Creates a button that alerts when a call to the specified covered user is unanswered after that users Individual Coverage Timer expires. For details, see Call Coverage Buttons.
The call coverage appearance button user must also have at least one call appearance button programmed. The covered user does not need to be using call appearance buttons.
Coverage appearance functions, assigned to buttons that do not have status lamps or icons, are automatically disabled until the user logs in at a phone with suitable buttons.
Appearance buttons can be set with a ring delay if required or to not ring. This does not affect the visual alerting displayed next to the button. The delay uses the user's Ring Delay () setting.
