I tried calling the number back (from a gmail account where I haven't signed up for a Google Voice number - thus making the call anonymous). After hearing "Your call is very important to us. You will be transferred to the next available agent" after about 30 sec, I got "Hello, this is Kevin from American Home Security" I left my mic muted and after a couple hello's he hung up. I am glad my call blocker flagged the incoming call as spam.
