International market research company Infonetics (News - Alert) just released its third quarter report, showing slow recovery for the PBX (News - Alert) telephony market. The official figures show a 5.5 percent increase in revenue to $2.15 billion, rebounding from its declines in Q1 and Q2 2011.

Top analyst of VoIP and IMS in Infonetics Diane Myers, regarding the third quarter release, said, “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.”

The PBX phone system is a type of telephonic architecture that businesses use to route calls to different departments. This system meters calls to each individual phone and has many features large businesses use to handle the large volume of incoming calls and conferences they usually receive.

Traditional PBXs have been phased out by hybrid IP-phone PBX systems and pure IP PBXs. Hybrid PBX systems account for two thirds of the market’s revenue, while pure IP systems are growing in number, accounting for one third of market revenue. Despite the quarterly decline in the first two quarters in 2011, the Q3 2011 values show a 6.6 percent recovery from the third quarter in 2010.

In Asia-Pacific, revenues from PBX phone systems showed the highest recovery, up 10 percent Y-Y from Q3 2010 to Q3 2011.
