Procedure
Step 1 Obtain the CAPF authentication string that was set when the CAPF was
configured.
Step 2 From the phone, press the Settings > Security Configuration.
Note You can control access to the Settings Menu by using the Settings Access
field in the Cisco Unified CallManager Administration Phone
Configuration Settings page. For more information, see Cisco
Unified CallManager Administration Guide.
Step 3 Press **# to unlock settings on the Security Configuration menu.
Step 4 Scroll to LSC and press the Update softkey.
The phone prompts for an authentication string.
Step 5 Enter the authentication code and press the Submit softkey.
The phone begins to install, update, or remove the LSC, depending on how the
CAPF was configured. During the procedure, a series of messages appears in the
LSC option field in the Security Configuration menu so that you can monitor
progress. When the procedure completes successfully, the phone will display
Installed or Not Installed.
The LSC install, update, or removal process can take a long time to complete. You
can stop the process at any time by pressing the Stop softkey from the Security
Configuration menu. (Settings must be unlocked before you can press this
softkey.)
When the phone successfully completes the installation procedure, it displays
“Success.” If the phone displays, “Failure,” the authorization string may be
incorrect or the phone may not enabled for upgrading. Refer to error messages
generated by the CAPF and take appropriate actions.
You can verify that an LSC is installed on the phone by choosing Settings >
Model Information and ensuring that the LSC setting shows Installed.
