Security features protect against several threats, including threats to the identity of the phone and to data. These features
establish and maintain authenticated communication streams between the phone and the Cisco Unified Communications Manager
server, and digitally sign files before they are delivered.
For more information about the security features, see the Security Guide for Cisco Unified Communications Manager.
You can start the installation of a Locally Significant Certificate (LSC) on the device profile from Cisco Unified Communications
Manager. Use the menu option. You can also use this menu option to update or remove an LSC.
Before you begin, make sure that the appropriate Cisco Unified Communications Manager and the CAPF security configurations
are complete:
-
On Cisco Unified Communications Operating System Administration, verify that the CAPF certificate has been installed.
-
The CAPF is running and configured.
See the Security Guide for Cisco Unified Communications Manager for more information.
