Operational IP Phone Features Do Not Disturb (DND)
The IP phones have a feature you can enable called "Do not Disturb (DND). You
can configure DND on softkeys and programmable keys using the Aastra Web UI
or the configuration files.
If DND is configured on the phone, the softkey or programmable key switches
DND ON and OFF. If the phone shares a line with other phones, only the phone
that has DND configured is affected.
The second line on the screen of the IP phone shows when DND is configured.
When a call comes in on the line, the caller hears a busy signal or recorded
message, depending on the server configuration.
Configuring DND
Use the following procedures to configure DND on the IP phone..
