Call Mute

You can mute the microphone of the active audio device (handset, headset or speakerphone) on Yealink phones
during an active call or when the phone is on the pre-dialing/dialing/calling/ringing screen. The call is automatically
muted when setting up successfully. Muting before a call is answered prevents the other party from hearing the
local discussion.
You can activate the mute feature by pressing the MUTE key. Normally, the mute feature is automatically deac-
tivated when the active call ends. You can use keep mute feature to keep the mute state persisting across the calls.
Note: Muting microphone on the pre-dialing/dialing/calling/ringing screen is not available on T23P/T23G/T21(P) E2
phones when the keep mute feature is disabled.

Keep Mute
Keep mute, also known as persistent mute, allows you to keep the mute state persisting across calls.
In a call center or meet room, if incoming calls are answered automatically, the callers may hear the local dis-
cussion. Therefore, you can mute the phone in an idle state to prevent the unintended situation. The mute state per-
sists across calls until you unmute the microphone manually or until the phone restarts.
You can activate the mute feature by pressing the MUTE key in idle/pre-dialing/dialing/ringing/calling/talking state.
Note : For T23P/T23G/T21(P) E2 phones, the Cancel key (X key) can be used to cancel actions, reject incoming calls,
mute/un-mutes calls or activate the mute feature. If keep mute feature is enabled, the Cancel key can only be used as a mute
key.
