Chapter 3 Setting Up the Cisco Unified IP Phone Configuring Security on the Cisco Unified IP Phone 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 be 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.
