Registering FRITZ!Fon

You want to register a cordless telephone with the FRITZ!Box? ✔ Here we show you how to easily connect your DECT telephone.

Our FRITZ!Fon models are perfectly coordinated with the FRITZ!Box. Simply use the wizard in the FRITZ!Box user interface or your telephone's menu to register them. You can register a FRITZ!Fon with up to four base stations. To switch the active base station, select "Menu > Settings > Registration > Select Base". Of course you can also use the menu to register FRITZ!Fon with a base station from another manufacturer.

Requirements / Restrictions

  • The base station must support the DECT-GAP profile. 

    Note:DECT-GAP is a common standard for cordless telephones supported by all FRITZ!Box models with integrated DECT base stations.
