Concept of Voice over Internet Protocol (VoIP) Voice over Internet Protocol‚ commonly known as VoIP‚ is a technology used for the transmission of voice information using the Internet Protocol (IP). VoIP allows the sending of voice information in a digital form using packets as opposed to the traditional circuit-committed protocols of the Public Switched Telephone network (PSTN). Traditionally when one wishes to make a phone call‚ a call is placed using a telephone that is connected to a circuit-switched

throughout the country. Electricity is in demand just about everywhere in the civilized world‚ and in Great Britain the network for supplying this electrical power is known commonly as the National Grid. The National Grid is an electric power transmission network which connects the substations and power stations. This is so that any electrical energy generated in Great Britain‚ can be utilized and help meet energy demands elsewhere. This grid system also includes interconnections that run under
