Acme Packet® (NASDAQ: APKT), the leader in session border control solutions, today announced that Impsat Fiber Networks, Inc. has deployed Acme Packet’s Net-Net® session border controllers (SBCs) to deliver its family of VoIP products for the mid and large corporate market and VoIP interconnects for wholesale services to carriers. Impsat, a leading competitive operator in Latin America, has already deployed Acme Packet’s Net-Net SBCs as part of its voice network in Argentina, Brazil, Peru and the US with plans to expand further in 2007.

Acme Packet’s Net Net products support a broad range of interactive communications applications at multiple network border points, providing key control functions in the areas of security, service reach, SLA assurance and revenue and profit protection. With Acme Packet’s solutions deployed, Impsat is able to deliver a robust suite of premium IP interactive communication services, as well as create a choice of tiered services designed to match specific customer needs and budget.

“We required a secure and controllable way to allow our services to seamlessly traverse disparate networks to support both our business IP communication services and the interconnect services we provide to other providers,” said Guillermo Mármora, Vice President of Technology and Operations, Telephony at Impsat Fiber Networks. “Acme Packet’s unique ability to support both access and interconnect services gives us a strategic advantage by requiring only one network element to support both service types. As we continue to expand our VoIP network across Latin America, the Net-Net SBCs help us reach more customers securely and with high quality levels.”

In particular, Impsat uses Acme Packet’s adaptive NAT traversal capabilities and broad protocol support including SIP to H.323 interworking abilities to maximize the reach of its services. The Net-Net SBC session and admission control features help assure service quality and adhere to service level agreement assurance. Additionally, Acme Packet’s advanced Net-SAFE security features help ensure the integrity of the Impsat network by providing preventative measures against denial of service (DoS) and other malicious attacks.

“With an advanced network architecture that spans seven Latin American countries and the US, Impsat is a leading integrated broadband voice and data service provider,” said Seamus Hourihan, vice president of marketing and product management of Acme Packet.  “Acme Packet provides a key solution designed to give Impsat a competitive edge in delivering trusted, first class IP interactive communications services to its business and wholesale service provider customers.”
