17 Definitions Internet Telephony: In the beginning, Internet telephony simply meant the technology and techniques to let you make voice phone calls local, long distance, and international over the Internet using your PC the definition of Internet telephony is broadening day by day to include all forms of media (voice, video, image), and all forms of messaging and all variations of speed from real-time to time-delayed. IP Telephony: (As defined by Microsoft) IP Telephony is an emerging set of technologies that enables voice, data, and video collaboration over existing IP-based LANs, WANs and the Internet. Specifically, IP Telephony uses open IETF and ITU standards to move multimedia traffic over any network that uses IP (the Internet Protocol). Voice over IP (VoIP): The technology used to transmit voice conversations over a data network using the Internet Protocol. Such data network may be the Internet or a corporate Intranet, or managed networks typically used by long and local service traditional providers and ISPs that use VoIP.

18 VoIP: An information service that delivers voice communications and enables voice convergence with other data applications and devices. WHAT THE FUTURE HOLDS: Presence (Instant Messenger, Follow me) One Number / Follow Me Services IP Call Centers Universal Messaging Virtual Meetings / Collaboration (like NetMeeting) Real time language translation IP Centrex Multi-Point Videoconferencing Desktop Multimedia Push to Talk Cellular Voice Chat 18

22 VoIP s Challenges: Operational, Standards, Policy/Regulatory

23 Who Should Set Policy for Global IP Networks and VoIP? FCC? FTC? Congress? State Legislatures? National Parliaments/ Governments/ Courts? European Union? ITU? WTO? WIPO? IETF? ETSI? APEC? National Parliaments? National Parliaments? 23

24 International VoIP Policy Activity ITU Survey on Implementation of IP Telephony in Developing Countries: Countries vary in their treatment re regulation: Include VoIP/all forms in regulatory system Prohibit implementation - Not planning to regulate Some have not yet addresses these issues 35 respondents to ITU survey: Only Spain, Sudan, Singapore, Lituania, Denmark said : should not be regulated. OECD Report: More Recent Proceedings Considering VoIP / VoB Regulatory Framework US, UK, EC, Canada, Germany Anticipated Proceedings: Hong Kong, India, Australia, Singapore, Sweden Issues Arising in Proceedings and Discussions with Policy Makers Different issues emphasized outside US US focusing on regulatory framework primarily as it impacts legacy inter-carrier compensation and USO considerations Outside US, focus on regulatory framework in light of specific rights and obligations that impact customer demand, economic development, and public safety (e.g numbering resources, entry barriers, law enforcement assistance) Multilateral Interests : ITU and OECD 24

27 What WITSA Might Do to Ensure VoIP s Success Backgrounder Paper helps to frame VoIP s story Education and Briefings essential for policy makers across range of governmental agencies, NOT just regulatory agencies Be aware that legislation is underway in many countries and may limit who and how VoIP can be provided; work with others to influence legislation. Sometimes telecom legislation included VoIP; be aware that incumbents often seek to prevent anyone else from providing VoIP Business Associations and allies, such as ISP Associations, others could join together to tell VoIP s story, of economic investment, productivity, new consumer services, etc. A picture is worth a thousand words approach: work with equipment providers, or VoIP Services providers to show the technology and tell the policy story at the same time 27
