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.

Note:The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS for your FRITZ!Box.
