Mavenir Announces Trio of Products to Rapidly Launch Voice over LTE Services

mOne(TM) Convergence Platform Provides Readiness for LTE Services Launch

RICHARDSON, Texas, May 13, 2011 - Mavenir Systems, the leading innovator of mobile infrastructure solutions
for LTE operators, today announced the VoLTE Edition of its mOne(TM)
Convergence Platform. Available now, the Mavenir mOne(TM) Convergence
Platform - VoLTE Edition provides operators with three options for quickly
and cost-effectively deploying voice and messaging services over LTE.

Currently, some LTE operators are planning to support voice using the
Circuit Switched Fall Back (CSFB) standard with plans to migrate to the VoLTE
standard to support Multimedia Telephony (MMTEL) services, while others plan
to deploy MMTEL directly. Either way, operators face deployment challenges
such as MSC upgrades, service parity and other operational complexities,
affecting their ability to launch LTE services quickly and evolve their
network to support multiple options.

Mavenir's mOne(TM) Convergence Platform - VoLTE Edition provides
operators with a trio of products for overcoming deployment challenges:

    - The CSFB Inter Working Function (CSFB IWF) product enables
      the delivery of voice and SMS to CSFB devices, without requiring any
      changes to the existing Mobile Switching Center (MSC). This eliminates
      major operational complexities resulting in reduced costs, faster
      service availability and better user experience.
    - The MSC based Telephony Application Server (TAS) leverages an
      operator's existing MSC and all its services in an IMS environment to
      deliver voice to VoLTE compliant devices. It allows operators to
      rapidly launch VoLTE without incurring major network upgrade costs.
      The solution was previously announced in a partnership with Acme
      Packet to deliver mobile services over Wi-Fi or broadband devices.
    - The Mobile TAS solution delivers MMTEL services to VoLTE
      compliant devices, to support enhanced voice and video services in an
      all-IP domain. The Mavenir Mobile TAS supports native Intelligent
      Network (IN) services and integrated Mobility Application Server to
      help mobile operators preserve critical revenue generating features
      such as prepaid, ring back tones and mobility.

"Mavenir's approach minimizes the cost, complexity and time to market for
LTE services, expands LTE operators' revenue opportunities and enhances their
competitive position. Multiple operators have deployed our products in
anticipation of voice capable LTE devices and service launch," said Pardeep
Kohli, president and chief executive officer of Mavenir Systems. "Mavenir's
solution gives LTE operators the best of both worlds: the ability to capture
the market for broadband data services while catering to users who value
voice and SMS."

The Mavenir mOne(TM) Convergence Platform is a common foundation that
adapts as the service evolves, simplifying the operator's network
transformation. Deployment can start with the option that is feasible or
practical to launch services immediately, and a simple software upgrade to
MMTEL is available whenever the operator is ready.

At the LTE World Summit in Amsterdam, Mavenir will be speaking on VoLTE
deployments. Contact marketing@mavenir.com to set up appointments or visit at
