  2. Internet in Latin America& Caribbean (LAC) • mid-2000 to mid-2001, international Internet connectivity to Latin America & Caribbean grew 500% • Growth twice as fast as any other world region • 2,500% growth between Latin America countries • Fastest growth of anyintra-regional bandwidth Source: Telegeography, Packet Geography 2001

  6. IP Telephony: What is it? • Internet Protocol (IP) Telephony is a generic term describing voice or fax carried over IP-based networks, such as the Internet. • IP Telephony is important: • In the short-term, because it cuts the cost of calls, especially if routed over the public Internet • In the longer-term, because telecoms carriers are migrating their separate voice and data networks to converged IP-based networks • Examples of IP Telephony Service Providers include Net2Phone, Dialpad.com, iBasis, etc.

  8. IP Telephony Flavours • Often treated differently from policy or regulatory perspective • Carried solely across the public Internet • IP is underlying transport or signalling technology for PSTN services (e.g., using SS7) • IP telephony on full end-to-end “private” IP networks (e.g., using “softswitch technology”) • Combinations of the above with gateways between Internet or private IP-based networks and the PSTN

  9. Country positions on IP Telephony189 ITU Member States Unregulated, 26 countries Unregulated if not "real- time", 18 Regulated if No policy or No response 98 "real-time" 7 Light regulation 5 Prohibited 35 As of March 2001. Based on responses to ITU regulatory questionnaire and inputs to WTPF-01.

  10. Pricing IP Voice Services • In high-price, monopoly markets • Where permitted, IP Telephony creates opportunities for low-cost calls • Even if not permitted, IP Telephony is widely used to reduce costs of international call termination • In markets in transition to competition • IP Telephony offers a route towards early introduction of competition and creates downward pressure on prices • In competitive, low-price markets • Main market opportunity for IP Telephony is in value-added services, e.g., unified messaging

  11. What are the Key Issues? • Technical: • How to define IP Telephony? • Is quality of service comparable? Will it improve? • How to handle numbering/addressing issues? • Economic: • What price and cost savings can be expected? • How quickly will carriers migrate their networks? • Isn’t it just a form of bypass of telecom monopolies? • Regulatory: • Is it voice or is it data? • License it? Prohibit it? Restrict it? Liberalise it? • Should IP Telephony providers contribute to Universal Service?
