Never again nuisance calls

Sales calls, alleged lottery wins and annoying surveys – many unwanted landline calls cost not only time, but also nerves. With a FRITZ!Box you can block telephone numbers from which you do not want to receive calls.

Easy call blocking

You can configure up to 32 call blocks in your FRITZ!Box. If more than 32 telephone numbers are to be blocked, you can also block entire ranges of numbers. Or create a separate telephone book for all of the undesired callers and have the FRITZ!Box automatically block them all.

Anonymous calls can also be blocked. When no telephone number is transmitted the call can be either blocked or automatically routed to an internal answering machine.

Watch out for service numbers

What's more: With a FRITZ!Box you can also block outgoing calls to save money. Many telephone numbers with the prefix "0900", for instance rack up ridiculous charges. To spare your telephone bill from such surprises, and to make sure that such numbers aren't dialed by accident, block these telephone numbers. If in rare cases you do need to place a call to a blocked range of numbers, you can set up a rule to this effect.

Read here how to block incoming calls from and outgoing calls to undesired telephone numbers.
