This article discusses a 2006 "Business Communications Review" article entitled "IP-Telephony System Market Chugging Along" that forecasted that Cisco was likely to overtake Avaya and Nortel for private branch exchange (PBX) market leadership, despite a smaller installed base to which it could market and sell its Internet protocol IP-centric system solution. The author describes how Cisco's first half-market share (23 percent) is several points ahead of Avaya and is likely to increase by another point by the end of 2007, based on shipment trend data. Though Cisco's global market is not as strong as its U.S. share, they continue to catch up to the leaders.
