RENO, NV--(Marketwire - February 23, 2010) -  Synergy Research Group announces the publication of Q4 2009 and YE 2009 market shares. The worldwide market for Enterprise Voice totaled just under $10 billion for full year 2009. Year over year, the market fell over 25 percent; however the second half of 2009 showed solid improvement across all voice segments with network upgrades providing positive momentum. With the challenging economic environment some vendors fared better than others navigating through increased competition and tightened customer spending.

IP Telephony (IPT) continues to be the fastest growing segment of the Enterprise Voice market -- which includes IP-only and Converged IP/TDM PBX phone systems and IP Phones. In 2009, IPT represented nearly 70 percent of the total Telephony market, with the remainder comprised of the legacy markets of PBXs and KTS.

Market share gains in 2009 were difficult at best with 9 vendors gaining share and 7 vendors losing.

"In looking at different regions, we see the advantages of regional strength come in to play. For example, in the U.S. the top gainers were Cisco, Avaya, Siemens, and ShoreTel," said Jeremy Duke, Principal Analyst and Founder, Synergy Research Group. "In comparison, the top market share gainers in EMEA were Alcatel-Lucent, Avaya, Siemens, Aastra, and Mitel."

Another interesting area includes the growing market of IP Phones. Although Cisco is the lion-share holder of the market, it continues to see its share under attack. In 2009, Cisco lost nearly 2 market share points to the competition. The biggest market share gainers for IP phones in 2009 included Polycom, Alcatel-Lucent, and Avaya.
