This number was blocked by my app (Mr. Number) because it does not appear in my contact list. Both Mr. Number and this website confirm that the caller is not who they purport themselves to be.
Had to say "hello" a couple of times. Called asked to speak to the homeowner. I told him that this was a business line and he hung up on me. No idea what he was trying to sell me, but clearly was some sort of telemarketer since he didn't have a name to go with the number, and the number is published as my business line.
Had to say hello twice. He finally asked if I was the homeowner, never said his name or company. I said I'm the renter and what he was calling for. He abruptly hung up.
