P bypass revenue is expected to remain essentially flat at USD 30 billion while total international call revenue jumps to about USD 160 billion. 39 In this view, of the 96 billion Asian international calling minutes of use forecast in 2011, only around 25%, some 22.8 billion minutes, would be attributable to VoIP. However looking at recent growth (33% of all minutes effectively since around 2001), expected regional economic development (around 6-8% per annum) and the rollout of better quality technology for VoIP in Asia, projections of both overall call volume and proportion of VoIP seem low, when taking account the low cost of calling and the expansion of trade, offshoring and migration of workforces. Lowering costs could accelerate international telephone traffic (as VoIP) by a minimum of 10-20% per annum as new consumers enter the disposable income bracket (suggested as 24% per annum in China) for international low cost calls.

TELECOMS INFRASTRUCTURE TO 2030 compensation for the loss in voice revenues it might possibly be expected that prices for fixed lines would increase and that operators would introduce flat rate unlimited voice packages. However, raising prices for fixed lines would tend to accelerate the migration towards mobile for the ordinary consumer. Government and private sector roles in the markets-led model Private sector-led growth in infrastructure investment has revolutionised access to telecommunications services around the world over the past ten years. For the OECD community we see that deregulation has allowed new pricing regimes, not controlled by the incumbents, and specifically the VoIP market to take off, despite attempts to ban or restrict it in some countries. However in developing countries, two competing assumptions regarding the build of telecommunications infrastructure are that "the private sector alone is enough" and "the government must take the lead role." Obviously,
