Findings from industry analysts, Juniper Research found that the VoIP market will contribute 32 billion, out of a market worth $260 billion, by 2009 (some 12 per cent of total telephony revenues).

Ian Cox, broadband specialist, said “VoIP brings new revenue generating opportunities to the telephony market, by combining voice services with other IP applications. This will redefine the telephone bringing brand new services, with telephony at its core.” The challenge to service providers will be to carefully manage this convergence, balancing new VoIP revenues against declines in traditional fixed line revenues. Flat-rate IP-based voice tariffs will gradually replace time and distance related tariffs.

The initial residential use of VoIP will be via a “PSTN-bypass” through a PSTN interconnect (this excludes free PC-to-PC or peer-to-peer services, that do not offer PSTN interconnect). However in the longer term voice will be offered as part of a service bundle that includes email, Internet access and video telephony. This will be the fastest growing segment by 2009.

For the business user calls using an adaptor will be the largest segment, although significant growth in the IP-PBX and IP-Centrex markets will occur. Calls from IP-VPNs will also grow quickly as enterprises take advantage of network convergence to reduce costs.
