Patent ID: 7142535

Claim:
A circuit for processing data representative of voice signals, the circuit having two signal paths comprising: in a first signal path, a queue for storing first voice data representative of a first voice signal; and a digital to analog converter having an output, the digital to analog converter for receiving the first voice data from the queue, the digital to analog converter converting the first voice data to a first analog representation of the first voice signal, and, in a second signal path, an analog to digital converter having an input, the analog to digital converter for converting a second analog representation of a second voice signal to second voice data; and signal processing circuitry for removing from the second voice signal represented by the second voice data, a portion of the first voice signal representative of the first voice data, and wherein the circuit further comprises at least one processor that enables processing of received voice packets into the first voice data and processing of the second voice data into transmit voice packets; and wherein the at least one processor enables adjusting the operation of the queue according to a rate of packet arrival.
