The international telecommunications industry has seemed to be on the verge of adopting VoIP in a big way for years. Research company In-Stat on Monday produced a report that says the ramp up to mass migration will happen within a decade.The mass VoIP adoption period for consumer and small business is 2005-2009, while migration to VoIP will peak in the 2010-2014 time frame, the high tech market research firm says. This time frame is largely dependent on carriers’ strategies for migration to the Next-Generation Network (NGN). “A carrier’s NGN migration strategy is heavily influenced by factors such as the cost of maintaining the Public Switched Telephone Networks (PSTN), available investment funds, technology, regulatory policies, pricing trends and competi-tion,” says Keith Nissen, In-Stat analyst. “Each carrier will develop its own unique NGN migration strategy.” Carriers around the world are developing migration strategies that include network optimization, next-generation overlays and PSTN replacement, In-Stat says. These strategies will directly impact the type, quantity and timing of future equipment purchases. In-Stat has concluded that as VoIP competition and de-mand increases over the next five years, incumbent carriers will increasingly opt for PSTN replacement to lower operating costs. The migration to VoIP depends on carriers migrating to next-generation network architectures such as IMS IP multimedia subsystem). The In-Stat report profiles selected carriers to illustrate alternative network migration strategies. The business and market factors driving these various strategies are examined. Network migration strategies are forecasted for each incumbent operator, worldwide, leading to the quantification of global VoIP-enabled lines from 2005-2019. Technology Industry
