You can also set the microphone gain based on the device that you use most frequently. Use any of
the methods:
• Preferred audio device: Set the preferred audio device to what you use most frequently. For
example, if you use analog headset most frequently, then set your preferred device as Headset
from the phone menu Userpreferences> Audio preferences > Preferredaudio device. Then
adjust the microphone gain of the analog headset, listen to the effect. Then save the one you
like. If you use handset most frequently, pick up the handset, ensure you cancel the incoming
call. Then adjust the microphone gain.
• Last used audio device: Set the preferred audio device to None from the phone menu User
