Features
Considerations and Constraints
Do Not Disturb must be programmed onto an available button.
If a user turns on Do Not Disturb while receiving a call (either ringing or voice
announced), the caller continues to hear ringback (or voice announce), but the
user who turned on Do Not Disturb does not hear ringing. The Do Not Disturb
feature remains on.
When the principal’s Do Not Disturb is turned on, a user’s calls ring at other
telephones with shared Personal Lines or at Coverage receivers, but not at
other telephones with Shared SA buttons.
Telephone Differences
Direct-Line Consoles
The green LED next to an Auto Dial or DSS button on a DLC goes on when a
user turns on Do Not Disturb, indicating that the user is not available.
Queued Call Consoles
Do Not Disturb cannot be used on a Queued Call Console (QCC); Position Busy
must be used instead. The green LED next to a DSS button goes on when a
user turns on Do Not Disturb, indicating that the user is not available.
Other Multiline Telephones
Multiline telephone users turn on Do Not Disturb by pressing the programmed
Do Not Disturb button. The green LED next to the button goes on to indicate
the feature is active. To turn off the feature, the user presses the programmed
Do Not Disturb button again. The green LED next to the button goes off to
indicate the feature is turned off. Feature codes cannot be used to turn on and
off Do Not Disturb. An MLX telephone user can select the feature from the
display only while programming a Do Not Disturb button.
In a Release 2.0 (or later) system, turning on Do Not Disturb on an analog
multiline or MLX-10 non-display telephone does not automatically post the Do
Not Disturb message; the user must program a Posted Message button for
the message to be posted automatically. In this case, when Do Not Disturb is
turned on, the green LED next to the Posted Message button is lit automatically
and the Do Not Disturb message is posted. When Do Not Disturb is turned
off, the system automatically turns off the green LED next to the Posted
Message button.
