Acme Packet safeguards True Corporation’s VoIP network

BURLINGTON, MA, JUNE 26, 2008 — Acme Packet® (NASDAQ: APKT), the leader in session border control solutions, today announced that True Corporation, Thailand’s only fully integrated communications service provider and the largest broadband provider in the country, has deployed Acme Packet Net-Net® session border controllers (SBCs) for wholesale peering interconnects, IP PBX trunking and residential VoIP. The Net-Net SBCs are deployed in Bangkok using SIP and H.323 signaling protocols. Acme Packet’s multiservice architecture maximizes service reach and security at the access and peering interconnect borders of True’s VoIP network.

Acme Packet’s SBC provides an extensive feature set to protect and optimize True’s VoIP network. Denial of service (DoS) attack prevention, topology hiding and access control lists keep unauthorized and malicious traffic from breaching the network’s core. To maximize service reach, adaptive hosted NAT traversal eliminates the roadblocks to incoming calls created by premise-based NAT/firewalls. Acme Packet’s equipment is field-proven with most VoIP products and has features that can solve many interoperability issues, enabling True Corporation to maximize its service reach with peering partners. Acme Packet helps optimize network efficiency and cost with the Net-Net SBC’s least cost routing (LCR) feature, which enables selection of the most appropriate peering partner based upon various metrics, including cost, time of day and available bandwidth.

“In order to deliver our VoIP services that match our demands and our customers’ expectations for security and quality, we needed a session border controller that fits our requirements for interoperability, as well as network security and control features,” said Dr. Jay Jootar, assistant director, head of VoIP business at True Corporation. “With Acme Packet, we are able to deliver secure, advanced IP communications to residents, businesses and wholesalers, utilizing the Net-Net SBC’s multiservice architecture that protects both our peering and access borders.”

“True is bringing IP interactive communications to the Thailand market and our SBC plays a key role in making its service offering secure, high quality and scalable,” explained Seamus Hourihan, vice president of marketing and product management for Acme Packet. “True recognizes these characteristics as essential to being successful with its new service offerings.”
