Caller didn't leave a message on my machine and the caller id said "AEDHS" which has no meaning at all [Googled it] so it is probably a 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 Santa Ana, California with 2 service providers of USA Mobility Wireless Inc. and Peerless Network of California, LLC-CA, which are both favored by scammers, that are associated with this number. This is definitely a scammer that is either spoofing numbers or using a VoIP System to phish for personal information while running some type of scam. 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.
