MONTREAL, QUEBEC--(CCNMatthews - May 24, 2005) - Sangoma Technologies Corporation (TSX VENTURE:STC) (www.sangoma.com), a leading provider of connectivity hardware and software products for TDM voice, WANs and Internet infrastructure, announced today they have chosen Octasic Inc. (www.octasic.com) for use in their high density E1/T1/J1 Advanced Flexible Telecommunications (AFT) series solution supporting voice and data.

Sangoma's new A108d (eight E1/T1/J1 port), A104d (four E1/T1/J1 port) and A102d (dual E1/T1/J1 port) cards with DSP support in hardware will use Octasic technology to provide board-level voice quality enhancement features including echo cancellation, audio conferencing and tone detection. The range of cards will provide hardware DSP support for new and existing Asterisk™ installations, as well as supporting other PC-based PBX systems.

"Octasic products integrated with our AFT range of cards will not only result in dramatic reductions in CPU load for soft PBX systems, but will also provide the highest quality voice support in the business," says David Mandelstam, CEO of Sangoma Technologies. "The combined technology will make it possible to handle several hundred calls per server, all with significantly improved voice quality and system reliability."

"Octasic developed its technology for traditional carrier class equipment which is one of the most demanding environments for efficiency and voice quality," explains Frederic Bourget, Director of Product Management at Octasic. "Today, with the advent of VoIP, delivering high quality voice processing has become an issue for all voice equipment suppliers. Sangoma was able to quickly develop a product that leads the market in features and quality. This achievement is a testament to Octasic's capabilities to handle PC based enterprise requirements and to Sangoma's leading engineering."
