Introduction
Echo is most common when you are utilizing a VoIP system because a VoIP system often introduces laterncy, which analog systems do not have, and frequency attempts conversion between a 2-wire and 4-wire system. Even thoguh echo may be present, you never have to experience it when making a call. 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.
