Voice
over Internet Protocol, is a method for taking analog
audio signals, like the kind you hear when you talk on the phone,
and turning them into digital data that can be transmitted
over the Internet. VoIP can turn a standard
Internet connection into a way to place free phone calls.
The practical upshot of this is that by using some of the free VoIP
software that is available to make Internet phone calls, you are bypassing
the phone company (and its charges) entirely.
VoIP is a revolutionary technology that has the potential
to completely rework the world's phone systems |
