But you are obviously not going to get the real calling number for
anyone using SPRINT, WATS extenders, etc.  A better idea for screening
calls than checking the calling number would be if all phones were touch
tone and you required the caller to give a code.  After all, what about
the case of someone you really do want to be able to all you who just
happens to be calling from a pay phone?

Remember, one reason that no record is kept of called numbers for
billing in many European countries, where the government runs the phone
company, is that the collection of such information can be an invasion
of privacy.  If the calling number were always forwarded to the called
office/instrument, then your local law enforcers could also find out the
numbers of all the peoplle who were calling you.
