just blocked them!

Caller didn't leave a message on my machine and the caller id said "Out of Area" which usually means this is a scammer. So I ran 3 reverse traces using 3 types of tracers and all were blocked for a name of person or business but all showed a location of Brea, California using a service provider of Global Crossing Local Services Inc.-CA. This is definitely a scammer that is either spoofing or using voip system to phish for personal information while running some kind of 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 off them by providing the services and systems these scammers use and by farming out telephone numbers.  Global Crossing Local Services Inc.-CA is not backed by the Better Business Bureau and are level 3 communications which is commonly used by scammers.

I get repeated calls from this number. They never leave a message. Finally decided to block them.

called, no message

Left no message. This number is added to my Don't Answer contact list.
Based on other reports, this call is assumed to be a telemarketer.
