Its a call re-origination probably from another country. Scammer, finds things to buy, usually off non-auction websites like craigslist. Basically they call an assigned number to the U.S. and then it gives it a different phone number to finish making the call. You shouldn't get charged for any international number. But be aware of the "reverend" who wants to buy things from you and add alot of money for shipping aka "david godson <
