Digium VPMOCT128 Hardware Echo Cancellation Module
Digium's telephony card offerings have the ability to use DSP-based echo cancellation modules. DSP-based echo cancellation can be more successful than software based echo cancellation because it removes the burden of echo cancellation from the PC.
Digium's echo cancellation modules are recommended when handling large call volumes or a high number of channels that would otherwise stress the CPU and result in the potential for poor audio quality.
