1st Gen E1/T1 PRI CARD (PCI/PCIe)
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.
