Acme Packet Extends Product Leadership in Cable VoIP Networks

ENUM Server Interface and Nominum Partnership Enables Carrier-Class Private and Public Interconnects; STUN/TURN/ICE Support Expands NAT Traversal Options

BURLINGTON, MA -- (MARKET WIRE) -- April 11, 2006 -- Acme Packet®, the leader in session border control solutions, today announced additional features and a partnership to deliver the most comprehensive collection of session border controller capabilities to enable high quality, trusted cable voice, video and multimedia services. In support of enabling carrier-class private and public interconnects, Acme Packet now supports an ENUM server interface and has proven interoperability in field deployments with Nominum's Navitas, the leading ENUM-based IP-application routing directory server. Acme Packet is also expanding its hosted NAT traversal mechanisms with support for the emerging IETF standard STUN (Simple Traversal of UDP through NATs), STUN-Relay/TURN (Traversal Using Relay NAT) and ICE (Interactive Connectivity Establishment).

Acme Packet is currently in commercial production at 4 of the top 7 cable operators in the US and at some of the top cable companies in Europe. For these operators, Acme Packet's Net-Net session border controllers (SBCs) play key roles at both access network edge and interconnect borders to protect and secure the MSO service infrastructure, maximize search reach, assure high-quality services and SLAs, protect revenue and profits, and ensure regulatory compliance.

"With over 2.2 million cable VoIP subscribers in the United States supported by our Net-Net SBCs today, Acme Packet is taking a leading role in helping MSOs deliver next generation services," stated Seamus Hourihan, Vice President Marketing and Product Management at Acme Packet. "With the addition of the ENUM interface, our new partnership with Nominum, and STUN, STUN-Relay/TURN and ICE for NAT traversal, our Net-Net SBC delivers superior feature sets for both access and peering."

ENUM support and Nominum partnership enable efficient, cost-effective VoIP transport

Acme Packet's ENUM server interface for the Net-Net SBC platforms, which supports both private and public ENUM directory services, enables MSOs to use IP transport end-to-end for VoIP calls between subscribers on different networks, eliminating any PSTN transport. Since the calls remain all IP, performance is optimized with lower latency as conversion from IP to TDM and then back to IP is avoided. Operationally, the calls are more cost effective because PSTN termination charges are eliminated. Acme Packet's ENUM interface also supports ENUM server load-balancing and active failure detection features, ensuring a carrier class and resilient solution.

Acme Packet has also demonstrated proven interoperability in field trials with Nominum's Navitas ENUM-based IP-application routing directory server. The combined solution enables service providers to implement the lowest latency and most flexible ENUM routing directory simplifying the operational model for VoIP deployment. Nominum has also joined Acme Packet's Pinnacle Partner Program to jointly offer VoIP peering solutions to the industry.

"Acme Packet and Nominum together enable secure, resilient and scalable ENUM directory services for cable operators and other service providers," said Tom Tovar, VP of Worldwide Sales and Business Development, Nominum. "Our proven interoperability and joint solution work is designed to speed the time to market for ENUM deployments and deliver what MSOs are demanding today."

STUN, STUN-Relay/TURN and ICE support increases choice in NAT traversal mechanisms

Acme Packet is also expanding its hosted NAT traversal mechanisms with support for the emerging IETF standards STUN, STUN-Relay/TURN and ICE. These IETF standards are being specified in the next-generation PacketCable architecture. Acme Packet's hardware-based implementation of STUN-Relay/TURN, enables the SBC to monitor and report QoS metrics (latency, jitter and loss) for the relayed media flows, set QoS markings and police bandwidth usage to ensure optimum control of the VoIP calls. Support of these servers in the SBC, a well-defined IP address and trusted element in the MSO's network, enhances security for a cable operator's business customers.

Support for these new IETF NAT traversal mechanisms complements Acme Packet's adaptive hosted NAT traversal mechanisms for SIP and MGCP/NCS, which are extensively deployed by Acme Packet's customers delivering hosted services. Unlike the IETF mechanisms, these existing mechanisms do not introduce any new protocols to the network or require any endpoint client software. They utilize only standard SIP and MGCP/NCS messaging and consequently can support any endpoint. Taken together, Acme Packet's NAT traversal mechanisms allow for greater implementation choice for cable operators.
