Description

We guarantee that our card, working directly with DAHDI (no patch required), delivers the same sound quality and performance as the DigiumTM and SangomaTM cards while costing considerably less.

PRI cards today became a commodity since all manufacturers use FPGAs and the same OctassicTM DSP for their Echo Cancellation. Not only our cards perform at par with the larger manufacturers but they also offer the Innovative and Unique PCI/PCIe Rotation System (see video). Available in 1,2,4 and 8 port, use this card with any of the major open source platforms.
