IPMA, EM and CallManager Attendant Console.
A user can access a service from the supported phone model in two ways. The user can press the button labeled "services," or user can use a preconfigured phone button. When the user presses the services button, the phone uses its HTTP client to load a specific URL that contains a menu of services to which the user has subscribed for the phone. The user then chooses a service from the listing. When a service is chosen from the menu, the URL gets requested via HTTP, and a server provides the content, which then updates the phone display. When the user presses the phone button that is configured for a service, the URL gets requested via HTTP.
