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. ....etc

VoIP, or Voice over Internet Protocol refers to sending voice and fax phone calls over data networks, particularly the Internet. This technology offers cost savings by making more efficient use of the existing network.
Traditionally, voice and data were carried over separate networks optimized to suit the differing characteristics of voice and data traffic. With advances in technology, it is now possible to carry voice and data over the same networks whilst still catering for the different characteristics required by voice and data.

Definition
Using an ordinary phone for most people is a common daily occurrence as is listening to your favorite CD containing the digitally recorded music. It is only a small extension to these technologies in having your voice transmitted in data packets. The transmission of voice in the phone network was done originally using an analog signal but this has been replaced in much of the world by digital networks. Although many of our phones are still analog, the network that carries that voice has become digital.

In todays phone networks, t ....etc

Voice over IP The protocol specification

Abstract
IP telephony, known in the industry as Voice-over IP (VoIP), is the transmission of tele-phone calls over a data network like one of the many networks that make up the Internet. VoIP involves sending voice transmissions as data packets using the Internet Protocol (IP). In VoIP, user's voice is converted into digital signal, compressed and broken do ....etc

VoDSL

The VoDSL (Voice over DSL) decodes signaling messages that are exchanged over VoDSL network and protocols used over LES ATM-AAL2 links. The main purpose of the signaling messages are to allocate AAL2 channels, activate user IAD ports, manage the customer premises IAD through the EOC management channel and to set and release POTS and ISDN calls. The whole concept of VoDSL is to support multiple voice calls, either inbound or outbound, over a single DSL circuit, while simultaneously supporting high speed Internet access. VoDSL is based o ....etc
