VoIP Technology Will Challenge Traditional Assumptions
and Traditional Regulatory Models
⢠âVoIPâ is more than âVoiceâ
â The Voice/ Data dichotomy is eroding rapidly
â VoIP is not simple voice, but rather a converged multimedia application that supports voice, data and video
⢠Innovation and investment by fixed and wireless operators in IP
networks will have an economic impact
⢠IP communications have the potential to disrupt the status quo
in service provider environment, elevating applications
⢠Revolutionary opportunity for consumers; evolutionary for
businesses
⢠VoIP development and regulation should follow a cellular model
rather than a traditional fixed voice model â services will

Definitions
⢠Internet Telephony: âIn the beginning, Internet telephony simply meant the technology and techniques to let you make voice phone calls â local, long distance, and international â over the Internet using your
PCâŚthe 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.â
⢠IP Telephony: (As defined by Microsoft) âIP 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).â
⢠Voice over IP (VoIP): âThe 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.â

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 / âFollow Meâ Services
⢠IP Call Centers
⢠Universal Messaging
⢠Virtual Meetings / Collaboration (like NetMeeting)
⢠Real time language translation
⢠IP Centrex

International VoIP Policy Activity
⢠More Recent Proceedings Considering VoIP / VoB Regulatory Framework
â US, UK, EC, Canada, Germany
⢠Anticipated Proceedings:
â Hong Kong, India, Australia, Singapore, Sweden
⢠Issues Arising in Proceedings and Discussions with Policy Makers
â Different issues emphasized outside US
â US focusing on âregulatory
frameworkâ primarily as it impacts legacy inter-carrier compensation and USO considerations
â Outside US, focus on âregulatory frameworkâ 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
⢠ITU Survey on Implementation of IP Telephony in Developing Countries: Countries vary in their treatment re regulation:
â Include VoIP/all forms in regulatory system
â Prohibit implementation -Not planning to regulate
â Some have not yet addresses these issues
â 35 respondents to ITU survey: Only Spain, Sudan, Singapore, Lituania, Denmark said : should not be regulated.

What WITSA Might Do to Ensure VoIPâs Success
⢠Backgrounder Paper helps to frame VoIPâs 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 âtell VoIPâs storyâ, of economic investment, productivity, new consumer services, etc.
⢠A âpictureâ 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
