Which menu should be used to create a username and password in the Cisco Unified CME GUI?

Configure > Pilot Number is used to set up hunt group pilot numbers for call routing, not for creating user credentials.

Configure > Extension manages dial plan extension assignments and is not used for username and password creation.

The Configure > Phones section in Cisco Unified CME GUI allows administrators to define phone entries that include associated user credentials such as username and password. CME ties phone user authentication directly to the phone configuration object rather than maintaining a separate user store. This is where ephone user login credentials are set for phone access and extension mobility.

Configure > System Parameters controls global system-wide settings such as time zones and max phones, not individual user credentials.
