Caller didn't leave a message on my machine and the caller id said "Out of Area". I ran 3 separate reverse traces and all were blocked for a person(s) or a business name and 2 of them were blocked for a location, the 3rd came back with Anaheim, California (with no address) and the only one to show a service provider of BROADVOX - CLEC, LLC-CA. This caller is definitely a scammer and probably a hacker. BROADVOX -CLEC (Competitive Local Exchange Carrier) is teamed with ONVOY which sells Voip systems and provides customers but this caller blocked caller id which is not what a legitimate business practices. A legitimate business would never hide their identity and location from the public by blocking. Do not call back for any reason. Block and report to the proper authorities.
