• Responsible for:
  guidance on the end-to-end transmission performance of networks, terminals and their interactions, in relation to the perceived quality and acceptance by users of text, speech, and image applications. This work includes the related transmission implications of all networks (e.g., those based on PDH, SDH, ATM and IP) and all telecommunications terminals (e.g., handset, hands-free, headset, mobile, audiovisual, and interactive voice response).
  
  
• Lead Study Group on Quality of Service and performance
  As Lead ITU-T Study Group on Quality-of-Service (QoS) and Performance, Study Group 12 provides leadership for the ITU-T in dealing with QOS-related issues. Internal to the ITU-T, this leadership involves providing a roadmap for QOS activities that can be used to identify and resolve QoS-related issues across Study Groups. External to the ITU-T, this leadership involves active communication with other organisations, with a goal of improving the visibility of ITU-T expertise in QoS and more effectively leveraging this expertise in specifications being developed elsewhere in the industry.
