May be you want to manage CME using a Graphical User Interface. Cisco has released multiple GUI management tools to configure CME over the years. CCP (Cisco Configuration Professional) is the management tool not just for CME but also for managing other features. Through CCP you can configure all major aspects of the CME router. After installing CCP on your pc and configure all requirements on the CME router (define username and password on privilege 15, enable http server, enable login local in vty 0 4) but CCP error appears as “invalid username or password”. You can find this entire configuration in “CCNA Voice Cisco press” book. Now it seems that on command was omitted or have forgotten in the book. Here is the important command that solve the problem:

RouterCME(config)#ip http authentication local

This command was introduced on IOS 11.2F, and specifies the authentication method to be used for login when a CCP connects to the HTTP server.
