Can I continue to use my FRITZ!Fon with the Sunrise Internet Box?
The Sunrise Internet Box supports DECT CAT IQ 2.0 functions only on phones that meet this standard.
Therefore, the FRITZ!Fon does not work the way the FRITZ!Box does when it is connected to a Sunrise Internet Box.
For example, you cannot connect to the Internet box phone book. The basic functions, however, work.
