Voice over Internet Protocol (VoIP) is one way people are making and receiving telephone calls using an Internet connection rather than a regular phone line. VoIP services can also be attacked by computer viruses, worms, or spam over Internet telephony (SPIT). Here is how it works: VoIP converts your phone call — actually, the voice signal from your phone — into a digital signal that travels over the Internet to the person you are calling. If you are calling a plain old telephone number, the signal is converted back at the other end. If you’re comfortable with new technology, you may want to learn more about VoIP. It’s smart to do some research on this technology before signing up for it.
