Setting up call blocks for incoming and outgoing calls (e.g. premium-rate numbers)

You can set up call blocks in the FRITZ!Box to

  • block outgoing calls to specific telephone numbers or number ranges (for example premium-rate numbers). Telephones connected to the FRITZ!Box are then no longer able to call these numbers.
  • block incoming calls from specific telephone numbers or number ranges. You can also block callers who do not transmit their telephone number (anonymous callers). Then the telephones connected to the FRITZ!Box do not react to incoming calls from these callers and the calls are not recorded in the call list of the telephones. However, the calls are displayed as rejected calls in the FRITZ!Box call list.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

1 Blocking outgoing calls and defining exceptions

Blocking a telephone number or range of telephone numbers

  1. Click "Telephony" in the FRITZ!Box user interface.
  2. Click "Call Handling" in the "Telephony" menu.
  3. Click the "New Blocking Rule" button.
  4. Enable the option "outgoing calls".
  5. If you want to block a specific number, enter the number in the "Telephone number" field.
    • If you want to block a specific number range, enter this number range in the "Telephone number" field (for example 123) or select a preconfigured range.
  6. Enter a name for the call block. The name is then displayed in the call list of the FRITZ!Box.
  7. Click "OK" to save the settings.

Configuring exceptions for blocked number ranges

If you blocked outgoing calls to a specific number range, you can use a dialing rule to configure exceptions for individual numbers or number ranges. Then you can call these numbers or number ranges despite the block:

  1. Click "Telephony" in the FRITZ!Box user interface.
  2. Click "Call Handling" in the "Telephony" menu.
  3. Click on the "Dialing Rules" tab.
  4. Click the "New Dialing Rule" button.
  5. Select the option "Telephone number" from the drop-down list "Number range".
  6. Enter the complete telephone number including area code or enter a number range you want to allow calls to.

    Example:
    You configured a block for international calls but still want to allow calls to be made to the USA. Enter the country code for USA, "001", as the telephone number when configuring the dialing rule.
    You configured a block for the mobile telephone network but want to allow calls to your mobile telephone number. In this case, enter your complete telephone number when configuring the dialing rule.

  7. For "Connect via", select the telephone number to be used to call the number.
  8. Click "OK" to save the settings.
