pressing the MUTE key. Normally, mute feature is automatically deactivated when the active
call ends. You can enable keep mute feature to keep the mute state persist across the calls.

Mute during the call
You can mute the microphone of the active audio device during an active call, and then the
other party cannot hear you.
Mute while dialing/ringing
You can mute the microphone of the active audio device when the phone is on the pre-
