Why ACTIVE? All of the cards available on the market are called PASSIVE or DUMB cards.

The difference is that our card takes care of the majority of operation on board thus reducing the load on the CPU. Furthermore, our product is detected as a network card in both LinuxTM and WindowsTM systems.

Once the driver is installed in your system, you can start configuring the card through an easy to use interface and start using it with your preferred PBX platform (3CXTM, AsteriskTM, ElastixTM…). Hardware DSP for Line Echo Cancellation (carrier grade 128ms) and transcoding is included.

This card supports SS7 signaling and uses a DAHDI patch which is already included in our proprietary driver.

We use the exact same chipsets as the other more expensive brands but since this is the 1st gen board design, it is VERY affordable. A 128 ms hardware based Line Echo Cancellation module can be added to reach the highest standard in voice quality on the market. Build your own open source PBX system while keeping cost at a minimum. Chose from 1-2 or 4 ports with a capacity of 30 channels per port and full duplex data throughput.

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.
