Portugal's Second Largest Service Provider Relies upon Acme Packet Net-Net Session Border Controllers to Quickly Deliver Trusted, First Class IP Interactive Communications

BURLINGTON, Mass.--(BUSINESS WIRE)--June 26, 2008--Acme Packet(R) (NASDAQ: APKT), the leader in session border control solutions, today announced that Sonaecom, the second largest telecommunications service provider in Portugal, is leveraging Acme Packet Net-Net(R) session border controllers (SBCs) to provide security and control for its IP Multimedia Subsystem (IMS) network. The flexibility of Acme Packet's Net-Net SBCs enabled Sonaecom to rapidly roll out its residential and business VoIP services.

Sonaecom, a competitive service provider in Portugal offering fixed, mobile and converged services, has deployed Acme Packet Net-Net session border controllers as part of an Ericsson Core IMS solution. The flexibility and maturity of Acme Packet's solution, combined with its rich feature set and extensive interoperability, allowed Sonaecom to go into production with its IMS VoIP offering quickly and easily. In just two months, the company designed and tested its network with Acme Packet's Net-Net SBC and went to market with a highly secure, robust set of SIP-based services for residential and enterprise customers.

Acme Packet's Net-Net SBCs deliver a range of features for Sonaecom's network, meeting critical requirements for security, service reach maximization, SLA assurance, revenue and cost optimization and regulatory compliance. Acme Packet's Net-SAFE(R) security architecture provides Sonaecom with protection from malicious attacks and non-malicious overloads, access control and topology hiding. Call admission control policies on the Net-Net SBCs assure Sonaecom's service quality and network availability. Signaling protocol repair and header manipulation features maximize the reach of Sonaecom's IMS services. Sonaecom also plans to use Acme Packet's SBC to provide lawful intercept capabilities for call signaling and media and to query for location information using the e2 DIAMETER interface to the Connectivity Session Location and Repository Function (CLF).

It was critical that we employ a smart border solution that meets our strict requirements for security, service control and interoperability, said Jose Pinto Correia, Sonaecom's chief technical officer. With Acme Packet's Net-Net session border controllers, we not only have deployed a highly effective, mature solution, but with its flexibility, we were able to go to market with our new VoIP services faster than with other solutions.

Our SBC delivers advanced security, extensive support and rich functionality for Sonaecom's IMS network, said Seamus Hourihan, vice president of marketing and product management for Acme Packet. With our solution, Sonaecom was able to create a compelling service offering that reached more customers and differentiates itself from the competition.
