| Abstract;It is essential to develop methods for evaluating, designing, and managing the quality of service (QoS) of IP (Internet protocol) telephony. Here, we introduce recent standardization activities in ITU-T SG12 (International Telecommunication Union, Telecommunication Standardization Sector, Study Group 12), which is studying the end-to-end transmission performance of networks and terminals, from the view-points of QoS assessment and IP telephony management, as well as the transmission characteristics of terminals.
