VoIP is a term used in IP telephony for managing the delivery of digital voice information sent in discrete packets using the Internet Protocol, rather than traditional circuit-committed protocols of public telephone networks. The new technology of sending voice information in digital form is addressed completely in Testing Integrated QoS of VoIP: Packets to Perceptual Voice Quality, which details the techniques of testing VoIP networks to ensure quality of service. It also includes information on reducing one-way delay, jitter, and data loss for VoIP traffic while retaining the performance of other business-critical network applications.
