Avaya Leads Worldwide Unified Communications Market in Key Industry Report

New Dell'Oro Group Report on Enterprise Telephony Includes Debut of UC Market Research; Places Avaya as Global Leader in $3.1 Billion UC Market for Third Quarter of 2008


BASKING RIDGE, NJ--(Marketwire - December 3, 2008) - Avaya Inc., a global provider of business communications applications, systems and services, leads the worldwide unified communications (UC) market in revenues, according to a new Dell'Oro Group Enterprise Telephony Report.

This is the first time the Dell'Oro Group -- a research firm that provides market information about the networking and telecommunications industries -- included unified communications research in its quarterly report on the enterprise telephony market and its vendors. According to the report, Avaya led in unified communications revenues in the third quarter of 2008 with 22 percent of the global market share, more than 3 points ahead of its nearest competitor. The total market in revenues for UC in the third quarter was $3.1 billion, according to Dell'Oro Group.

Unified Communications is defined by Dell'Oro Group as the integration of voice with other modes of real-time communications, including instant messaging, video and multi-party collaboration, as well as e-mail and messaging. UC market share is measured by Dell'Oro Group as an overlay to its enterprise telephony report in order to assess the market from a real-time collaboration perspective. Other vendors tracked in Dell'Oro Group's UC research included Cisco, Nortel, Alcatel-Lucent, Siemens and Microsoft.

"It is reasonable to believe that unified communications will be the next disruptive technology," said Alan Weckel, director, Dell'Oro Group. "UC is bringing functions that have historically been confined to core PBX hardware into software applications. The companies that can lead in this transition -- and deliver the responsive, real-time communications features that companies want -- are best positioned to compete in the new era of business communications."

Dell'Oro Group's report also measured third quarter 2008 results for the worldwide Total PBX market, a category that includes Internet protocol (IP) telephony, traditional TDM technology and hybrid telephony combining both IP and TDM technologies. Their report concluded that Avaya led the Total PBX market in revenues with 20 percent market share, 6 points ahead of its nearest competitor. This marks the fifteenth consecutive quarter that Avaya has led in the overall enterprise telephony market, based on Dell'Oro Group's reports.

Avaya's enterprise telephony and unified communications solutions are powered by Avaya Communication Manager, a business communications software platform that helps organizations easily evolve their infrastructure to help enhance business user productivity and customer service experiences.
