Boiler room for a company marketing for ADT.  When I asked if they had a business relationship the caller hung up.  Called the number back got an answering machine.  Asked to be put on their Do Not Call List as we are on the National Do Not Call List.

Someone keeps calling me from this number but never leaves a message. It is a local area code. When I called I got a recorded message saying I could leave my name and number and someone would return my call. Security system sales call. I will be reporting them to the Do Not Call Registry.
