OpenVox has now released the hardware echo cancellation modules for 2/4 port PRI cards--DE410P/E, DE210P/E. All these cards are a bundling of the relevant PRI product and the new EC100 Octasic DSP-based echo cancellation module. The EC100 provides a certified carrier-grade algorithm that has been labeled a benchmark for echo cancellation for OpenVox.
With the improved I/O speed, each card reduces CPU usage and increased card density per server. These cards are fully compatible with Asterisk applications. The open source driver supports an API interface for custom application development.
These cards support industry standard telephony and data protocols, including Primary Rate ISDN (both N. American and Standard Euro) protocol families for voice, PPP, Cisco, HDLC, and Frame Relay data modes. Both line-side and trunk-side interfaces are supported.
