This must be a line use by overseas phone companies. I just got a call from a number I didn't recognize, so I hung up, then I got a call from the number above less than 10 seconds later. The first number ended up being from Ethiopia. I think the second ring was a fluke from the phone carrier.
Anyway.

I started getting these calls, too.  First a call from a unknown area code then this call a few minutes later.
If I register my cell # on Do Not Call, will that stop these calls?
