To add a user, you will have to log in with your administrator username and password, then go to Users. This section will allow you to add or manage the users within the organization. You have to set up the username, password, security permissions and access rights. Reboot the system after applying the settings and the new user can log in with the details you have set up. For any other information, I recommend checking the official website of the product: http://www.genband.com/products/continuum/c15-call-session-controller
