Setting up call diversion in the FRITZ!Box

Call diversion allows you to automatically divert all calls or only selected calls to another line, a specific 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 specify that all calls to a specific telephone number are forwarded to a different line, or that all calls are forwarded to a different line when your line is busy.

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