There are interactions, restrictions, and limitations that affect how security features work on 
your phone. For more information, contact your system administrator.

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.

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. 

Notify your system 
administrator about a 
suspicious or harassing call

Choose Options > MCID. 

Your phone plays a tone and displays the message, “MCID successful.”
