If you are not using DHCP in your network, you must configure these network settings on the
Cisco Unified IP Phone after installing the phone on the network:
•
IP address
•
IP subnet information (subnet mask for IPv4 and subnet prefix length for IPv6)
•
Default gateway IP address
•
TFTP server IP address
•
You also may configure the domain name and the DNS server settings, if necessary.
Cisco Unified IP Phone Settings, on page 59.
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.

Make sure that the appropriate Cisco Unified Communications Manager and the Certificate Authority Proxy
Function (CAPF) security configurations are complete:
•
The CTL file or ITL file should have a CAPF certificate.
•
On Cisco Unified Communications Operating System Administration, verify that the CAPF certificate
has been installed.
•
The CAPF is running and configured.
