BEDFORD, MA, OCTOBER 4, 2011—Acme Packet® (NASDAQ:APKT), the leader in session delivery network solutions, today announced successful participation in the VoLTE Interoperability Event 2011, organized by the MultiService Forum (MSF) and backed by the GSMA. At the event Acme Packet’s session border controllers and policy exchange controllers provided SIP and Diameter signaling controls at access and interconnect borders as well as the core network.

The multi-vendor interoperability test environment was designed by the MSF to test key service concepts in IP Multimedia Subsystem (IMS) and LTE networks. This event offers service providers third-party validation so that they may purchase vendor products with confidence that they will meet the interoperability standards set forth by the global standards organizations.

Acme Packet demonstrated the capability of its Net-Net® session border controller (SBC) and Net-Net Policy Director in VoLTE networks in both home and roaming environments. The test cases included Voice over LTE (compliant to GSMA PRD IR.92) and roaming and interconnect (compliant to GSMA PRD's IR.65 and IR.88). Acme Packet participated in both locations, the Vodafone Centre for Test and Innovation in Düsseldorf and the China Mobile Research Institute Lab in Beijing.

Acme Packet’s VoLTE and 4G multimedia communications solution is headed by the Net-Net Session Director. In the VoLTE interoperability event, Net-Net Session Directors fulfilled multiple Third Generation Partnership Project (3GPP) IMS functional requirements—the Proxy-Call Session Control Function (P-CSCF) and IMS-Access Gateway (AGW) functions at the access edge of the IMS network; and the Interconnect-Border Control Function (I-BCF) and Transition Gateway (TrGW) at the interconnect border. Acme Packet SBCs provide critical functions for VoLTE service delivery, encompassing security, service reach maximization, SLA assurance, revenue and cost management and regulatory compliance. In VoLTE roaming scenarios, Acme Packet SBCs can provide the Visited-P-CSCF with flexibility to anchor media remotely or route media to the home network.

At both MSF test locations, the Net-Net Policy Director was used as a 3GPP Diameter Routing Agent (DRA), providing critical security, interoperability and routing functions for Diameter signaling. These functions streamline networks and ensure resiliency for LTE and IMS networks. The Net-Net Policy Director was used for both core Diameter routing and VoLTE roaming.

This participation complements Acme Packet’s position as one of the leading IMS vendors with nearly 120 active projects globally and recognition in Infonetics Research reports as a top three IMS brand for two years running. Acme Packet will be showcasing its VoLTE solution at 4G World in Chicago October 25th-27th.
“Acme Packet’s commitment to the VoLTE interoperability event, alongside Vodafone and China Mobile, highlights the significance of the combination of IMS and LTE for the telecommunications industry,” said Kyu-Ou Lee, MSF President. “The MSF and GSMA are working together to validate the standards to benefit the vendor and service provider ecosystem.”

“The MSF VoLTE interoperability event is invaluable to Acme Packet and our customers as we work together to make next generation voice and IP multimedia communications a reality for LTE networks,” explained Patrick MeLampy, chief technology officer and co-founder of Acme Packet. “We build our solutions to meet important industry standards and widely interoperate with the multitude of client and core vendors so that service providers can build networks with the greatest confidence and choice.”
