Answer:
It's taken awhile, but now there is a technology available that can unblock private calls and numbers quick and easy.......and it's not limited to just law enforcement anymore.
The technology that will allow you to unblock or unmask private callers has just been released by the same company who makes the SpoofCard, TelTech Systems. Their new service is called TrapCall and it's used to unblock private callers.
Be careful when calling a number that you unblocked back. Take the extra precautions and block or fake your caller id number first. For more information see the web links below.
