I got a call from this number, picked up and asked, "Hello, who's calling please?" Some sounds, then a man says hello and asks if it's (salutation) (part of my surname). I told him "Your name is 'hello'?" - then I told him he needs to learn how to make a phone call, that he needs to be listening when the person he calls picks up and answers. I hung up. No call backs so far, a few minutes.
