Abstract: Disclosed are a method and an apparatus for processing communication signals in a telephony or communication system. In various embodiments, the method or the apparatus comprises identifying a first signal which comprises an incoming communication signal and a feedback signal, controlling a logic for cancelling or suppressing a feedback effect based at least in part upon the first signal, processing the first signal using an adaptive filter based at least in part upon the first signal and a result of controlling the logic for cancelling or suppressing the feedback effect, and causing the processed first signal to be transmitted to a first output device. In some embodiments, the method and the apparatus further comprise identifying a communication context which the communication system is currently in. In some embodiments, the method and apparatus further comprise determining a filter coefficient for the adaptive filter.
