Description
Microphone Disable can be assigned via system programming to any MLX
telephone except a Queued Call Console (QCC) to limit the use of the
speakerphone. When the feature is assigned, the microphone does not
function, but the speaker functions normally. A user can listen to calls or
announcements over the speakerphone but must use the handset to respond.
For some features, such as Auto Dial, Last Number Dial, or Saved Number Dial,
the system automatically selects a line and activates the speakerphone. When
one of these features is used on a telephone with Microphone Disable assigned,
the line is selected and the speaker is activated, but the microphone is muted
automatically; the red LED next to the Mute button goes on. To be heard, the
user lifts the handset and the Mute and Speaker LEDs go off.
Also, when group pages or voice-announced transfers are received on a
telephone with Microphone Disable assigned, the user can hear the
announcement over the speakerphone, but the microphone is muted
automatically. The user must lift the handset to speak to an inside caller who is
transferring a call or calling the user via an SA Voice or ICOM Voice button.
Microphone Disable is appropriate when speakerphones pick up too much
background noise, or are needed only by some employees.
Considerations and Constraints
The LED next to the Mute button goes on whenever the speakerphone is
activated. Pressing the Mute button does not turn off the LED or deactivate
Microphone Disable.
If a user presses the Speaker button before lifting the handset, the system
selects a line and the user can dial a number. The microphone is muted and
the user must lift the handset to speak to the person being called.
