Automatic microphone selection
The softphone selects the microphone automatically.
Select this option if, for example, you are using a portable device for a conference call and would like to connect a USB headset during this time, to continue the conference call.
Echo cancellation
The echo that the other calling party might hear is reduced or removed.
We recommend you always leave this function activated unless you are using a desk telephone with integrated echo cancellation.
Note: It is technically impossible to cancel the echo coming from the other end. If you hear an echo when using the softphone, the other calling party must enable echo cancellation, if necessary.Automatic gain control
Automatically regulates the microphone level, to ensure your voice is always at the correct volume, no matter which microphone you use or how far you are from the microphone.
We recommend you always leave this function activated.
Noise suppression
Removes disruptive background noise during the phone call.
