Cisco Systems 7931G Manual De Usuario

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.

Multilevel Precedence and Preemption (MLPP) overrides the Do Not Disturb (DND) feature.

If you enter an invalid MLPP access number, a verbal announcement will alert you of the error.

An MLPP-enabled call retains its priority and preemptive status when you:

Put the call on hold

Transfer the call

Add the call to a three-way conference

Answer the call using PickUp 

Cisco Extension Mobility (EM) allows you to configure a Cisco Unified IP Phone as your own 
temporarily. Once you log in to EM, the phone adopts your user profile, including your phone lines, 
features, established services, and web-based settings. Your system administrator must configure EM 
for you.

The Extension Mobility Change PIN feature allows you to change your PIN from your Cisco Unified 
IP Phone.

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).

Hear a continuous tone interrupting 
your call

You or the other party are receiving a call that must preempt 
the current call. Hang up immediately to allow the higher 
priority call to ring through.
