Features
Headset/Handset Mute
Headset/Handset Mute allows an MLX telephone user or operator to turn the
microphone in the headset or handset off and on. The user or operator can
then talk privately with another person in the same room without the caller
hearing the conversation. If headset operation is on, Headset/Handset Mute
turns off the headset microphone; if headset operation is off, Headset/Handset
Mute turns off the handset microphone. The red LED next to the
Headset/Handset Mute button is on when the headset or handset microphone
is off; it is off when the headset or handset microphone is on.
When headset operation is off, the handset microphone can be turned off using
Headset/Handset Mute only when the user lifts the handset.
When headset operation is on, the user should press the programmed Headset
Hang Up button to end an outside call even if the caller hangs up.
For an MLX telephone user or MLX DLC operator to use Headset/Handset mute,
a Headset/Handset Mute button must be programmed on the telephone or
console, either through extension programming or through centralized
telephone programming.
A Headset/Handset Mute button is a fixed feature on a QCC and cannot be
deleted or changed.
Considerations and Constraints
The headset, handset, and speakerphone can be used only one at a time.
Headset Hang Up cannot be programmed on a QCC.
Headset Options cannot be used on analog multiline telephones or on single-
line telephones.
A headset user must manually select a line button or Call button (on the QCC)
before making an inside or outside call.
A user can press the Speaker button to move the call from the headset to the
speakerphone.
When two or more users answer the same call on a Shared SA or Personal Line
button, the red and green LEDs next to the button go on, but only one person
has a talk path with the caller. The use of Privacy is recommended to eliminate
competition for the same call.
