Setting up call diversion in the FRITZ!Box

Call diversion allows you to automatically divert all or selected calls to another line, a particular telephone, or an answering machine. Calls are either diverted by the FRITZ!Box, or they are forwarded through your telephony provider's exchange.

For example, you can define that all calls to a particular number are forwarded to a different line, or you can have all calls forwarded to a different line if your line is busy.

Requirements / Restrictions

  • Calls to a mobile telephone number configured in the FRITZ!Box cannot be diverted.
  • For security reasons, you cannot set up call diversions to premium-rate numbers.
  • With some types of call diversion, calls from "important persons" from your telephone book are forwarded as a parallel call. For example, if all calls are diverted immediately, then telephones still ring when these callers call.
  • Internal calls cannot be diverted.

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

  2. Click "Call Handling" in the "Telephony" menu.

    All calls from callers who do not transmit their caller ID (anonymous calls)
    • Enable "All calls without a telephone number to".
  6. Define where the calls should be diverted to:

    Important:Configure the answering machine accordingly if you want to divert anonymous calls to one of the FRITZ!Box's internal answering machines.

    Divert to where?Setting
    To one of the the FRITZ!Box's internal answering machines
    • Enable the option "Divert calls to internal answering machine" and select an answering machine.
    To an external telephone number (for example a different line, a mobile telephone)
    • Enable the option "Destination telephone number" and enter the destination telephone number.
    To a connected telephone or an answering machine
    • Enable the option "Destination telephone number" and enter the internal number of the device without asterisks. You can find the internal numbers under "Telephone Book > Internal Numbers". It is not possible to divert calls to more than one device.
  7. If you select the option "Automatically" from the drop-down list "Outgoing caller ID", the FRITZ!Box tries to set up call forwarding in the telephone exchange of your telephony provider. The requirements given below must be met to set it up at the provider. If it cannot be set up at the provider, then call diversion is performed in the FRITZ!Box:

    Important:If you set up call blocks for incoming calls in the FRITZ!Box, they no longer apply if call diversion is set up at the provider.

    1. No dialing rules or call blocks are configured in the FRITZ!Box for the destination telephone number.
    2. Your provider supports the setup of call forwarding. With some providers, you can also set up call diversions in your personal customer area in the internet.
    3. The option "Calls to a telephone number / telephone" is enabled and a telephone number is selected.
    4. "Immediately", "delayed" or "when busy" is selected as the "Type of call diversion".

      Note:In the FRITZ!Box you cannot see whether the call diversion was set up at your provider's or in the FRITZ!Box.

  8. If you can choose between different settings in the drop-down list "Type of call diversion", for example immediately, when busy, or parallel call, select one. Some call diversions do not allow you to select a type.

    Note:You can find further information on the different settings in the FRITZ!Box's online help, which you can access by clicking the "Help" symbol .

  9. Click "OK" to save the settings and confirm that the procedure may be executed on the FRITZ!Box, if asked to do so.

2 Enabling the schedule

You can use the schedule to automatically enable or disable call diversions, or you can do so directly in the user interface, or using the MyFRITZ!App:

  1. Click "Telephony" in the FRITZ!Box user interface.
  2. Click "Call Handling" in the "Telephony" menu.
  3. Click on the "Call Diversion" tab.
  4. Enable the option "Switching Call Diversion On and Off by Schedule".
  5. In the weekly overview, mark the times when call diversion should be enabled in blue.

    Note:You can mark the same periods of time for several days by holding down the left mouse button while dragging the mouse across the weekly overview.

  6. In the list of all call diversions, enable the ones that should be subject to the schedule.
  7. Click "Apply" to save the settings.

The schedule is now configured; your settings will take effect once the next switching time has been reached.

Important:If the incorrect status (enabled or not enabled) is displayed for the call diversion now, manually enable or disable it once. The schedule will not be deactivated if you switch it off manually. Instead, it automatically takes effect when the next switching time has been reached.
