Calls come in at all hours of the day. When I call the number back I get a message that the call cannot be completed as dialed. I suspect that they recorded this message from the telco and are using it on their incoming message
Same thing happened to me when someone i know was arrested for being an illegal immigrant. When i received this phone call it was them trying to contact me, i went through the steps the voice recording was talking about but still was never able to actually speak to this individual. Did i give information to a telephone fraud operation at a coincidental time when someone close to me was arrested?
