Just got another call from this number, got 2 yesterday. I never get a person when I answer it, I just hear a click noise after saying "hello?" a few times, like they hung up or I was disconnected.
I just tried calling the number back and was connected to the sales office of the Minneapolis Star Tribune newspaper. They said they've been having issues with their phones. Regardless, it's telemarketing, 'cause as soon as I got that explanation, they threw the pitch at me.
