Caller didn't leave a message on my machine and the caller id said "Out of Area" which usually means scammer. So I ran 3 reverse traces using 3 types of traces and all were blocked for a person or business name. Two locations (Buena Park and Cypress, California) and two service providers (AT&T California and Pacific Bell Telephone) were associated to this number which usually indicates a scammer that is spoofing or using a voip system to phish for personal information while running some scam. DO NOT ANSWER AND DO NOT CALL BACK FOR ANY REASON. Block and report to the proper authorities. Phone companies should be held responsible for these types of calls since they make money from them by providing the service and selling the systems (voip) these scammers use.
