You can also cause certain numbers to be automatically screened out. If someone has an unlisted number, it won't show, but for $3 you can call a phone company number immediately and get an in- stant trace. This setup has obvious implications for computers on modems. Once widely implemented, it will virtually eliminate phone line hack- ing. Sean Casey "Engineers...they just LOVE to change things."
