"Call display spoofing" and "call spoofing" are almost the same thing. They represent a service that comes into your life offering you and your family privacy and safety. Call display spoofing simply offers you the great ability to change what appears on someone's phone display when that someone receives a phone call from you. With this ability, the call display spoofing service offers phone number anonymity so you wouldn't have to give away your real phone number every time you make a call.

Call display spoofing emerged a couple of years ago and it has been helping private investigators and law enforcement with the call spoofing tools they need to perform their jobs much more effectively than before. They would use the call display spoofing system for a "pretext call", a phone call on which the private investigators solicit valuable information under a deceptive guise.

Call display spoofing uses VOIP(Voice Over Internet Protocol) technology. VOIP is a system that allows phone calls over an Internet connection. Using a private and secure channel, call display spoofing service transfers phone calls from the usual phone carrier to the Internet. Another part of the call display spoofing system is that when you dial a number using the system, you can put on your called person's phone display any phone number you wish. This is why some people don't think that call spoofing should be legal because it allows pranksters to make silly jokes on their friends or relatives. But this kind of manifestation of some who use call display spoofing is far away from any type of harassment and this is really not a good reason to put the system in the illegal part.
