May I suggest a compromise patterned after the post office: The phone company should ALWAYS (where possible) send the area code and exchange with every call. This is comparable to a postmark, and can provide some meaningful information to the receiver of the call. The calling party could then optionally send or block the transmission of the unique four digits identifying the call. This corresponds, more or less, to a full return address. =John=
