Very odd phone calls: shortwave number-station style

There’s an old column about something like this. It’s from 1988 so I’m not sure how relevant it is. What causes “ghost rings” on the telephone?

But if the phones the OP has are really old Western Electric models with an actual bell, it would a pretty big voltage spike to make it ring.

Good point.
