Call Features
37
The phone screen displays the redial times and interval. The phone will retry as many times as configured until the
callee answers the call.
Muting/Unmuting Audio
When you are in a call, you can mute the audio, so that you can hear the other person, but they cannot hear you.
Procedure
1. Press the MUTE key during a call.
The mute key LED glows red on all phones except the T40P/T40G phones.
2. Press the MUTE key again to unmute the call.
The mute key LED goes out on all phones except the T40P/T40G phones.
Tip
You can also mute the microphone while the phone is dialing or ringing so that the other party cannot hear you when the
call is set up.
Keep Mute
In a meeting room, if incoming calls are answered automatically on your phone, callers may hear your discussion with
your colleagues. You can keep the phone in mute to prevent this unintended situation.
The mute state of your phone persists across calls. The phone stays in the mute state until you unmute the microphone
manually or until the phone restarts.
Before You Begin
Check with your system administrator if keep mute is configured on your phone.
