Sangoma is releasing a new version of the drivers for its BRI cards that significantly improves the performance of its cards with Asterisk.

The Sangoma A500 ISDN boards can be expanded from 2 to 24 BRI ports and are available in both PCI and PCI express models. It has, like all Sangoma hardware, a life time warranty. In addition the cards autosense PCI bus voltage so they work with 5v or 3.3v motherboards.

The new development of Dahdi BRI integration means that customers will now have the choice to use the A500 boards with software echo cancellation or with hardware echo cancellation, providing more options.

This significantly improves the cost performance of the Sangoma cards at a factor of 35% less than our echo cancellation cards.
