Who I have the same questioned this topic

FYI, we have been hit by the One Ring scam the past few days. Call comes from strange number to cell phone at odd hour. Rings once and no more. If you call back out of curiousity, there is a hefty change. Don't know how much yet.  Calls have come from different numbers in Belarus and Slovenia. Do not call back! Lots of info about this on the web but haven't seen any on Verizon web site.
