Voice over Internet Protocol - The Technology and Its Application
R. Joshua Samuel Raj, Abhishek Gagneja, Singal Ritika · 2012
The paper discusses the implementation of Voice over IP (VoIP). The objective of this paper is to identify and characterize the primary issues that must be addressed to define a large scale VoIP network that is capable of supporting (but not necessarily limited to) full PSTN equivalence. It presents a high-level network architecture that acts as a starting point from which PSTN equivalent VoIP networks can be built The term ―Voice over IP‖ (VoIP) describes the transport of voice over IP based networks, it is a generic term that covers deployments ranging in complexity from hobbyists using the internet to get free phone calls on a peer to peer basis or we can say end to end basis, to full scale PSTN replacement networks. Voice over Internet Protocol (VOIP) refers to the transmission of speech across data-style networks. This form of transmission is conceptually superior to conventional circuit switched communication in many ways. This publication introduces VOIP, it's working, its all features, architecture, all issues of network with network interconnection, explaining its advantages and disadvantages with applications, etc.
