Answer an MLPP Call:
End an active call (if necessary) and answer the MLPP call.
If the active call has lower precedence than the incoming call, the active call is preempted.
Tips
–When you are receiving a priority (precedence) call, an MLPP icon on your phone screen indicates the priority level of the call.
–When you make or receive an MLPP-enabled call, you hear special ring tones and call-waiting tones that differ from the standard tones.
–When you or the other party are receiving a call that must preempt the current call, disconnect immediately to allow the higher priority call to ring through.
–When you have more than 1 active call, the call with the lowest precedence will be preempted. Similarly, for outgoing calls, the call with lower precedence will be preempted first.
