Prioritizing Critical Calls - Cisco 7921G - Unified Wireless IP Phone VoIP Phone Manual

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.
If you...
Want to choose a priority
(precedence) level for an outgoing
call
Want to make a priority
(precedence) call
Hear a special ring (faster than
usual) or special call waiting tone
Want to view priority level of a
call
Want to accept a higher-priority
call
Hear a continuous tone
interrupting your call
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.

Then...
Contact your system administrator for a list of corresponding
precedence numbers for calls.
Enter the MLPP access number (provided by your system
administrator) followed by the phone number.
You are receiving a priority (precedence) call. An MLPP icon on
your phone screen indicates the priority level of the 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).
Answer the call as usual. If necessary, end an active call first.
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.
