Caller ID identified this caller as "Duct Service". The call was rejected and blocked by our call blocker, but more than likely the same group of criminals who call weekly with a new number, and are blocked every time, trying to scam homeowners and residents out of their hard earned money for bogus services.
Don't give these people the time of day by picking up the phone, you don't know them, you don't want to know them, they have nothing legitimate to offer you. They aren't ever going to abide by the terms and conditions of the DNC because they are criminals, so don't even ask to be taken off their list - they aren't going to listen to you - just ignore or block the calls.
