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.
Want to choose a priority (precedence) level for an outgoing call
Contact your system administrator for a list of corresponding precedence numbers for calls.
Want to make a priority (precedence) call
Enter the MLPP access number (provided by your system administrator) followed by the phone number.
Hear a special ring (faster than usual) or special call waiting tone
You are receiving a priority (precedence) call. An MLPP icon 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).
Want to accept a higher-priority call
Answer the call as usual. If necessary, end an active call first.
Hear a continuous tone interrupting your call
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.
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.
Transferring Calls
Transfer or redirects a connected call. The target is the number to which you want to transfer the call.
Transfer a call without talking to the transfer recipient
1. From an active call, choose Options >Trnsfer.
2. Dial the target number.
