Regarding: Tracer Box No, that type of device can NOT be built by normal users of the phone system. It requires work at the local TelCo itself. I heard that one of the Companies (one of Ma Bells pieces) is offering that service on their lines, but with a fee for each call traced. Also, they are offering a box that will display the # of who is calling you as the phone is ringing. (Again at a "small" charge.) Too bad, it could have been useful! --Arun Baheti NBaheti.es@Xerox
