First of all a 121 Area Code is not legit. Let the answering machine pick it up and of course no message. Besides blocking numbers which really does no good because all or most of them have hundreds of numbers they call from. One of the best things I do ( if I am home) as soon as I see unknown #'s is to switch my fax machine on. This slows them down for a while. I think the federal government needs to step in and put it on the telephone companies for sellin phones to these illegal people.
