Description
Do Not Disturb prevents calls from ringing and prevents paging over a user’s
speakerphone. When the feature is turned on and the user receives an outside
call, the caller hears ringback, but the user’s telephone does not ring. The
green LED next to the line button with the ringing call flashes to indicate an
incoming call, and, if the user chooses, the call can be answered. If the feature
is turned on and the user receives an inside call, the inside caller hears a busy
signal. The user’s telephone does not ring, and the green LED next to an SA or
ICOM button does not flash.
The following types of priority calls override Do Not Disturb and cause the user’s
telephone to ring (the green LED also flashes):
■ a call (including a transferred call) from any Coverage receiver to a
sender with Do Not Disturb on
■ a Barge-In call
■ a returning transferred or camped-on call, or a parked call returning to a
Direct-Line Console (DLC) operator
■ a Callback call, notifying the user that a call to a busy extension or to a
busy pool (Hybrid/PBX mode only) can be completed
■ a Reminder Service call
In a Release 2.0 (or later) system, when the user turns on the feature, the
system automatically posts the message DO Not Disturb. This message
appears on the Home screen of an MLX display telephone user with Do Not
Disturb turned on, and on the screen of any inside caller with a display
telephone who calls that user. When the user turns off Do Not Disturb, the
system automatically unposts the message. The user can also post and unpost
the message by using a programmed Posted Message button. However,
using this button only posts or unposts the message; it does not turn on or turn
off the Do Not Disturb feature.
