"Call display" is "caller ID". It shows you the number that is calling your
phone. It used to be quite common for people casing a house for a burglary
to call to see if anyone is home. Call display/caller ID was also a great
way to deter people from making harassing phone calls. Having a number
unlisted decreases the chances of someone casing your house to call to
check if you are home. Once I got the call display I didn't feel the need
to maintain an unlisted number.
