Sangoma Technologies Partners With Halo Kwadrat; A 
Specialized Channel Partner In Europe

TORONTO, ONTARIO--(CCNMatthews - Nov. 17, 2004) - 

Partnership To Exploit Growing European Asterisk Market And Extend 
Sangoma Technologies' Global Reach

Sangoma Technologies Corporation (TSXV:STC) (www.sangoma.com), a leading 
provider of connectivity hardware and software products for WANs and 
Internet infrastructure, has partnered with Halo Kwadrat 
(www.asterisk.com.pl), of Warsaw, Poland as a distributor of Sangoma's 
voice and data A101, A102 and A104 T1/E1 solutions for Time Division 
Multiplexing (TDM) voice applications in Europe.

"We see a burgeoning market for our TDM voice delivery platforms all 
over the world," says Sangoma Technologies CEO David Mandelstam. "By 
partnering with Halo Kwadrat, we now have the opportunity to extend our 
presence in Europe with a partner who understands the market and is well 
known to the local soft PBX community."

The first Open Source software PBX implementation supported on Sangoma 
hardware is the Asterisk project. Asterisk is a complete PBX in 
software. It runs on Linux and provides many telecommunications features 
including voice over IP (VoIP). The Asterisk system interoperates with 
almost all standards-based telephony equipment using highly cost 
effective hardware such as Sangoma's AFT series T1/E1 WAN cards.

"We will leverage our strategic relationships with our vast network of 
contacts in the Asterisk space to strengthen Sangoma's market position," 
adds Halo Kwadrat's vice-president Michal Bielicki. "Sangoma's decision 
to partner with Halo Kwadrat has been reinforced by the rapid 
development of a reseller network which includes among others Espia of 
Italy (www.espia.it), Speakup (www.speakup.nl) of the Netherlands and 
Convergence of Pakistan (www.convergence.com.pk).

Sangoma Technologies' current solution set includes:

- WANPIPE(R) internal media gateways, transporting TDM voice, IP data 
and video over T3/E3, T1/E1, ADSL and serial links
