TORONTO, ONTARIO -- (Marketwire) -- 05/07/12 -- 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, today announced the release of its Vega 400 SBC stand-alone Session Border Controller (SBC) appliance,. 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.

"Businesses of every size rely on VoIP communications, and there is a growing demand among customers for cost-effective solutions that address the potential exposure of network vulnerabilities at inter-network junctures, such as connections to SIP trunking services," said Simon Horton, director of product management for Sangoma. "The field-proven reliability and ease-of-use inherent in the Vega Series extends to this new SBC device. It not only seamlessly and securely connects the business to the SIP trunking network, but also uses Vega's popular "quick-config" feature, which greatly simplifies the entire installation process."

"The market for enterprise session border controllers jumped 60% in 2011 and will grow significantly over the coming years as the adoption of SIP trunking continues to expand," expects Diane Myers, principal analyst for VoIP and IMS at Infonetics Research. "SBCs represent a sweet spot within the enterprise market because they fill a growing need for security, interoperability, and network border traversal."

Located between disparate IP networks or systems, the SBC helps customers contain and control vulnerabilities that can be exploited in SIP-based networks to misappropriate or misuse VoIP resources and 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 the security functions, the SBC provides a broad range of intermediation and core VoIP capabilities necessary to ensure proper call handling and call quality.

Supporting a wide range of audio codecs, the Vega 400 SBC performs 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.

"The addition of competitive SBC features to the highly-successful Vega Series of gateways is a natural step in Sangoma's strategy to expand the capabilities and functionalities of these powerful devices," concluded Horton. "With each addition of features, capabilities and services in the Vega Series, the idea of connecting anything to anything-for all types of customers-in a multi-service gateway environment, comes closer to fruition."
