Sangoma Technologies and TeleSoft International Partner to Bring the Best ISDN Access to VoIP

TORONTO, ONTARIO--(Marketwire - Sept. 2, 2010) - Sangoma Technologies Corporation (TSX VENTURE:STC), a leading provider of hardware and software enabling server-based voice and data communication applications, today announced that it has expanded its multi-year relationship with TeleSoft International to use TeleSoft's TsLink3 PRI ISDN stack in the Sangoma Media Gateway (SMG) and related products. TsLink3 ISDN software is conformant with the world standards for both the network and user sides of the North American NI-2, Lucent 5ESS & Nortel DMS100, ETSI EuroISDN and Japanese ISDN variants. PRI ISDN is currently the most popular method used by enterprise class VoIP devices to connect to the PSTN, and Sangoma's Media Gateway allows customers to quickly and easily connect to the PSTN with a proven and reliable product.

Sangoma previously used TeleSoft's software in the Netborder series of products, and they selected TeleSoft as their primary PRI ISDN provider for their current and future products because of this excellent experience. "We chose TeleSoft because our experience has been that the software just works. We don't get any calls from customers complaining about our products when using TeleSoft's ISDN," said David Mandelstam, president and CEO of Sangoma. He added, "There is an initial up-front fee but the total cost of ownership is lower than for open-source solutions, because the TeleSoft code is easy to work with, fully supported and is exceptionally reliable. Not having to fix someone else's bugs means that our engineers can work on new value-added features for our customers. This high quality makes our customers more profitable because they don't have the expense of debugging and fixing someone else's product."

"As the VoIP to PSTN market accelerates, system developers, OEMs and VARs are realizing that the most important factors determining success are high performance products that are both robust and reliable," said Chris Cox, vice president of marketing at TeleSoft International. "Sangoma products set the standard in providing the best combination of hardware and software quality in the VoIP to PSTN market and we are delighted to be a factor in their success."
