<p>An input signal from the input source is received. An attenuation of an echo canceller filter is calculated using at least the input signal. A spectral component of a frequency band of an echo suppressor is adjusted to perform enhanced suppression using the calculated attenuation. A comfort noise factor is calculated using at least the input signal and the calculated attenuation. The comfort noise to the output of the echo suppressor is adjusted to obtain a modified input signal.</p>
