Kentucky State Police are warning of a rash of "one-ring" phone scams reported by the Better Business Bureau.
An automated system will call your phone and hang up after one or two rings.
If you return the call, you will incur a fee of around $20 dollars with additional fees charged for every minute you are on the phone.
The Better Business Bureau says most of the calls originate from area codes in the Caribbean Islands.
If you receive a call from the following area codes, and do not know the caller personally, do not return the call.
Dominican Republic - 809
Jamaica - 876
British Virgin Islands - 284
Grenada - 473
Aruba - 297
Antigua - 268
