In the echo path, make sure that the echo signal does not cause saturation, waveform distortion, etc., in the external

Make the settings so that the echo return loss (E.R.L.) is attenuating. Further, it is recommended to use the
The E.R.L. is the attenuation (loss) of echo amount from the echo canceller output (Rout) to the echo canceller

When the echo path can change (such as during a reconnected call), it is recommended to carry out a reset using
