Increasing momentum in the VoIP market has seen it finally move beyond the 'early adopter' stage. International VoIP calls grew from 0.2% of telephone traffic in 1998 to 10.4% in 2002 - Broadwatch News Analysis. Gartner goes on to note that IP telephone systems accounted for just 1.4% of total business telephony equipment sales in 1999. However, in 2003 IP telephony equipment increased its market share to 56% of all sales, and by 2007, it is expected to account for 97% of all business telephony sales.

Ability to increase revenues and economic feasibility are the main factors for the sharp increase in the adoption of VoIP by the service providers and telecom companies. Analysys predicts that provisioning of value added services to SME customers will result in telecom operators adding EUR25 000 per year in 2008 to their ARPU. Further, deployment of VoIP networks involve 30% less Setup and deployment costs.
