Do you have an Aspire system with a DSS console? If the DSS is set to Hotel/Motel mode, you would get this message for any extensions that are not physically connected to the system.

If you are using this in a hotel, you can cancel the messages. If this is in a business setting, you need to change the operating mode of the DSS console to Business mode.
