Cisco Unified IP Phone Security

The 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 Cisco Unified Communications Manager Security Guide.

Install Locally Significant Certificate
You can initiate the installation of a Locally Significant Certificate (LSC) from the Security Configuration
menu on the phone. This menu also lets you update or remove an LSC.

SHA-1 as the algorithm to sign certificates. The phones do not support SHA-2 (SHA256). For more information
on the use of a Third Party CA to sign LSCs, see CUCM Third-Party CA-Signed LSCs Generation and Import
