Received call at 5:56 am CDT on Saturday, 9/26/09. I did not answer call in time - no message left, just a hang-up tone on voicemail. Resent receiving call at that hour from anyone I don't know - my immediate reaction was there had been a family emergency. The area code reflects CA origin - that means west coast is receiving calls at 4:00 am. If it's a renegade predictive dialer, they need to shut it down!
