Research firm Dell’Oro Group has released a report that predicts IP telephony carrier market revenue will grow from $1.6 billion in 2004 to $4.7 billion in 2010.
The “5-Year Forecast Report” notes sales of Class 5 subscriber access products now complement the sales of Class 4 trunk networks that drove the early years of next-generation network equipment sales.
Dell’Oro Group said sales of both Class 4 and Class 5 solutions will climb as the upgrade of the circuit-switched PSTN to the IP-based NGN accelerates over the next several years.
"Service providers' transition to Voice over Internet Protocol (VoIP) is part of their broader network transformation to all-IP networks that deliver expanded services via broadband connections," said Steve Raab, director of IP telephony research at Dell'Oro Group. "Today's residential and business VoIP services will expand to include fixed-mobile-convergence, multimedia services and gaming as service providers adopt the emerging IP Multimedia System architecture.”
