Sangoma Technologies Supports Development Of Yate 
Telephony Project Under Windows

TORONTO, ONTARIO--(CCNMatthews - April 26, 2005) - 

Sangoma's Support Opens the Windows Market for the Yate PBX and IVR 
Project 

Sangoma Technologies Corporation (TSX VENTURE:STC) (www.sangoma.com), a 
leading provider of connectivity hardware and software products 
supporting voice transport, WANs and Internet infrastructure, and the 
Null Team Company (www.null.ro), primary developer of Yate, announced 
today an agreement to develop a Windows-based version of the 
GPL-licensed Yate telephony project.

Yate is a next-generation telephony engine. While the project currently 
supports VoIP/ telephony gateways and Interactive Voice Response (IVR), 
its power lies in its scalability. Voice, video, data and instant 
messaging can all run independently under Yate's flexible routing engine 
while interacting through a unified messaging system.

"Most commercial IVR applications such as call centers are 
Windows-based. This open source initiative will free developers from 
reliance on hard-to-use, proprietary solutions based on expensive 
hardware," says Sangoma Technologies President and CEO David Mandelstam. 
"Recognizing the inherent strengths of the Yate model we have offered 
our technical and financial assistance to offer this project to the 
large market that is dominated by Windows. We expect to take a 
leadership role as we support the project for the developer community."

"Yate for Windows provides the first open solution for Windows-based 
clients requiring integrated, customized telephony systems," says Diana 
Cionoiu the leader of the YATE project. "Because of the modular nature, 
stability and scalability of Yate, it is a natural integration platform 
for the developers of high quality open source telephony-related 
software."
