Abstract / Excerpt:

VoIP audio conferencing has become one of the major business tools today. Participants of a conference connect to a Multipoint Connection Unit (MCU) that facilitates connectivity, audio mixing and audio packet unicasting. The current and widely used conferencing scheme today uses MCU equipment to facilitate a centralized audio conference. However, these equipment do not reach all areas of the world to allow participants in these areas to join conferences and enable audio conferencing. A solution to this problem is to create a decentralized audio conferencing scheme that will eliminate the limitations of using MCU equipment. However, the current decentralized audio conferencing scheme that requires a component of the MCU, which is the Multipoint Controller, to reside in one of the participants, and probably different equipment, poses more limitations due to its complexity. This paper discussing the current VoIP audio conferencing schemes, their limitations, and the proposed alternative decentralized VoIP audio conferencing scheme that will use VoIP terminals enabled with MCU capabilities. This paper also discusses a methodology for creating an MCU-Enabled VoIP softphone that will be used to start, connect, and maintain a decentralized audio conference.
