A method of controlling a conference call in a system which comprises a conference bridge for combining several audio signals arriving from terminals and transmitting the combined signal further to at least one of the terminals. The method comprises detecting substantially simultaneously active predetermined audio signals, such as speech signals, in the audio signals of the conference bridge inputs and filtering the audio signals of the inputs with substantially different filters when there is more than one simultaneously active predetermined audio signal. The filtered audio signals are combined into one signal, and the combined signal is transmitted to at least one terminal. <IMAGE>
