Mavenir Innovations Gains Momentum as Top-Five Leader in Mobile IMS Market

RICHARDSON, Texas, March 23, 2010 - In the growing IMS (IP Multimedia Subsystem) market that is expected to
reach US$1.44 billion by 2014, Mavenir Systems, a provider of innovative
mobile convergence solutions, has carved out a top market-share position.
According to market research firm Infonetics Research in its fourth quarter
(4Q09) IMS Equipment and Subscribers market share and forecast report,
Mavenir had seven percent of worldwide IMS CSCF revenues, supported by
growing revenues in Mobile Voice, Instant Messaging and Presence application
server.

According to Shubh Agarwal, Mavenir's Vice President of Marketing, the
company's market position is driven largely by their innovative approach
adopted across three commercial deployments. Mavenir customers are planning
to launch services ranging from voice and messaging services over IP devices
such as Femtocells, Converged IP Messaging (CPM) and Rich Communications
Suite (RCS) services enhanced with SMS/MMS interworking and Social Networks
aggregation. Mavenir IMS solutions lower costs with legacy core
infrastructure replacement and optimizes voice routing.

"Our focus is to enable new, revenue generating mobile services utilizing
our application servers with IMS as a service enabling framework. We
differentiate by blending IMS with legacy and web based services to super
charge the operator value proposition as they transform their networks to all
IP," said Agarwal. "We are pleased to be recognized for our sales growth, and
will continue to work with our key partners and customers to further
strengthen our market position in this growing space."

"The shining star in 4Q09 for IMS sales were deployments for mobile
networks, particularly purchases for RCS, LTE trials, and enhanced mobile IM
and presence services — all areas of focus for Mavenir," said Diane Myers,
Directing Analyst, Service Provider VoIP and IMS, Infonetics Research.
"Mavenir is well positioned to gain from the overall momentum of the IMS
market that will be driven by mobile operators starting with RCS in 2010 and
Voice over LTE in 2013."
