This person just breathed on my answering machine for over two minutes. It was really creepy. It's maybe an email provider number but defiantly an Internet phone number. I read you can get a number off some of the email providers then they can just drop the number and use another. It showed on my phone as +30 57973960. This is no Florida number i do believe you can pick any number from these lists. These people must be mentally or emotionally disturbed to be as cowardly as to hide there numbers.
