Sangoma Commences Shipments of SBC

TORONTO, ONTARIO--(Marketwire - May 17, 2012) - Sangoma Technologies Corporation (TSX VENTURE:STC), a leading provider of hardware and software components that enable or enhance IP Communications Systems for both voice and data, announced that commercial shipments of its highly-anticipated Vega 400 SBC standalone Session Border Controller (SBC) appliance commenced today. The solution is designed to provide seamless connectivity between Voice over IP (VoIP) networks and SIP Trunking connections, while delivering security and policy enforcement to ensure call quality and reliability.

"The Vega 400 SBC squarely addresses the need for SIP Trunking and IP network interconnectivity that is becoming increasingly critical to the fundamental security and operation of business communications networks," said Simon Horton, director of product management for Sangoma. "It is designed to be a cost-effective, reliable solution for customers that must contend with the policy and security issues that routinely come up when integrating disparate IP infrastructures. The appliance supports from 12 to 60 simultaneous SIP sessions, making the Vega 400 SBC an excellent fit for any deployment."

Bridging the gap between disparate IP networks or systems, the Vega 400 SBC provides encryption of media and signaling, as well as call access control, secure network logon and secure management interfaces. In addition to its security functions, the SBC provides a broad range of intermediation and core VoIP capabilities necessary to ensure proper call handling and call quality. This includes a wide array of audio codecs, and the capacity to perform real-time transcoding when necessary to facilitate call media handling. Key VoIP call quality measures and features enable the device to provide many VoIP gateway functions, such as adaptive jitter removal, comfort noise generation and silence suppression, QoS statistics reporting and hardware-based echo cancellation. In addition, Sangoma offers customers a lifetime guarantee on Vega 400 SBC appliances, further enhancing the value of this offering.

"As we work with our customers to integrate more network segments, we are seeing a steady increase in the demand for SBC capabilities as a fundamental part of the networking solution," said Toan Quang Nguyen, chief executive officer of DQN Co Ltd., a key Sangoma distributor in Vietnam. "The Vega 400 SBC enables us to easily address any border management needs with a device that we know carries the quality and reliability that Sangoma has delivered in its products for years."

"The Vega 400 SBC is just one of eight new products launched already this fiscal year, and we aren't slowing down a bit," said William Wignall, Sangoma president and chief executive officer. "Sangoma's strategy to expand its portfolio of solutions to address the real business needs of today's telecom customers has yielded unprecedented successes in recent quarters as evidenced by our recent reporting of all-time record revenue in the 3^rd fiscal quarter ending March 31.
