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. Call diversion takes place in the FRITZ!Box or the telephone exchange of your telephony provider.

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

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