(KFYI News) Calling back unknown numbers could cost you a lot of money.

It's a phone scam called the "one-ring game."  The Better Business Bureau says fraudsters are going onto their computers, sending thousands of one-ring calls to random cell numbers and disconnecting.  The idea is to get victims to call back.

While you are trying to find out who it is, you're being charged twenty bucks for an international call, part of the scam.  For each additional minute you wait, it'll cost an additional nine dollars.
