SBX IP 320 Features & Operation Guide
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:
While in an off-hook state or connecting a CO line or intercom call, press the
[DND/FWD] button.
The station is in DND; the [DND/FWD] button LED lights.
When the station goes to an idle state, DND is released at the station; the [DND/FWD]
button LED will be extinguished.
Admin Programming
• Do-Not-Disturb (PGM 111 - FLEX 3)
Do Not Disturb (DND) with Pre-Selected Message
A station can be programmed with a pre-selected message option of [P-MSG DND] Admin -
ringing or activating as DND.
If [P-MSG DND] Admin is ON for a station, then CO and ICM ring is treated just like the DND
feature:
• A pre-selected message will be shown to a calling station with a busy tone for an ICM
call.
• A busy tone with a busy message will be provided to a caller of an external DID user.
• For DISA CO, an external user will hear a "Do not disturb" voice message and they can
retry again later.
