NEWS RELEASE: Sangoma Hardware Selected By Pandora Networks As An Integral Part Of On Demand IP Communications Solution

Sangoma Technologies Continues To Extend Leadership Position In Managed VoIP Networking Space

Toronto, ON - August 2, 2005 - Sangoma Technologies Corporation (TSXV: STC) (www.sangoma.com), a leading provider of connectivity hardware and software products for VoIP, TDM voice, WANs and Internet infrastructure, announced Pandora Networks (www.pandoranetworks.com) has selected Sangoma's AFT Series of TDM hardware as an integral part of its On Demand IP communications solution. Based in Emeryville, California, and established in 2001, Pandora Networks has developed WorkSmartTM, an On Demand IP communications solution to improve business communications.

Capable of handling both voice and data and supporting all popular open source projects, Sangoma's AFT Cards offer a new market standard for performance, reliability, compatibility, support, and ease of installation. With less demand on the host CPU, drivers take advantage of the AFT technology to substantially reduce the processing required to handle TDM voice calls. This reduces the CPU's workload and results in fewer dropped calls, less jitter and better voice quality for callers.

AFT card features:

Compatible and Flexible - Sangoma's voice/data cards are self-sensing for 3.3v and 5v PCI slots and software configurable for T1, E1 or J1. They share interrupts properly between themselves and other PCI compatible devices, supporting unlimited numbers of cards per PC chassis. Conforming to the 2U form factor, both in height and length, the AFT cards allow users to install many cards in a slimline 2U chassis to maximize server capacity.

High performance - Sangoma cards have been carefully designed to reduce CPU loads in TDM environments, improving system performance and reliability on larger systems.

Trust and quality - As part of its commitment to quality assurance, each Sangoma card is individually inspected and burned-in prior to shipment in protective anti-static wrap complete with cables, manuals and CDs. The result is an almost zero dead on-arrival rate and high reliability in service.

Unparalleled support - Sangoma's fully engaged engineering support for both its hardware and software is unrivalled in the industry
