IP PBX systems will almost replace traditional circuit-switched technology by 2009, according to an industry analyst.
Sales of TDM circuit-switched systems fell 11 per cent between the fourth quarter of 2005 and early 2006, and are predicted to drop a huge 88 per cent by 2009, according to the Enterprise Telephony report from Infonetics Research.
"We recently talked with 450 companies in North America about their voice infrastructure plans, and the results clearly indicate a move to VoIP which will put this market on a nice steady growth trajectory over the next few years," said Matthias Machowinski, directing analyst at Infonetics.
Annual revenue in the market is forecast to grow to $11.4bn in 2009, driven by strong worldwide IP PBX sales. IP PBX revenue is forecast to jump 82 per cent between 2005 and 2009.
The Infonetics study tracked shipments of IP deskphones and softphones, TDM PBX/KTS systems, and hybrid and pure IP PBX systems.
