The Admission Gain Control option is used to equalize the voice levels of all participants in the conference. In case if some participants have too low voice level while others sound too loud, this option is used to adjust all voices to some average level before sending them to the conference.
The AGC Settings page is used to enable and configure the Admission Gain Control parameters.
The Enable AGC checkbox is used to enable the Admission Gain Control option on the corresponding conference.
The Low Threshold and High Threshold fields indicate the range of the acceptable voice level in the conference to which any low or high voices out of this range should be adjusted. The fields may have values in a range between -50 and 0 dB.
