Maximum number of incoming call blocks and call diversions

In the FRITZ!Box, you can set up call blocks for incoming calls to block calls from unwanted callers. You can also divert calls to a specific destination depending on the caller's telephone number. However, the number of calling rules based on a caller's number (caller ID) you can set up is limited to 32. These calling rules include:

  • Call blocks for incoming calls
  • Call diversion for "Calls by a person in the telephone book"
  • Call diversion for "Calls from the telephone number"

You already configured 12 call blocks for incoming calls and 10 call diversions for persons in the telephone book. This means you can still set up 10 call diversions for calls from specific telephone numbers.

Note:To reduce the number of call blocks, you can also block number ranges in the FRITZ!Box. This way you can block incoming calls from all callers whose number begins with 0900, for example.
