Voice over IP (VoIP) applications treat voice, video, data, or facsimile as simple data, which may be packetized and transmitted in real time over IP networks. Voiceband audio is digitized at (or near) the source, the data packets are transmitted over IP networks using VoIP protocols, and demodulated at the destination.
