TSX Venture Exchange Names Sangoma to the Prestigious "2007 TSX Venture 50"

TORONTO - June 20, 2007 -- Sangoma Technologies Corporation (TSXV: STC), a leading provider of connectivity hardware and software products supporting VoIP, TDM voice, WANs and Internet infrastructure, has been named to the 2007 TSX Venture 50, a ranking of the top 50 public venture capital companies listed on TSX Venture Exchange.

This listing provides awareness to the North American investment community on the quality of companies that are listed on the Exchange and are using public venture capital to grow their companies.

"Receiving this award is important for the company because it validates the tremendous contribution our valued employees have made that have resulted in double-digit quarter-over-quarter growth rates for several years," says Sangoma Technologies president and CEO David Mandelstam. "That the TSX:V has given us this prestigious award speaks to the Sangoma's ability to maintain high growth, profitability and stability while servicing highly competitive and leading edge technologies such as PC-based voice, video and data processing. There are few companies in these markets that can match our record."

Recently announced sales and net earnings represent new all time records for the company.

"While the award was based on our financial performance to December 31, 2006, our performance since then has improved significantly," adds Mandelstam. "For instance, Sangoma's revenue grew 24 per cent in Q3 relative to our previous record Q2 numbers as new products gained traction in the marketplace. It is gratifying to see that we are increasingly meeting customer needs, resulting in our long-standing growth trend where we are growing faster than the market itself."

The 2007 TSX Venture 50 is published today across Canada in The Globe and Mail.
