Persistent people!!! I hung up once and they called back. I told them to stop calling and hung up again.  At a latter time, they left a message on my phone to call 876-875-3451 to claim 2.5 million in a mega milllion win.

Scammers call primarily elderly victims and urge them to "call back" at this 876 number.  Locally, the scam was that the target had won a MegaMillions jackpot. First ploy was for the target to provide banking info (they did not) and when that failed, they said for $2,700 they'd deliver the check (again, they did not bite). Finally, the target was told if she would just call this number she'd get more information. I suspect this is one of those 900-number styled scams.
