Controlling echo cancellation includes receiving signals associated with a call. A signal of the signals is detected. Whether the detected signal is a high speed signal or a low speed signal is determined. Echo cancellation is disabled if the detected signal is a high speed signal. The echo cancellation is enabled if the detected signal is a low speed signal.

La commande de suppression d'échos passe par la réception de signaux associés à un appel. Un signal est détecté parmi des signaux. On détermine si ce signal est un signal grande vitesse ou basse vitesse. La suppression d'écho n'intervient pas si le signal détecté est un signal grande vitesse, mais intervient en revanche si ce même signal est un signal basse vitesse.
