Internet telephone numbers cannot be entered or edited
It is not possible to set up new internet telephone numbers, delete telephone numbers that are entered, or edit the settings of the telephone numbers.
Simply proceed as described below. After each measure, check whether the problem is solved.
1 Maximum number has been reached
A maximum of 20 internet telephone numbers can be entered in the FRITZ!Box. If 20 internet telephone numbers were already configured, you cannot set up any more internet telephone numbers.
2 Only the provider can make changes
With some providers, the telephone numbers are automatically configured in the FRITZ!Box when the internet connection is configured. With these providers, it is not possible to later change the settings for telephone numbers that were configured automatically or enter additional telephone numbers in the FRITZ!Box.
Refer to your internet provider for information on entering and editing telephone numbers.
