Question about Gigaset Comfort 500 A Duo (CH-Version)

Hello, would the Comfort 500A be compatible with the DX800A station? I checked here: https://www.gigaset.com/de_de/cms/service/kompatibilitaet/produkte/compatibility.html#product1=282&product2=1015 But the name is not an exact match. We would like to use up to 5 connected mobiles.
