RICHARDSON, Texas and BURLINGTON, Massachusetts, September 14 /PRNewswire/ --

- Partnership reduces cost, time-to-market and time-to-revenue in 
delivering legacy voice and messaging over 4G and Rich Communication Suite 
services over 3G

Mavenir Systems, provider of innovative mobile convergence solutions, and
Acme Packet(R) (Nasdaq: APKT), the leader in session border control 
solutions, today announced a reseller agreement that enables the delivery of
all of today's mobile services and new interactive communication services
over 2G, 3G and IP-based 4G mobile broadband access networks. The agreement
enables Mavenir to combine its Converged Voice and Messaging solutions with
Acme Packet's Net-Net(R) session border controllers (SBCs) to significantly
reduce the development costs, time-to-market and time-to-revenue for voice,
mobility and rich communications services delivered over fixed and mobile
broadband networks. This partnership is currently supporting two Tier 1
mobile service provider customers in Europe and North America.

Mavenir's Mobile VoIP solution extends Mobile Switching Center (MSC)
voice, intelligent network (IN) and Short Message Service (SMS), as IP
Multimedia Subsystem (IMS) application servers to offer services consistently
across multiple broadband access domains. This eliminates the need for an
overlay voice over IP (VoIP) core with potential service parity gaps,
accelerating the time-to-market. The combination of Acme Packet SBCs and
Mavenir's Converged Voice solutions also frees service providers from
deploying media gateways for networks equipped with 3GPP Release 4 MSCs,
reducing the cost and complexity of their networks significantly.

Mavenir's Rich Communications Suite (RCS) solution, combined with Acme
Packet's Proxy Call Session Control Function (P-CSCF) solution, allows
service providers to build global mobile social networks around a powerful
set of building blocks-subscriber management, presence, instant messaging,
web 2.0 services aggregation and media sharing. Presence fuels
revenue-generating services such as enhanced address book, messaging, media
sharing, gaming and voice services for both consumer and enterprise users.

Acme Packet Net-Net SBCs connect 3G and 4G mobile subscribers to IMS
SIP-based services and applications including voice, messaging, interactive
video, gaming and video. In this partnership, these services are delivered
from Mavenir mOneTM Convergence Platform. In IMS deployments, Acme Packet
SBCs integrate the P-CSCF for SIP signaling control, an Access Border Gateway
Function for media control and a Security Front-End Function for both
signaling and media. They provide the critical controls to deliver
high-quality interactive communications-voice, video and multimedia
sessions-and streaming video across 3G and 4G LTE and WiMAX access network
borders. At interconnect borders, Acme Packet's SBCs enable the seamless
exchange of VoIP and IMS services across service provider boundaries,
reducing costs and enabling new interactive communications requiring
end-to-end IP connectivity. Acme Packet's SBC control functions satisfy
requirements in five major areas-security, service reach maximization,
service level agreement (SLA) assurance, revenue and cost optimization and
regulatory compliance.

"For next-generation technologies such as LTE to be competitive, they
must be as cost-competitive as they are innovative," said Payam Maveddat,
Mavenir's Vice President of Product Management and Partnerships. "Our
relationship with Acme Packet directly addresses that need by giving
operators a powerful suite of solutions for controlling CAPEX and OPEX. Those
savings free up capital and resources to develop the innovative services that
grab market share from incumbents and drive sustainable revenue."

"Our partnership with Mavenir offers an extremely compelling approach for
delivering voice and messaging services over mobile IP broadband access
networks," said Seamus Hourihan, Acme Packet's Vice President of Marketing
and Product Management. "Our joint solution provides service providers with
the level of service consistency, cost-effectiveness and control required for
success."
