HILLSBORO, Ore. -- February 14, 2013

Radisys^® Corporation (NASDAQ: RSYS), a market leader enabling wireless
infrastructure solutions, is partnering with Mavenir Systems, a leading
provider of software-based networking solutions, on Voice over LTE (VoLTE)
deployments based on Mavenir’s mOne^® Convergence Platform integrated with
Radisys’ Software Media Resource Function (MRF). These can both also be
deployed in virtualized cloud environments, providing scalability as operators
grow their VoLTE subscriber base. Radisys and Mavenir have secured a growing
list of VoLTE wins in both the U.S. and Europe, and are actively engaged in
multiple trials in both regions. Leading operators are expected to go live
with the joint VoLTE solution in the second half of 2013.

“The integration of our mOne^® Convergence Platform with Radisys’ MRF has
provided the economic and functional differentiation for growing commercial
success for our VoLTE and mobile service deployments, including the world’s
first VoLTE deployment at MetroPCS,” said Ian Maclean, vice president,
Strategy and Marketing, Mavenir Systems.

Operators that have rolled out LTE networks are turning to VoLTE and Rich
Communications Services (RCS) delivering High Definition (HD) voice, Video
Ringback Tones (VRBT), Interactive Voice and Video Response (IVVR),
Conferencing and other value-added services to win back revenue from
over-the-top (OTT) and content providers that have been the early
beneficiaries of LTE’s increased bandwidth and access speeds. Next-generation
IP Multimedia Subsystem (IMS) architectures, with an MRF processing real-time
audio and video media streams, are the underlying foundation supporting these

“While 2012 was the year of LTE, 2013 is shaping up to be the year of VoLTE
service rollouts,” said Phil Kendall, Director of Strategy Analytics’ Wireless
Operator Strategies program. “South Korea, Japan and the USA will lead the way
with VoLTE, though will be joined by a wave of mobile operators globally over
the next 24 months as they look to secure and evolve their communications
businesses for the next decade. We predict 1.6B LTE connections by end of
2017, and VoLTE and other mobile video services are essential for growing
revenues beyond LTE data plans. Standards-based IMS service delivery
platforms, such as Mavenir’s mOne^® Convergence Platform and Radisys’ MRF,
deliver compelling video and voice services that maximize revenue options for

Providing mobile operators with improved economics, scalability and
next-generation communications services, the deployment-proven Mavenir mOne^®
Convergence Platform addresses subscribers’ needs in a mobile market that is
changing rapidly. Offering voice, video, multimedia and social messaging, the
platform performs an integral role in subscriber growth and revenue generation
for mobile operators. Its built-in network optimization and open network
interfaces bring additional cost reduction to operators, along with
flexibility for new business models.

The collaboration of Radisys’ Software MRF and Mavenir’s mOne^® comes at an
ideal time, given the growing number of VoLTE trials underway. Radisys’
Software MRF can be deployed to run as a virtualized application with other
virtualized applications on the same server hardware in a cloud data center,
providing scalability as operators grow their VoLTE subscriber base to
accommodate increased market demand. It also comes with built-in support for
AMR-WB high definition audio codec specified for VoLTE devices, while
supporting automatic transcoding with other audio codecs that might be
necessary when connecting a VoLTE call to a 3G and PSTN device. In addition,
the Software MRF provides operators the necessary flexibility to support small
trial deployments all the way up to thousands of endpoints on a single server.

Radisys’ Software MRF shares the same capabilities as the rest of the Radisys
MRF product family. This provides Mavenir’s customers an upgrade path to the
powerful MPX-12000 Broadband MRF, based on Radisys’ T-Series ATCA platform.
The MPX-12000 has been selected and is currently undergoing final
interoperability testing for a VoLTE trial with a Tier1 operator in India.

“Enabling operators to generate new revenue through VoLTE, video value-added
services, conferencing and more is at the core of the investments we continue
to make in our MRF product portfolio,” said Amit Agarwal, vice president and
general manager, Software and Solutions, Radisys. “Our growing commercial
success with our partner Mavenir is a testament that we’ve made the right
investments. To date, Radisys’ MRF is participating in seven VoLTE trial
deployments and is clearly emerging as the undisputed global market leader of
MRF solution for VoLTE and RCS.”

Radisys will be showcasing its Media Resource Function solutions in Stand
5G34, Hall 5 at Mobile World Congress, February 25-28 in Barcelona. To
