Tracing Suspicious Calls
If you are receiving suspicious or malicious calls, your system administrator can add the Malicious Call
Identification (MCID) feature to your phone. This feature enables you to identify an active call as
suspicious, which initiates a series of automated tracking and notification messages.
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.

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).
