Caller didn't leave a message on my machine and the caller id said "SURVEY" 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 Tucson, Arizona using a service provider of Qwest Corporation which is a favorite for scammers. This is definitely a scammer that is either spoofing and/or using a voip system to phish for personal information while running some scam(i.e. Take a survey for a free Bahaman Cruise Vacation etc.). 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.

NOTE: Here is the contact information for this numbers service provider.
