Called this morning. Caller ID showed "out of area," yet I live in the 352 area code, so I was immediately suspicious. I answered (was expecting a call) and it turned out to be some home security outfit that was "going to be in the area giving away 20 GE security systems"--not further identified. The confusing part was I couldn't tell if it was a real person on the line or a sophisticated robo-caller. If I stayed on the line I might have been able to figure it out, but since I already gave myself away as a live number, I didn't want to compound the mistake. After checking the number, it comes up as "subscriber number for the given number is invalid," so I have to assume it's bogus.
Like Steve, I'm in the 352 area code. Didn't recognize the # in the first place & was a little suspicious of an exchange that started with a zero in the second place, so I didn't pick up. The caller left no message.
