What early ‘80s hit inspired thousands of unwanted phone calls?

Remember the days not only before cell phones but before caller ID? It was madness.

If your phone rang and you were home, not only did you definitely answer it, everyone in the house raced to be the first to pick it up. It could literally be anyone calling you for all you know, but you sure as hell weren't going to miss that chance to interact with the outside world.

Now if I get a call I don't recognize, and usually even when I do know who it is, I immediately decline it. Who the crap still wants to actually talk on a phone??

But that's why in the '80s there were simply more songs about calling people. And this one inspired a bunch of unwanted calls — and still does to this day. Which song is it?
