No reports yet on this one so I'll be first.  CID just says "unknown call CA" - well don't be too obvious huh, that's a tipoff.  No msg left.  Now blocked.

Caller didn’t leave a message on my machine and the caller id said “XXXXXXXXXX, CA” which probably means scammer/telemarketer since every legitimate business I know leaves a message. So I ran 3 reverse traces using 3 types of traces and all were completely blocked. No person or business name, a general location of Gravesboro, California which nowhere near the actual area code of 714 in Orange County, California and no service providers showed up but multiple OCN listings came up. A legitimate business would never hide their identity and location by blocking a trace. This is the worse kind of scammer that is probably operating from a foreign country that is either spoofing dead phone numbers and/or using a Voip system while phishing for personal information and running a scam(s) (i.e. Microsoft or Mac Tech or Rep claiming you have a virus etc.). This is an extremely high tech scammer so beware.  DO NOT ANSWER AND DO NOT CALL BACK FOR ANY REASON. Block and report to the proper authorities.

The guy just called three times. No message left. I called back and a guy answered saying he is 911 highway patrol. I told the guy you just called me three times, he said it might be my phone provider.. Scammer

Marie, this is a spoofed number.
The "511" exchange does not exist in the 714 or in any other geographical area code.
The numbers "211" - "311" - "411" - "511" - "611" - "711" - "811" and  "911" are reserved and cannot be used as area codes or exchange numbers.

When you dialed the number, the phone company simply connected you to the 511 service in the 714 area code, which, in your area, went to the police.
