DEFINITION

VoIP (voice over IP - that is, voice delivered using the Internet Protocol) is a term used in IP telephony for a set of facilities for managing the delivery of voice information using the Internet Protocol (IP). In general, this means sending voice information in digital form in discrete packets rather than in the traditional circuit-committed protocols of the public switched telephone network (PSTN). A major advantage of VoIP and Internet telephony is that it avoids the tolls charged by ordinary telephone service.

WHITE PAPERS

Voice-Enabling the Data Network, Chapter 4
This chapter focuses on how carriers are using VoIP to bundle voice and data services over a single access link to the customer. For example, traditional T1 circuits that are offered to customers to interconnect their private branch exchange PBX to interexchange carriers can now be used instead for integrated voice and data traffic, eliminating the need for multiple access links between the customer and the service provider.
