IP Telephony Carrier market revenue is poised to grow from $1.6 billion in 2004 to a whopping $4.7 billion in 2010; this is what analysts from research firm Dell'Oro Group concluded after conducting a recent study.

 

According to the findings, "sales of Class 5 subscriber access solutions now complement the sales of Class 4 trunk networks that drove the early years of Next Generation Network Equipment (NGN) sales."

 

Analysts are also forecasting that accelerated sales of both Class 4 and Class 5 systems will go up as carriers opt to upgrade circuit-switched PSTN to the IP-based NGN over the next several years.

 

"Service Providers' transition to VoIP is part of their broader network transformation to all-IP networks that deliver expanded services via broadband connections," noted 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 (IMS) architecture," concluded Raab.
