Sangoma Releases ISDN BRI Card for World Markets

Sangoma's A500 BRI Card Supports Asterisk® And Other Open Source Telephony Projects

STOCKHOLM, SWEDEN and TORONTO, ONTARIO--(Marketwire - June 11, 2007) - Sangoma Technologies Corporation (TSX VENTURE:STC), a leading provider of connectivity hardware and software products including VoIP, TDM voice, WANs and Internet infrastructure, has released its new A500 BRI card designed to support the European and global open source telephony markets.

"Our A500 BRI card was developed in response to the continuing world market demand for a quality BRI that works flawlessly when connected to any ISDN switch," says Sangoma Technologies president and CEO David Mandelstam. "The solution uses a well-tested and widely-certified ISDN code set, ensuring full resolution of connection issues that have plagued BRI connectivity on open source telephony systems up until now."

The BRI fully supports the ISDN S/T bus as either an NT or TE device using a reversed module design that avoids jumpers. Distinctive features include:

- Expandable from 2 to 24 ports of 2B+D interfaces for a total of 48 ISDN channels

- PCI or PCI Express bus support

- Optional carrier-grade echo cancellation

- Support for all open source telephony projects

"Over the years we have built our business by developing hardware that simply works, the first time," adds Mandelstam. "As an integral part of Sangoma's AFT design family, the new A500 inherits the compatibility, enhanced performance and reliability of its siblings."

The A500 supports the same digital processing and highly-compatible PCI/PCI Express interfaces as the AFT series. It provides the benefits of hardware-based echo cancellation and voice enhancement for scalability for various installations.

The card will enter full production in mid-July.

Sangoma continues to bring innovation, scalability and higher density solutions to market at the request of its enterprise and telco customers. Sangoma's current solution set can be found at:
