Vacation Scam Call.
Voice responsive female robo-voice claimed my answering machine was eligible for an expense paid vacation in Florida (Orlando and southern Florida plus a Bahamas cruise) including all meals and a rental car.  The deal broke down when my answering machine got tongue-tied and could not respond when robo-gal asked if it wanted to be transferred to an operator for all the details.
Also received the same call from (951) 800-4597
