Transmitting own telephone number

When you make calls, you can automatically transmit your telephone number (caller ID) to the person you are calling. The person you call can then see your telephone number in the display of their telephone.


  • The feature "caller ID blocking (CLIR) for individual calls" must have been enabled by your telephony provider.

1 Disabling caller ID blocking (CLIR)

  1. Start FRITZ!App Fon.
  2. Tap "More" and then "Settings".
  3. Disable the option "Tel. No. Suppressed".

If the telephone number is not automatically transmitted when you make calls now, you must have your telephony provider enable the feature "caller ID blocking (CLIR) for individual calls". No further settings in the FRITZ!Box are necessary.
