VoIP - Voice over Internet Protocol
|
VoIP is a technology that allows telephone calls to be made over computer networks like the Internet. VoIP converts analog voice signals into digital data packets and supports real-time, two-way transmission of conversations using Internet Protocol (IP). |

VoIP calls can be made on the Internet using a VoIP service provider and standard computer audio systems. Alternatively, some service providers support VoIP through ordinary telephones that use special adapters to connect to a home computer network. Many VoIP implementations are based on the H.323 technology standard. Website Builder
VoIP offers a substantial cost savings
over traditional long distance telephone calls. The
main disadvantage of VoIP is, like cell phones, a
greater potential for dropped calls and generally
lesser voice quality.

Traditionally VOIP

Traditionally, telephone calls are carried through Public Switched Telephone Networks (PSTN), which provides high-quality voice transmission between two or more parties. On the other hand, data such as email, web browsing etc. are carried over packet-based data networks like IP, ATM and Frame Relay. In the last few years, there has been a rapid shift towards using data networks to carry both the telephone calls and the data. This so called convergence of voice and data networks is very appealing due to many considerations. LayoutBank's Website Templates
