Zapper
Several years ago I had a call zapper that I got at Radio Shack for about $10.00. As I recall, it detected computer generated calls and sent back a signal telling the computer this was not a "live" line. We never even knew there was an incoming call. We stopped using it after a while when the computers stopped calling, because it also blocked incoming FAX. Now that nobody uses FAX anymore, maybe I'll look for a replacement.
Any current experience out there?
