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.

Mute Alert Tone
You can configure the phone to play an audible tone if the mute status of the phone is changed. This allows you to
know if your phone is in the mute or un-mute state. In addition, you can set a periodic reminder which plays the aud-
ible tone periodically when the phone is in the mute state. The time interval must not be less than 3 seconds.
It is only applicable to CP920 phones.
