Adjust the Microphone Gain
You can adjust the microphone gain for the handset, handsfree, and the analog headsets, but
not the headsets that use 3.5-mm jack or the USB ports. You make the gain louder or softer to
get a good input level.
You can change the microphone gain while you are on a call. If you save the settings during the
call, the change is immediate and is used on subsequent calls. If you don't save the settings
during the call, the change is only used for the current call.

You can also set the microphone gain based on the device that you use most frequently. Use
either method:

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 User preferences >
Audio preferences > Preferred audio 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 preferences > Audio preferences > Preferred audio device.
Then toggle the audio path once. For example, press the microphone of the

microphone of the handsfree will be used for the gain adjustment.
