44% of Corporate Telephone Lines Worldwide to Be IP-Based by 2008

Market Wire, 20050229

The latest study by The Radicati Group, "Corporate VoIP Market, 2004 - 2008" provides market size, four-year forecasts, IB breakdowns by business size, region, IP technology type, and competitive information for the corporate IP telephony market, including IP telephony clients.

IP telephony is poised for strong growth worldwide. Over the next four years, the number of worldwide corporate IP telephony lines will increase by over 260 million -- nearly 14 times the current installed base.

Revenue in the corporate IP telephony market will total nearly $1.0 billion in 2004. Over the next four years, this revenue will increase substantially, reaching $5.5 billion in 2008. Although overall VoIP revenue will continue to rise annually, the price per user of IP telephony will decline as the technology proliferates.

Uptake for IP telephony will be greatest in large corporations. Most of these companies will deploy Hybrid PBX systems, which include both IP and traditional TDM technology. Pure IP-PBX deployments will take place primarily in small corporations and greenfield environments.
