VoIP Telephony

VoIP telephony applications treat voice calls 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 Voice over IP protocols, and demodulated at the destination.
