Sangoma Releases Transcoding Gateway Appliance

TORONTO, ONTARIO–(Marketwire – May 2, 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, today announced the release of its NetBorder Transcoding Gateway, the latest product in the growing range of gateway appliances to serve enterprises worldwide. This new gateway facilitates the interconnection of Voice over IP (VoIP) devices and networks with support for transcoding between a wide range of codecs-from low-bandwidth to High Definition (HD)-that are employed throughout the rapidly growing enterprise communications landscape.

“The ability to efficiently complete calls that use disparate codecs without degrading voice quality is becoming increasingly important to customers that rely on VoIP systems,” said Adam Sherman chief technical officer of Versature, Inc. located in Ottawa, Canada. Versature has been beta testing the NetBorder Transcoding Gateway in their network for a number of weeks. “Sangoma’s Transcoding Gateway provides us with a powerful tool to satisfy the interworking needs of customers in a single appliance. It allows users to benefit from the recent codec advancements in enhancing call quality and reducing bandwidth without worrying about the complexities of codec compatibility.”

The new NetBorder Transcoding Gateway provides bandwidth savings in interoffice VoIP and SIP trunking deployments with support for narrowband G.723.1 and G.729 codecs. Additionally, the appliance enables seamless connections between various SIP implementations such as those using different RTP packet sizes.

Beyond delivering bandwidth efficiency, the Transcoding Gateway offers many options for consistently high voice quality. In addition to the wide variety of narrowband codecs, support for HD voice codecs such as G.722 and G.722.1 makes it possible for HD and non-HD compliant devices to interoperate. On networks that are susceptible to packet loss, and the attending degradation of voice quality, more resilient codecs such as iLBC can be used to improve the performance and deliver solid call quality.

Available as a 1U appliance, the NetBorder Transcoding Gateway allows transcoding between any supported codec from a wide range including, iLBC, GSM-FR and as well as all common SIP and HD voice formats. These can be selected on a per call basis allowing for complete flexibility and the gateway can support up to 4000 simultaneous SIP sessions. The appliance provides very low latency processing to ensure low-jitter and excellent call quality.

“Transcoding operations are very processor intensive and can completely cripple other functionalities in typical server based systems,” said Julien Nephtali, product manager for Sangoma. “The use of a dedicated appliance mitigates these potential impacts and efficiently delivers the transcoding that is becoming ever more necessary as users take advantage of the benefits offered by the latest codec technology today and going forward.”

Sangoma provides an industry-leading solution portfolio that enables the interworking of a wide variety of disparate TDM and IP networks, clouds, protocols, services, devices, and applications. Its portfolio includes award-winning voice and data boards, transcoding and gateway software, and standalone gateway appliances, designed for simple integration with open source and closed source IP PBX applications, Contact Centers, Unified Communications Systems and Service Provider Networks.
