Has to be a scam. No message left even though the machine picked up. Caller ID was clearly suspicious: "OXFORD PA" (pushing the text to the edges of the screen). Tried calling back on a different phone and got the "We do not recognize this number" message (so trying to harvest working #s). And one of the two hits on Google was some site with bogus names that was from LESOTHO (!). DO NOT PICK UP!
