Infonetics Research: IMS market up 87% year-on-year; GENBAND leads combined carrier VoIP and IMS market

CAMPBELL, CA--(Marketwire - Aug 22, 2011) - Market research firm Infonetics Research today released excerpts from its second quarter 2011 (2Q11) IMS Equipment and Subscribers and Service Provider VoIP Equipment and Subscribers market share reports.

"While parts of the carrier voice over IP equipment market, specifically softswitches and gateways, are faced with ongoing declines, the IMS equipment market is experiencing the opposite, up 87% in the second quarter of 2011 compared to the same quarter a year ago. Many factors are contributing to strong IMS market growth: Large service providers in China and Europe are in the midst of significant class 5 replacement projects; subscribers are being added to existing IMS networks on an ongoing basis; and wireless operators in North America have launched IMS for messaging and plan to go live with voice over LTE (VoLTE) in 2012," notes Diane Myers, directing analyst for VoIP and IMS at Infonetics Research.


  • Global IMS (IP Multimedia Subsystem) equipment manufacturer revenue is up 20% sequentially and 87% year-over year in 2Q11
  • Alcatel-Lucent leads the fast-growing IMS session control function (CSCF) server market in 2Q11
  • In 2Q11, Asia Pacific contributed 68% of all IMS equipment spending, driven primarily by activity in China, Japan, and South Korea
  • Mobile IMS-based spending will be a strong contributor to IMS market growth in the second half of 2011, particularly in North America as operators ramp up LTE deployments and prepare for VoLTE in 2012


  • In 2Q11, the global service provider VoIP equipment market (trunk media gateways, SBCs, media servers, softswitches, voice application servers), grew 13% sequentially to $507 million
  • Year-over-year (from 2Q10 to 2Q11), the global market is down 10.4%
  • Session border controller (SBC) and voice application server (VAS) revenue is up 15% and 42% year-over-year, respectively, benefitting from the industry shift to IP and IMS
  • GENBAND leads the combined service provider VoIP and IMS equipment market in 2Q11, followed by Huawei, Alcatel-Lucent, Acme Packet, and Nokia Siemens Networks
