1.3 Call Forwarding (FWD)/Do Not Disturb (DND) Features

1.3.1 Call Forwarding (FWD)/Do Not Disturb (DND)

1.3.1.1 Call Forwarding (FWD)/Do Not Disturb (DND)–OVERVIEW

Description

When an extension user cannot answer calls (on a call, out of the office, etc.), it is possible to forward or refuse the calls using the following features:
1)Call Forwarding (FWD)
2)Do Not Disturb (DND)
1.FWD
Extensions and incoming call distribution (ICD) groups can forward their incoming calls to preset destinations. (rarrow.gif 1.3.1.2 Call Forwarding (FWD))
2.DND
An extension user can send the tone to let the caller know he or she is not available. (rarrow.gif 1.3.1.3 Do Not Disturb (DND))

Conditions

FWD and DND features apply to:
Intercom calls (including doorphone calls), and CO line calls (including a call from an extension that placed a CO line call on a consultation hold (rarrow.gif 1.12.5 Consultation Hold).)
FWD/DND Button
Both the FWD and DND features for an extension can be customized on a single flexible button.
Only one of these features can be active at a time.
Multiple types of FWD/DND buttons can be customized on an extension.
Group FWD Button
The FWD feature for an ICD group can be customized on a flexible button. Multiple types of Group FWD buttons can be customized on an extension.

Note

Pressing the FWD/DND button (fixed button) in idle status will produce one of the following results, selected through system programming:
When in FWD/DND Setting Mode:
Pressing the button will enter personal programming mode for the FWD/DND setting.
When in FWD/DND Cycle Switch Mode:
Pressing the button will cycle the settings as shown above in [Mode Change].
A FWD/DND button customized on a flexible button is always in FWD/DND Cycle Switch mode, and the mode cannot be changed.
When intercom calls are set to be handled differently from CO line calls (forwarding type, forward destination, DND on/off), we recommend establishing separate buttons for both FWD/DND–Internal and FWD/DND–External, and/or Group FWD–Internal and Group FWD–External, because:
a)the light patterns of the FWD/DND–Both button (including FWD/DND button [fixed button]) and the Group FWD–Both button will indicate the setting for either CO line calls or intercom calls, but not both.
Note
The FWD and DND icons on a PS display reflect the settings for CO line calls only.
b)pressing the FWD/DND–Both button (including FWD/DND button [fixed button]) or the Group FWD–Both button will not change the FWD or DND mode for intercom calls and CO line calls separately.

1.3.1.2 Call Forwarding (FWD)

Description

Extensions and incoming call distribution (ICD) groups can forward their calls to preset destinations. There are four Call Forwarding (FWD) modes, described below.

Mode

Description

All Calls 
All calls are forwarded.
Follow Me:  When an extension user fails to set this feature before leaving the desk, this feature can be set from the destination extension.
Busy 
Calls are forwarded when the extension user's line is busy.
No Answer 
Calls are forwarded when the extension user does not answer within a preprogrammed time (rarrow.gif Call Forwarding–No Answer Time [605]).
Busy/No Answer 
Calls are forwarded when the extension user's line is busy or the user does not answer within a preprogrammed time (rarrow.gif Call Forwarding–No Answer Time [605]).
Depending on the type of incoming call (intercom or CO line call), it is possible to set different destination for each.

*
If an extension user cannot call certain extensions on a COS basis (rarrow.gif 1.1.2.2 Internal Call Block), the extension user cannot forward his or her calls to those extensions either.

Conditions

[General]
FWD for CO Line Calls/Intercom Calls
The FWD feature can be set for CO line calls, for intercom calls, or for both of them by the extension user.
FWD from ICD Group (Group FWD)
COS programming determines the ICD groups that can use this feature.
FWD to CO Line
COS programming determines the extensions or ICD groups that can forward calls to an outside party (rarrow.gif Call Forwarding to CO Line [504]).
The original extension's Toll Restriction (TRS) and Automatic Route Selection (ARS) still apply to the forwarded call. (rarrow.gif 1.8.1 Toll Restriction (TRS), rarrow.gif 1.9.1 Automatic Route Selection (ARS))
CO Line Call Duration
If a call between an extension user and an outside party, or between two outside parties is established, the call duration can be restricted by a system timer (rarrow.gif Extension-to-CO Line Call Duration [472], rarrow.gif CO-to-CO Line Call Duration [473]). If the timer expires, the line will be disconnected. (rarrow.gif 1.10.8 CO Line Call Limitation)
Multiple FWD
Calls can be forwarded up to four times. The following forwarding features are counted as Multiple FWD:
FWD–Busy or Busy/No Answer (in case a destination extension is busy), or All Calls
Idle Extension Hunting–Overflow
Intercept Routing–Busy/DND (in case a destination extension is busy or in DND mode)
ICD Group Overflow
imf1111a.gif
In the above illustration, forwarding stops at extension E. However, forwarding can go farther in the following cases:
If a destination extension rings, and then the call is redirected to the forward destination by the FWD–No Answer or Busy/No Answer feature.
If a destination extension rings, and then the call is redirected to the intercept destination by the Intercept Routing–No Answer feature.
If a call waits in a queue of an ICD group, and then the call is redirected to the overflow destination by the Queuing Time Table. (rarrow.gif 1.2.2.3 Queuing Feature)
In the above cases, the forwarding counters reset to zero, and calls can be forwarded up to four times again from the applicable extension that occurred in the case above.
imf1112a.gif
Boss & Secretary feature
It is possible to call the original extension from the destination extension regardless of the forward setting.
imf1115a.gif
Message Waiting
When a call is forwarded, Message Waiting information is not forwarded. The MESSAGE button light turns on at the originally called extension. (rarrow.gif 1.17.1 Message Waiting)
Idle Extension Hunting
Idle Extension Hunting applies to calls forwarded to a busy extension in an idle extension hunting group.

[All Calls and Busy]
If the forward destination is not available to answer a call, this feature is canceled and the original destination will ring for the following types of calls:
Doorphone call
CO Line calls which arrived through an LCOT or T1 (LCOT/GCOT) card

[No Answer and Busy/No Answer]
No Answer Time
The number of rings before the call is forwarded is programmable for each extension (rarrow.gif Call Forwarding–No Answer Time [605]).

[Follow Me]
This feature is only available when "Deny Remote Operation by Other Extension" is disabled for the original extension's COS.

1.3.1.3 Do Not Disturb (DND)

Description

An extension user can make use of the Do Not Disturb (DND) feature. If this feature is set, calls will not arrive at the extension, but arrive at other extension by using the Idle Extension Hunting feature (rarrow.gif 1.2.1 Idle Extension Hunting) or the Intercept Routing–Busy/DND feature (rarrow.gif 1.1.1.5 Intercept Routing). When a destination cannot be found, the calling extension will hear the DND tone, while the calling outside party will hear a busy tone.

Conditions

DND for CO Line Calls/Intercom Calls
The DND feature can be set for CO line calls, for intercom calls, or for both of them by the extension user.
DSS button in DND Mode
The DSS button light will turn red if the assigned extension has set DND.
DND Override
An extension in DND mode can be called by other extension users who are allowed to override DND based on their Class of Service (COS) (rarrow.gif DND Override [507]).
Paging DND
It is programmable whether the PBX pages extensions in DND mode through system programming. (rarrow.gif 1.14.1 Paging)
Intercept Routing–Busy/DND
If a call arrives at an extension which is in DND mode, the call can be redirected to the preprogrammed destination via the Intercept Routing–Busy/DND feature.
Idle Extension Hunting
While searching for an idle extension within an idle extension hunting group, any extension which has DND set will be skipped. The call will go to the next extension in the group, not to the Intercept Routing–Busy/DND destination.
If a CO line call arrives through an LCOT or T1 (LCOT/GCOT) card and is directed to an extension which is in DND mode, and if the Intercept Routing–Busy/DND destination is not available and furthermore there is no available extension in the extension's idle extension hunting group, the original destination will ring even though it is in DND mode.
Calls from a doorphone arrive at an extension even when the extension is in DND mode.
