A video IP telephony service, as an enhanced service of voice over IP(VoIP) migrated from public switched telephone network (PSTN), is a representative multimedia over IP (MoIP) service of next generation network (NGN) for the mass market. Recently a leading telecommunication operator has constructed NGN and has launched a commercial video IP telephony service. This service is regarded as one of the operator's main strategic businesses together with IPTV. The operator has constructed an NGN and provided trial services during the period of broadband convergence network (BcN) project before launching commercial video IP telephony services. This paper presents analyses of trial subscribers' responses for the video IP telephony services during the BcN project period and suggests a commercial video IP telephony service strategy based on the analyses. We expect that the suggested strategy helps telecommunication providers who are ready for NGN and MoIP services over NGN for targeting the mass market.
