Sangoma Technologies Receives Two Technical Certifications In Russia

TORONTO, ONTARIO--(CCNMatthews - July 12, 2006) - Sangoma Technologies Corporation (TSX VENTURE:STC) (www.sangoma.com), a leading provider of connectivity hardware and software products for VoIP, TDM voice, WANs and Internet infrastructure, has received full national telecom and safety certifications in Russia for its Advanced Flexible Technology (AFT) series of T1/E1 and analogue PCI cards.

The safety certification is required by the Russian government authorizing Sangoma to sell its solutions in the region and ensures network security for end users. The national telecom certification ensures its telephony products are compatible with the country's public network infrastructure.

"Receiving these certifications in Russia is proof positive that the international, and in particular the European market, is embracing our open source telephony solution," says Sangoma Technologies president and CEO David Mandelstam. "The certifications add to the extensive portfolio of approvals Sangoma has already gained worldwide, which has eased the implementation and rollout of enabling technology-based products on a global basis."

Sangoma's AFT series has a 2U form factor (120mm x 55 mm, 4.7" x 2.2"). The 3.3v/5v PCI card supports bus-mastering, ring-buffer DMA architecture and fully shared interrupts, making it ideal for demanding environments such as the Asterisk Open Source PBX/IVR project.

The series of PCI cards supports full channelization of up to 124 individual DS0 timeslots, making it ideal for multi-channel data hub implementations and integration with PC-based VoIP PBX systems that can take advantage of this capability. Field upgradeable hardware programming allows for new functions to be added as they become available, as well as providing the capabilities for hardware-based ATM and SS7 MTP2 support.

"Sangoma's current range of digital and analogue voice PCI cards with carrier grade hardware echo cancellation and voice quality enhancement have proven to be world leaders in their class and are what developers and service providers are looking for to optimize their Asterisk and other soft PBX/VoIP applications," adds Mandelstam. "Moscow-based Traveltele.com (www.traveltele.com) helped us manage the certification process in Russia. We will now leverage our strategic relationships to strengthen Sangoma's market position in this region."
