Calls and doesn't leave a message.  Uses the phone number in the name field.  Most likely a new number used by the same 'political survey' and 'free cruise' scammers.  Likely also using 1-800-807-0812 as one of their numbers.

I received called from these number close to each other and on the same day.  Very similar noises could be heard from both when the answering machine kicked in.  Looks like we're in for yet another round of idiots calling all the time.  Sigh.

As always, never answer, and never call these numbers back: you'll just get more calls.  Ignore them, and eventually they go away.
