Got a call today from this number. Caller identified themselves as ADT Security. I just hung up. However, when I read my Caller ID, it shows the same Phone Number in small digits in the area where a name would be. Tried to call the number back and all I got was a busy signal. Search Engines also cannot find this number to identify it.
Same thing for me. "Unknown Name" followed by the phone number in the caller i.d. They hung up on my answering machine. I try to call it back and I only get a busy signal.
