With Unity
Connection 11.5(1) SU3 and later, you cannot enable the encryption on Unity
Connection in Demo mode. It means you are not allowed to use the security
modules in Unity Connection. To enable the encryption in Unity Connection, you
must communicate with PLM and an encryption license $0 ENC SKU must be
installed on the PLM.
For information on how to purchase the encryption licenses, see
https://www.cisco.com/c/en/us/products/collateral/unified-communications/unity-connection/guide-c07-734922.html.
After connecting
Unity Connection to the PLM server, run "utils cuc encryption enable" CLI
command to enable the encryption on Unity Connection.
For more information
on the CLI command, see the Command Line Interface Reference Guide for Cisco
Unified Solutions for the latest release, available at

In Violation or
Expire mode, Unity Connection generates an alarm to disable the encryption on
