Just got a call from 989 354 5447, Alpena, Michigan.  Phone # search reveals it is a land line.  Long robo-call pause after you say "hello."  Voice asks for my husband by  name. "Is Mister . . . . John . . . Smith. . . available?"  I say, "No, he is not.  To what is this pertaining?"  And get no response.  Caller has hung up.  Guess they don't want to talk to you if you aren't the person they're asking for.  

No idea who the "company" was.  Sorry.
