All you'd have to do is send a short signal to block/jam the legit one sent by the phone company, and then send yours afterwards, if the the whole transaction only takes a few tenths of a second, you'd still have time to spoof a signal between rings. You could change the date and time or your number. Somehow I love the idea of people calling me back and reaching the White House :>. Since your phone can transmit to the other line before the phone is picked up, it should be quite easy to implement this. Just have your machine send the jam & spoof every time you dial. just press a key before you dial the last number in the number you're trying to reach. Then once the jammer hears that you've dialed a number on the phone keypad, it would jam for enough time to cancel the legit signal, and then transmit the number/combo of your choice. Anyone in a caller id zone wanna try it? >Ghost Wheel Louis Ruppert lruppert@mailbox.syr.edu
