Configuring call forwarding through the exchange
With call forwarding through the exchange, you can automatically divert incoming calls to a different line, for example to your mobile telephone. Calls are forwarded by the telephone exchange of your telephony provider and not in the FRITZ!Box.
You can either use the FRITZ!Box user interface to configure call forwarding, or you can use the menu of an ISDN telephone.
Requirements / Restrictions
- The telephony provider supports configuration of call forwarding.
Note:With some telephony providers, you can also configure call forwarding in your personal customer area in the Internet.
- No dialing rule or call blocks have been configured in the FRITZ!Box for the destination number.
Note:The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS for your FRITZ!Box.
