Registering FRITZ!Fon

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 one. 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 and wireless data transmission. All FRITZ!Box models support this standard.
