Call Mute
You can mute the microphone of the active audio device during an active call so that the other
party cannot hear you. You can also mute the microphone while dialing so that the other party
cannot hear you when the call is set up. It helps prevent the other party from hearing the
informal discussion when auto answer is enabled on his/her phone.
Normally, the mute state ends when the active call ends. Keep mute feature enables you to
make the mute state of the phone persist across calls and to mute the phone’s microphone on
any screen (e.g., idle screen). It helps prevent the other party from hearing the noise coming
from your room when auto answer is enabled on your phone.
Call mute applies to all modes (Handset, Headset and Speakerphone).
