Free call-blocking program

FritzBlock is an all-in-one utility program that enables you to automatically identify incoming calls from your FRITZ!Box. With less than 10 megabytes of RAM, it can identify cold callers and robocalls. It can also keep a log of numbers from people you do not want to receive calls from. The software is based in Germany, but it is accessible for users all over the world. With FritzBlock, you will no longer receive unwanted and bothersome advertising calls. 

How to stop unwanted incoming calls

FritzBlock is your call monitor, phone book editor, and dialing aid in one. Its smart system takes note of your preferences without collecting any of your personal data. It has flexible installation options so you can download the program to multiple devices. You can also install this in your computers with older operating systems. This means you will continue to receive lifetime support from this software's developers.

After reading the calls, the software automatically evaluates the phone numbers via one or more websites that you can set, like tellows. A score is provided for each number. Calls from people that have a bad score will be automatically blocked. You will then receive a report regarding the call so you can block the person permanently. You can also manually block them even if they have a high rating. 

It is not necessary to wait for the pop-up to appear before blocking someone. For incoming calls, the number and name of the caller can be displayed on a remote PC as a toast. Two options will appear on your screen: stop the call and add it to the blacklist or proceed with the call and give it a high rating. FRITZ!Box users can import their contact book to this program to prevent known contacts from receiving a low score. 

Easy way to stop robocalls

FritzBlock is an incredible utility program for blocking telephone numbers by means of the FRITZ!Box. Without the prerequisite program, you will not be able to use this call blocker. It’s well worth it, as spam calls are immediately hushed. The free software has a runtime limit but can be easily reinstalled.
