Sangoma Solves Industry-Wide Fax Quality and Reliability Issue on T1/E1 Digital Phone Systems

Soft PBX Users With T1/E1 Lines Can Now Use Them For Reliable Faxing

TORONTO, ONTARIO--(June 4, 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 created the industry's first cost-effective solution supporting fax over PC-based T1/E1 digital phone systems.

Until now, users of Asterisk® and other PC-based systems with T1/E1 connections needed a separate external analog line at an additional cost if they wanted reliable fax service. Fax machines connected to a PBX using T1/E1 connections would run inconsistently at best because the analog interface supporting the fax machine was not synchronized with the PSTN timing.

"Sangoma's latest firmware revisions include an option for the analog card to receive its clocking from a T1/E1 card via a simple two-connector cable," says Sangoma Technologies' CEO David Mandelstam. "Because the T1/E1 card runs on the network clocking, the analog card that connects the fax machine to the network also becomes completely synchronized, allowing for perfect, error-free faxing without any of the glitches caused by imperfect timing.

"Fax connectivity remains an absolute requirement for businesses, especially for mission critical documents like legal contracts," adds Mandelstam. "This breakthrough allows larger offices to make proper use of the T1/E1 lines that they are paying for without having to purchase and manage additional analog capacity just to support faxing."

Sangoma's fax solution is software agnostic and works with any operating system or application, including Asterisk®, FreeSwitchTM, CallWeaverTM, OPALTM and YateTM. All T1/E1 cards with hardware echo cancellation shipping after June 1, 2007 will have synchronous fax support enabled. This solution also solves similar issues with modem transmission.
