Sangoma Brings Global PSTN Connectivity to FreeSWITCH

TORONTO, ONTARIO, Jul 23 (MARKET WIRE) --
Sangoma(R) Technologies Corporation (TSX VENTURE: STC), the premium
provider of PC-based hardware and software for proprietary and open
source networking and telephony, announced today that it will be
integrating its tested TDM stacks including BRI, PRI, SS7 with
FreeSWITCH. This will enable FreeSWITCH to reliably connect to PSTN
networks all over the world.

"This is great news for the FreeSWITCH community. The years of
collaborative work between FreeSWITCH developers and Sangoma have finally
paid off," said Anthony Minessale, Primary Author and Lead Developer of
FreeSWITCH. "This will greatly grow the FreeSWITCH community by
generating further interest from the PSTN side."

FreeSWITCH formerly only used its own Open Source stacks for PSTN access.
The Sangoma stacks make FreeSWITCH commercially reliable to service the
global market using Sangoma hardware. Speaking as a Platinum Sponsor of
ClueCon 2008 (August 5-7 in Chicago), Nenad Corbic, Chief Software
Engineer of Sangoma, will kick off the conference by discussing how
developers can take advantage of FreeSWITCH's new level of PSTN
connectivity.

"We believe this makes FreeSWITCH an excellent choice for connecting to
the PSTN," said Corbic.

"Sangoma will continue to be very active in the support of FreeSWITCH and
Open Source projects in general," said David Mandelstam, Sangoma's
President and CEO. "Our company was sewn by open source enthusiasts, and
it will always be part of our fabric."
