SANGOMA TECHNOLOGIES A108 Card Provides Industry’s Highest Density T1/E1 Solution for Voice and Data

TORONTO – May 10, 2006 – Sangoma Technologies Corporation (TSXV: STC) (www.sangoma.com), a leading provider of connectivity hardware and software products for VoIP, TDM voice, WANs and Internet infrastructure, has introduced its new A108 Series PCI cards to support high density voice and data applications. At 8 T1/E1 ports, the A108 has the highest T1/E1 density available on a PCI card.

As with other Sangoma PCI cards, the A108 is available in an A108d version especially built for the soft telephony industry. The A108d supports voice enhancement capabilities including G.168-2002 echo cancellation with 1024 tap/128ms tail per channel on all channel densities, DMF encoding/decoding and tone recognition, voice quality enhancement and adaptive noise reduction.

“We brought this high density product to market at the request of our enterprise and telco customers who require scalability and higher density solutions,” says Sangoma Technologies President and CEO David Mandelstam. “We continue to meet the flexibility and system needs of the industry with the launch of our new 8-port card.”

Distinctive A108d features include:

• Support for 1024 taps (128ms) of echo tail handling on every channel (DS0) meaning that troublesome delayed echoes are properly handled.
• Dynamic and selective activation of echo cancellation, making the system ideal for mixed voice/data applications.
• The same PCI interface, architecture and digital path as all of Sangoma’s other AFT based analog and T1/E1 cards, meaning that the A108 has guaranteed stability, motherboard compatibility issues and proper interrupt handling.
