The Future Paradigm of VoIP Services  

Kim, Byung-Ho (경성대학교 컴퓨터공학과)
Abstract
It has been 10 years long since the emergence of Dialpad, the first commercial VoIP service from Saerome Technology launched on 1999. In spite of so many research papers and implementations of the VoIP and commercial services with hundreds of VoIP-related products vendors and tens of VoIP service providers during the last decade, the resulting market share of the VoIP callings at the year 2007 in Korea is just about 0.3%, which is extraordinary lower one than expected. There have been proposed several facts for the reason including the QoS issue and the incomplete governing system. In this paper we suggest that the reason is based on the sociocultural issue and further we assert and verify that it can never replace the existing legacy telephone system for the current VoIP service model, as long as the telecommunication companies continue the legacy telephone service. We also suggest the another choice, to upgrade the concept of the current VoIP service to a new paradigm based on SIP and presence service, while letting the legacy telephone system be as it is.
