LightEdge Deploys Acme Packet for Delivering Hosted Unified Communications Service to SMBs

Acme Packet Net-Net SBC Streamlines and Simplifies Delivery of Service Based on
BroadSoft and Microsoft Solutions
BURLINGTON, Mass.--(Business Wire)--
Acme Packet (NASDAQ: APKT), the leader in session border control solutions,
today announced that LightEdge, the leading hosted services provider dedicated
to the communications and IT needs of small and medium-sized businesses (SMBs),
has deployed Acme Packet`s Net-Net session border controller (SBC) to deliver
its recently-announced Hosted Unified Communications, a new service based on
BroadSoft`s BroadWorks Voice-over-IP (VoIP) application platform as well as
Microsoft Solution for Hosted Messaging and Collaboration. LightEdge deployed
Acme Packet SBCs to simplify new customer activation and enable "click-to-call"
functionality in tandem with the BroadSoft platform.

The LightEdge service provides one platform for voice, email, instant messaging
and calendaring, allowing a user to collaborate in real-time within the office
and outside the office. Hosted Unified Communications is part of the LightEdge
Connected Office suite of products, and helps SMBs more easily and
cost-effectively obtain unified communications (UC) as a hosted service.
LightEdge Connected Office suite includes Microsoft Exchange Server 2007 for
hosted email, BroadSoft BroadWorks Hosted PBX VoIP, Microsoft Office
Communications Server 2007 for instant messaging and presence, Microsoft Live
Meeting and Microsoft Windows SharePoint Services 3.0. The solution can be
purchased incrementally or as an entire integrated bundle to support a business`
e-mail, calendaring, conferencing, voice and collaboration needs.

Acme Packet`s Net-Net SBC was deployed in the LightEdge network to help simplify
the process of activating new customers. The SBC's ability to enable seamless
communications for LightEdge customers by mediating and controlling signaling
flows between SIP phones and LightEdge service elements reduces interoperability
issues, leading to shorter service activation cycles with fewer trouble tickets
and higher customer satisfaction.

The Net-Net SBC also works in tandem with the BroadSoft platform to enable
"click-to-call," a feature of the LightEdge service that provides end users with
the ability to initiate or receive VoIP calls simply by clicking a button on
their desktop. Because the Acme Packet SBC can effectively manipulate SIP
messages, LightEdge can offer click-to-call or other features that boost
productivity and improve the business communications experience for LightEdge
customers.

"Our customers expect strong ease of use from our Hosted Unified Communications
service," said Jeff Springborn, president and COO of LightEdge. "Acme Packet`s
SBCs enable that while giving us the ability to offer a very high-quality
integrated user experience."

"The integration of hosted voice with existing desktop applications offers a
huge opportunity for increasing overall business efficiency," said Dino Di
Palma, vice president of sales and business development at Acme Packet.
"LightEdge`s use of our SBCs further validates the business benefits of
supplementing basic VoIP and UC functions with advanced session border control."
