Called with ID Out of Area, which is funny as I am in 480 and this is 602 same county same metro area.  Must think we are stupid.  Just blocked at least won't be bothering me again.  

Same here, no I.D., said 1 or 2 words to machine and hung up, This was my 4th. annoying call so far today. I am on Do Not Call List, but it's useless.

Just called me too.  Disconnected when they got the machine.

Unwanted call...third time...we answer and they hang up

Husband answered by mistake, some guy rattles off something about our air conditioner & husband couldn't understand him.  I P.U. the other phone & asked what the call was for - Man said he was just calling to let us know that we qualify for a new air conditioner.  Told him we weren't interested & we have an AC co. to call when WE'RE ready.
I'd think a legit place would show their name on the caller ID & not 'Unknown name'.  So I figure it's some sort of scam to get info from ppl.

Said he was from someplace like 'hoffman configurations' and was 'helping' out homeowners by coming out and doing the annual maintenance on their air conditioners.

I just got one as well. No voice on the other end

Received call from this number; no caller ID, no message.  Unrecognized.

I also just got a call.
