How Does VoIP Work?


Voice over Internet Protocol (VoIP) converts voice signals to a digital format, which allows the signals to travel over the Internet or private networks that use Internet technology. At the receiving end, they are converted back to ordinary voice signals. The technology allows both voice and data to travel on the same networks. In the Piedmont VoIP Pilot Project, a message can be sent from a radio by an officer from any of the participating agencies and reach another agency by way of VoIP.
