Internet Telephony From Asia’s Perspective
● Growth for Internet Telephony may continue in some
countries for some time where
o Tariff differential persists and
o Broadband network is growing substantially
● In other countries; conventional telecom services
are the focus because of:o New entrants in conventional voice (as a result of deregulation)
o Substantial tariff reduction for Fixed and Cellular
o Tremendous growth of cellular sector

Worries and Hopes for Telcos
Telcos are worried because● Consumer in saturated markets require versatility of services through
single access point
● EBIDTA margins are squeezing particularly in growing markets because of declining tariffs and penetration to low end consumer
As a result● They are looking for more avenues where
o Multiple services could be offered on single platform
o Operating cost is reduced
o Call delivery could be done more efficiently
The advent of Next Generation Network (NGN) has become the future hope
7
NGN According to ITU
● A Next Generation Network in general is ao Packet based network which can provide telecomm. services
o make use of multiple broadband access technologies
o QoS-enabled transport technologies
● Offers unrestricted access by users to different service providers
● In terms of technical characteristicso A single IP-based core network handling full range of services
o Is multi service access node supporting full range of access services
o Distributed switching, routing and network intelligence enabling remote control and access

Regulating
VoIP Interconnection
11
Widely Accepted Regulatory Objectives
● Protecting consumer rights and interest
● Ensuring fair competition to promoteo efficient supply of telecom services
o good quality of service
o efficient prices
● Optimize use of scarce resource such radio
spectrum
12
Major Regulatory Challenges in IP
Environment
● Implementation of standardized networks
(Ensuring implementation of internationally accepted interoperable standards being technology neutral)
● Interconnect Agreements (redraft) to take into accounto Determination of call termination charge
o Service Level Agreement (SLA)
● Ensuring QoS
● Minimizing cost of termination
(Establishment of Interconnect Exchange or Peering House)

Interconnect Rate in IP Environment
● No benchmarks are available
● FAC or LRIC may become obsolete
● Interconnect rate in IP environment will take into account the following factors:o Network elements
(Core network and transmission network to continue)
o Minutes of usage (disregarding distance)
(IPCDRs can mention start and end time)
o QoS (Delay, Packet loss etc.)
(IPCDRs hold QoS info: )
o High risk on NGN investments may result in higher WACC because of
- Higher Market Risk will cause higher cost of equity
- High cost of debt – Banks are likely to provide financing on higher rate
Cost Of Equity: Re = Rf + β (Beta) * (Rm - Rf)
• Re Return on Equity
• Rf Risk free return
• Rm Market Risk
• β Systematic Risk factor (The relative risk of
stock with respect to the reference market
WACC = Rd D/V * (1-Tc) + Re * E/V
• Rd Cost of Debt
• Re Return on Equity
• D Value of Debt
• E Value of Equity
• V Total Value of the company, D+E
• Tc Corporate Tax Rate
15
QoS and SLA
● QoS of VoIP may remain a question mark for some time
Thus
● SLA must be part of interconnect agreements as o acceptable QoS parameters to be defined
(Max. packet loss and delay)
o Implementation of QoS and fixing responsibility for failure is possible
(based on IPCDRs which hold QoS info)
16
Interconnect Exchange and Clearing House
Given that the cost of establishing a bilateral VoIP-
peering arrangement is too high
● The IP based Interconnect Exchange (IE) is the
natural outcome in IP environment
In Turn
● Interconnect Billing Clearing House (IBCH)
becomes a reality by adding gateway feature to IE (thus reducing billing reconciliation issues among the
operators)
17
Stakeholders Readiness
Network Operators
● Operators of Japan, Hong Kong, Singapore and
China are quite advanced in NGN deployment
● PTCL the incumbent Fixed line operator in Pakistan
has announced an ambitious FTH rollout plan
Regulators
● IDA of Singapore, OFTA of Hong Kong and TRAI of
India are pursuing consultation process quite
aggressively
● Not much activity in other countries
