" Internet tariff comparisons " Wholesale IP connectivity and leased line pricing! What will be the impact of IP Telephony? " In the Asia-Pacific region " In high, medium and low-priced markets!

6 The Geography of IP! Investment in IP networks is still highly US-centric " More than 95 per cent of inter-regional IP bandwidth connectivity is to/from North America " Accelerating returns to scale means that big get bigger! Europe catching up fast " Major investment in fibre-based networks since opening up of EU markets in late 1990s! Asia-Pacific lagging behind " Top European city (Geneva) has 50 times more connectivity per inhabitant than top Asian city (Japan)! Latecomers disadvantaged by high prices " Non-liberalised telecom markets and obligation to pay both cost of both half-circuits of Int l Private Line " Insufficient demand to force down prices

10 Internet pricing and VoIP Alternative retail pricing models! Flat-rate per month " e.g., InfoCom in Uganda charges a flat-rate US$50 per month for unlimited Internet Access. To this must be added line usage and rental charges.! Usage-based " e.g., Telecom Egypt offers a premium rate 900 dialup service, without subscription or pre-payment, with revenues shared 50/50 with ISPs; " e.g., Energis in UK splits local call charge with ISP, freeserve, which advertises free Internet! Advertising-based " e.g., Hotmail offers free advertising-funded webbased service

12 Why does Internet access tend to be more expensive in developing countries?! A few exceptions " In Asia-Pacific, Malaysia is cheap but Japan expensive " But across world as a whole, US & Europe cheapest! Where there is competition " leased line prices are generally lower " incentives to create national local call ISP access " incentives for tariff innovation (e.g. free Internet)! But problems remain " Peering and transit model of Internet is very different from settlements-based model of PSTN

13 PTO = Public Telecommunications Operator Collects traffic Settlements-based traffic PTO A Delivers traffic Pays settlement fees Collects revenues Terminates traffic PTOs A & B split the cost of the int l circuit PTO B Retains revenues User 1 User 2 User 3 User 1 User 2 User 3 For accounting rate traffic, a direct bilateral relationship is established between the origin and termination operators. Intermediate transit operators are compensated from the accounting rate which is usually split 50:50. PTO B retains net settlement....

14 ISP = Internet Services Provider Internet Peering traffic (Web) ISP A One-way (thick pipe) Two-way (thin pipe) ISP B PTO B pays the full cost of the int l circuit Exchanges traffic Web 1 Web 1 Web 1 Requests and terminates traffic Collects revenues User 1 User 2 User 3 For Internet Peering traffic, ISP B pays for both halves of the International circuit(s) which are used for peering with ISP A. ISP B also pays for traffic exchange. ISP B may pay for the circuit directly, or in conjunction with one or more PTOs.

15 Internet pricing and VoIP Developing country concerns Developing country concerns! Developing countries receive no international settlement payments for IP traffic " Increasingly, incoming IP traffic includes IP telephony and fax traffic which they must terminate! They must pay to peer with US/EU backbone " Peering costs are rising as IP traffic continues to grow exponentially! They must pay both half-circuits of the International Private Line to the foreign ISP " Even though traffic flows in both directions over the circuit, once it is established! Telephone and fax traffic shifting to the Internet " What will replace the US$7 bn from settlements?

16 ITU-T T Rec. D.50: Int l Internet Connection recognizing the sovereign right of each State to regulate its telecommunication, as reflected in the Preamble to the Constitution, noting a) the rapid growth of Internet and Internet protocol-based international services; b) that international Internet connections remain subject to commercial agreements between the parties concerned; and c) that continuing technical and economic developments require ongoing studies in this area, recommends that administrations/roas involved in the provision of international Internet connections negotiate and agree to bilateral commercial arrangements enabling direct international Internet connections that take into account the possible need for compensation between them for the value of elements such as traffic flow, number of routes, geographical coverage and cost of international transmission amongst others.

17 Internet pricing and VoIP Pricing IP for voice services! In competitive, low-price markets " Main market opportunity for IP Telephony is for value-added services, e.g., unified messaging! In markets in transition to competition " IP Telephony offers a route towards early introduction of competition and creates downward pressure on prices! 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

21 IP Telephony: Four main stages of evolution 1. PC-to-PC (since 1994) " Connects multimedia PC users, simultaneously online " Cheap, good for chat, but inconvenient and low quality 2. PC-to-Phone (since 1996) " PC users make domestic and int l calls via gateway " Increasingly services are free (e.g., Dialpad.com) 3. Phone-to-Phone (since 1997) " Accounting rate bypass " Low-cost market entry (e.g., using calling cards) 4. Voice/Web integration (since 1998) " Calls to website/call centres and freephone numbers " Enhanced voice services (e.g., integrated messaging)

23 Internet pricing and VoIP The influence of Voice over IP! IDC forecasts that Web Talk revenues will reach US$16.5 bn by 2004 with 135 billion mins of traffic! Gartner Group forecast that voice over IP and competition in Europe will reduce prices by 75% by 2002! IP Telephony as % of all int l calls in 2004 " Tarifica forecast 40% " Analysys forecast 25%! In developing countries, the majority of IP Telephony calls are incoming Web Talk revenues, US$bn Source: IDC

25 ! Prices Internet pricing and VoIP Implications of IP Telephony for public telecom operators (PTOs) " To what extent has competition already reduced prices for international traffic?! Competition " Does the PTO provide IP Telephony services? " Are competitors allowed to provide IP Telephony? " What percentage of incoming int l traffic comes in as IP Telephony traffic? What loss of settlements?! Costs " Can the incumbent PTO deploy IP-based networks to reduce costs? What savings can be expected?

26 Internet pricing and VoIP Regulatory implications of IP Telephony! Allow it, license it, prohibit it? " Should IP Telephony be regarded as a service or an application? " Should incumbent PTOs be permitted to provide IP Telephony services? " Should other service providers be allowed to provide it? Should they be licensed? " Should incoming IP Telephony calls be treated any differently from outgoing ones?! Universal Service " Should IP Telephony service providers contribute towards universal service

27 Conclusions! IP is overtaking voice Internet pricing and VoIP " For PTOs, IP Telephony offers a chance to reduce operating costs and develop future-proof networks " If PTO does not adopt IP, its competitors will! ISP pricing highly competitive " Price innovation is essential " Price comparisons can help in setting prices! IP Telephony is here to stay " Incumbent carriers cannot hope to retain monopoly " IP Telephony will be used to terminate incoming calls as well as for outgoing calls
