Hung up as soon as I answered.  Tried calling back and get a "all circuits are busy, please try your call again later."

Called and asked for 'Mr. Carmalli', who does not exist.  When you tell 'em it's a wrong number, they say, "Well, maybe you can help me out.", then launch into their sales pitch.  I believe this is an attempt to get around the 'Do Not Call' list.  So, whenever I get a call like this, I'll tell them that I'll call 'Mr, Carmalli' to the phone and put them on Hold.  Last guy waited 22 seconds before hanging up.
