Yes, you can block undesired calls by implementing an undesired calls filter. You can fill in the number(s) of the persons or parties from which you don’t want to receive any more calls and adjust your undesired calls filter every day.

Does it work?

Yes, usually our undesired calls filter works perfectly. Nevertheless, sometimes persons or parties possess different numbers or change their number regularly. In this case, it would be necessary to continually change the calls that need to be filtered which is rather difficult of course.

However, we can give you advice about what to do if a person does not stop calling you against your will and are confident that together we will find a solution to your problem.
