The Gigaset DESK 800A is a DECT base station with an analogue telephone connection and integrated answering machine. It is a wired telephone that is connected to an analogue telephone socket.

If there are telephone sockets on different floors that are supplied by the Sunrise router, the DESK 800A can be operated at any of these analogue telephone sockets, even if the router is not located directly on the same floor. The prerequisite is that the telephone line on this floor is active and connected to the analogue connection of the Sunrise router.

The telephone itself does not require a direct connection to the router, only an analogue telephone line. It is not a DECT handset that connects wirelessly to a base station, but a wired telephone that is connected to the telephone socket.

To summarise: The Gigaset DESK 800A works with any analogue telephone socket that is supplied by the Sunrise router, even if the router is not on the same floor.
