Hi everone I get all kinds of calls not only from this number listed but other numbers all day long. I did some investagating and all you have to do is go to the local walmart or other retail store and pick your self up a panasonic corless phone. It will say right on the box it will BLOCK CALLS and it does. Also when the caller ID comes up unavailble out of area it will block them also it is the only phone that I know of that will do all this. It all works for me good luck
