Do Not Disturb
Description
Do Not Disturb blocks incoming calls and Paging announcements. DND permits an extension user to
work by the telephone undisturbed by incoming calls and announcements. The user can activate DND
while their telephone is idle or while on a call. Once activated, incoming trunk calls still flash the line
keys. The user may use the telephone in the normal manner for placing and processing calls.
Five Do Not Disturb options are available at each extension. These options can be accessed via
multiline terminal Softkeys, DND feature key or DND system access code.
1 = Incoming trunk calls blocked.
2 = Paging, incoming Intercom, Call Forwards and transferred trunk calls blocked.
3 = All calls blocked.
4 = Incoming Call Forwards blocked.
0 = Do Not Disturb canceled.
Multiline Line Terminals display the following to indicate the type of DND that is set.
1 = DND EXTERNAL
2 = DND INTERCOM
3 = DND ALL
4 = DND TRANSFER
Conditions
Do Not Disturb access code is programmable via Program 11-11-08.
If there is no Call Forwarding key (Program 15-07: 10~17), the DND key blinks when the
extension is forwarded.
Call Arrival (CAR) Key/ Virtual Extension (VE) do not support DND Programmable Function
keys.
Multiline terminal users can activate or deactivate Do Not Disturb while on a call. This
option is not available for single line telephones.
When DND and Call Forward are set on the same telephone, call forwarding works. If Busy
and No Answer Forwarding are set to different locations, it follows the Busy forwarding.
If an extension already receiving forwarded calls activates DND option 4, callers to the
forwarded extension hear DND tone.
If an extension activates DND option 4, other extensions can still forward calls to it, but the
callers hear DND tone.
An extension user can override Call Forwarding or Do Not Disturb at another extension
using any of the following methods:
1. Program 11-12-01 Service Code Setup (for Service Access)
– Bypass Call
(default: 707)
2. Program 11-16-06 Single Digit Service Code Setup
– DND/Call Forward Override Bypass
