I bought the repeater for a Fitzbox 7220. Even when setting up the drama went off! FritzBox to unencrypted DECT signal switched (important, otherwise not go!). Then the repeater tries to register. With the included instructions not simply because it is not very clear. Coincidentally work to log into the dog felt the first attempt. Then, however, call on the repeater was almost not, either one could speak or hear both walked rarely, just accidentally! Most of the repeater the calls but ended even before you could tell which direction because this time went. Conclusion as much chance for that kind of money is not at all -> back to Amazon!
