Call Handling
One Time Do Not Disturb (One Time DND)
One Time DND allows a Station User to turn off muted ringing that occurs when off-hook
(handset or [SPEAKER]) while on another call. The station user, while off hook, depresses the
DND button which eliminates muted ringing. When the station goes on-hook, the DND button
is extinguished and DND is cancelled.
Operation
To activate One-time DND from a DKTU:

[DND/FOR] button.
The station is in DND; the [DND/FOR] button LED lights.
When the station goes to an idle state, DND is released at the station; the [DND/FOR]
button LED will be extinguished.
