Because Stern is in radio, him or his crew must have the private numbers and names that enable these people to get through.

Once upon a time, I played around with a voice PRI line (Primary Rate Interface, the ISDN equivalent of a voice T1 line), connected to an Adtran Atlas 800, which in turn was connected to a phone system, a LAN, and some videoconfencing gear. IIRC, you could configure the Adtran box to present caller ID info that you configured to the telco switch. I wonder if Stern doesn't have some techies around using this function.
