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.
Call mute applies to all modes (Handset, Headset and Speakerphone).
Keep Mute
Normally, the mute feature is deactivated when the active call ends. Keep mute feature enables
you to make the mute state of your phone persist across calls. This feature should be
pre-configured by your system administrator. When keep mute is enabled and you press the
MUTE key, the phone stays in the mute state until you un-mute the microphone or until the
phone restarts. It helps prevent the other party from hearing the noise coming from your room
when auto answer is enabled on your phone. When you mute the phone in an idle state or any
other states, the mute key LED illuminates solid red and the icon appears on the status bar.
