Called twice in a row. Said he is on my street installing home security systems. Told him I'm a senior on PA State and National Do Not Call lists since 2013, He hung up.
Second call from this #. Made the mistake of answering the first call on 8-3-15. He said "this is Jonathan from Home Security Systems". I said "not interested Jonathan, goodbye" and hung up. C.I.D. "unavailable".
I don't know anyone from this number so I let it ring out. This is the best tactic to deal with spam calls. Telling them you are on do-not-call accomplishes nothing.
