Abstract

Over the past decade, the telecommunications industry has witnessed rapid changes in the way people and organizations communicate. Many of these changes spring from the explosive growth of the Internet and from applications based on the Internet Protocol (IP). The Internet has become a ubiquitous means of communication, and the total amount of packet-based network traffic has quickly surpassed traditional voice (circuit-switched) network traffic. In the wake of these technology advancements, it has become clear to telecommunications carriers, companies, and vendors that voice traffic and services will be one of the next major applications to take full advantage of IP. This expectation is based on the impact of a new set of technologies generally referred to as voice over IP (VoIP) or IP telephony. 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). There are three basic protocols which are used to implement a voice over IP solution: H.323, SIP and RTP. H.323 and SIP are mainly concerned with the call establishment and voice encoding, whereas RTP (Real-time Transport Protocol) is used by both protocols for the transport of encoded voice packets over an IP network. This paper is intended to study the technology and its benefits, characteristics, protocols, architectures, differentiates with traditional PSTN, all the hardware and software both the IP technology and its applications, and how Malaysia are approaching IP-enabled technologies, particularly VoIP, and the implement issues surrounding VoIP. In addition, this study case will include the latest technology that support VoIP like VoIP with WIFI, and also satellite.
