Note There are interactions, restrictions, and limitations that affect how security features work on
your phone. For more information, contact your system administrator.
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
.
Verify that the phone on the other
end of the connection is also secure Look for the encrypted lock icon and listen for a security tone
at the beginning of a call.
When encrypted calling is configured on your phone, the lock
icon displays. However, the conversation is protected only
when the security tone plays at the beginning of a call,
indicating that the call is protected on both ends of the call. If
your call is connected to a non-protected phone, the secure
tone does not play.
Determine if secure calls can be
made in your company Contact your system administrator.
