From the Audio Control page, you can adjust the volume level for the audio input and output or mute them. For example, you can mute the audio output during a lecture so that the call participants do not interfere with it and are not recorded.
Procedure
On the web interface navigation menu, go to Control > Audio Control.
To mute the input audio, enable the Input Mute switch.
To mute the output audio, enable the Output Mute switch.
For the Audio Input Digital Gain setting, select the volume level for the audio input.
