Call received on August 5, 2010 @ 11:36 a.m. No message left (SURPRISE).

Robodialer must have went on to the next number (sucker who answers).

I didn't answer this call and they didn't leave a message, the number can not be found on 411
It came in over the course of an afternoon of known scam calls, so I suspect it is one as well.
