Abstract
A voice packet dynamic echo cancellation system includes an input/output unit configured to communicate over a packet network and a storage unit configured to store network performance information associated with node segments on the packet network. The system also includes a processing unit configured to execute instructions to: set-up a call from an originating call device to a terminating call device; determine the network performance of the call between the originating call device and the terminating call device; locate an echo signal of the call to the originating call device based on the network performance; produce a echo cancellation signal based on the echo signal; cancel the echo signal with the echo cancellation signal; and recheck the network performance information during a duration of the call and adjust the specific delay point of the received signal window based on the network performance information.
