Caller didn't leave a message on my machine and the caller id said "VOIP Caller" which usually means telemarketer/scammer. So I ran 3 reverse traces using 3 different types of traces and all were blocked for a person or business name and the only information was a general location of Anaheim, California using a service provider of 01 Communications, Inc-CA which is a popular choice for scammers using voip systems since they sell them and provide the phone service too. This is definitely a scammer. A legitimate business would never hide their identity and location from the public by blocking a trace. DON'T 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 are making money from them by providing the systems and services that these scammers use and possibly farming out numbers too.
