FRITZ!Box 3272 – Service

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

You can create call blocking rules in the FRITZ!Box in order to

  • block outgoing calls to certain 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 certain telephone numbers or number ranges. In addition, 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 saved in the call list of the telephones. However, they are displayed as rejected calls in the FRITZ!Box call list.

Important:Some of the settings described here are only displayed if the advanced view is enabled in the user interface. The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS

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. Either enter a complete number or a number range.

    Note:A range of telephone numbers contains all telephone numbers that begin with the specified numerals. For instance, the range "00" contains all telephone numbers that start with "00". This means all international calls.

  6. Click "OK" to save the settings.

Configuring exceptions for blocked ranges

If you blocked outgoing calls to a particular number range, then you can configure a dialing rule that will allow exceptions for individual numbers or number ranges. You can still call these numbers or 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 number including area code or enter a number range you would like to be able to make calls to.

    Example:
    You configured a block for international calls but still would like to make calls to the USA. In this case, 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 would like 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 dial the number.
  8. Click "OK" to save the settings.

2 Blocking incoming calls

Anonymous calls

  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 "incoming calls".
  5. Select "Without a number" from the drop-down list "Number range".
  6. Click "OK" to save the settings.

Calls from a certain telephone number or number range

You can create a maximum of 32 call blocks. If you would like to block more than 32 numbers, either block number ranges or save these numbers in their own telephone book and block this telephone book. All calls from contacts saved in this telephone book are then blocked:

  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 "incoming calls".
  5. If you would like to block a certain number or number range, enter the number or desired range (for example 123) in the "Telephone number" field.
    • or, if you would like to block a telephone book:
      1. Select "Telephone book" from the drop-down list "Number range".
      2. From the drop-down list, select the telephone book that contains the numbers and number ranges you would like to block. Ranges must end with a *.

        Example:
        If you want to use the telephone book to block the range "123", create a telephone book entry for the number 123*.

  6. Click "OK" to save the settings.
