Infonetics Research (News - Alert), a market research firm is unveiling a just completed report, which closely analyzes virtual PBX phone systems, VoIP gateways, unified communication (UC) applications, and IP phones and has found that the industry has increased by 5.5 percent in the quarter.

According to a press release, some of the highlights of the report include the fact that the global PBX (News - Alert)/KTS phone system revenue grew in 3Q11 to $2.15 billion. In addition, when compared to the same quarter in the year prior, the global PBX market is up 6.6 percent, representing a slow yet improved period on a year-over-year basis.

Specifically in the Asia Pacific region, PBX revenue increased by 11 percent year-over-year. Findings from the research also clearly depict that more businesses are transitioning to IP-based phone systems, with hybrid IP PBXs remaining the most popular, traditional IP PBXs showing steady growth and TBM PBXs, fading away altogether slowly but surely.

"For the fourth straight quarter, Avaya (News - Alert) leads the highly competitive PBX market, with about a quarter of the world's PBX revenue in 3Q11. Avaya is holding onto its revenue lead with steady shipments and healthy ASPs due to continued increases in IP endpoint sales. Cisco (News - Alert) is a close second, posting sequential and year-over-year revenue increases in 3Q11. Cisco's overall ASPs declined in the quarter due to special promotional packages and pricing that helped spur activity," Diane Myers, directing analyst for VoIP and IMS at Infonetics Research said in a statement.
