  • Method and device for handling echo in a communication network
    Patent number: 7099459
    Abstract: A method is provided for use with a telecommunication relay device adapted to convey voice-band data signals over a given transmission path in a telecommunication network, which relay comprises a transmitter operative to encode and transmit voice-band data information, and a receiver operative to receive and decode said information and regenerate a voice-band data signal therefrom. The method that is provided comprises handling an echo associated with the regenerated signal and returned from the telecommunication network, in order to prevent it from being relayed backwards, thus impairing the voice-band data call process. The method comprises detecting and identifying the returned echo as such, and preventing it from being relayed.
