Unknown and unsolicited caller at 8:33 am. Left a very low voice message which was garbled by handset noise. The man was whispering, sounded like a teen aged prank caller except the voice sounded much older. Was able to make out the words recent law in california ... dialer ... then some mumbling before a loud and very clear "REALLY?", some more unintelligible mumbling and the "F" curseword.
