The person calling from this number will be very persistant in asking if you have a home security system. Unless yo want a stranger knowing that you do not, do not answer "NO."

I said Tom, I'll tell you how I am, I am TIRED of seeing your name and number on my caller ID and would like to be removed from your list - didn't give him a chance to say anything else - I hung up - we'll see what tomorrow brings
