Call Forwarding (FWD)/Do Not Disturb (DND) Features-1

Call Forwarding (FWD)
Description

Extensions and incoming call distribution groups can forward their calls to preset destinations. There are
several different types of forwarding, and the circumstances under which the calls are forwarded for each
type differ as follows:

Type Circumstance
All Calls Any time
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 When the extension user's line is busy.
No Answer When the extension user does not answer within a preprogrammed
time.
Busy/No Answer When the extension user's line is busy or the user does not answer
within a preprogrammed time.


Conditions

[General]

• FWD for Trunk Calls/Intercom Calls
The extension user can set the FWD feature for trunk calls, for intercom calls, or for both.
• FWD from Incoming Call Distribution Group (Group FWD)
COS programming determines the incoming call distribution groups that can use this feature.
• FWD to Trunk
COS programming determines the extensions or incoming call distribution groups that can forward calls
externally.
The original extension's TRS/Barring and ARS still apply to the forwarded call.
• Trunk Call Duration
The duration of a trunk call can be restricted by a system timer. Trunk call duration is assigned
separately for calls between an extension user and an outside party, and calls between two outside
parties.
If the timer expires, the line will be disconnected. (. 1.11.8 Trunk Call Limitation)

1.3 Call Forwarding (FWD)/Do Not Disturb (DND) Features
• 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 (when the destination extension is busy), or All Calls
– Idle Extension Hunting—Overflow
– Intercept Routing—Busy/DND (when the destination extension is busy or in DND mode)
– Incoming Call Distribution Group—Overflow

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 incoming call distribution group, and then the call is redirected to the
overflow destination by the Queuing Time Table. (. 1.2.2.4 Queuing Feature)
In the above cases, the forwarding counter resets to zero, and the call can be forwarded up to four times

• Message Waiting
While calls are forwarded, Message Waiting information is not forwarded. The Message button light
turns on at the originally called extension. (. 1.19.1 Message Waiting)
• Idle Extension Hunting
Idle Extension Hunting applies to calls forwarded to a busy extension in an idle extension hunting group.

1.3 Call Forwarding (FWD)/Do Not Disturb (DND) Features
[All Calls and Busy]

• If the forward destination is not available to answer a call, this feature is cancelled and the original
destination will ring for the following type of call:
– Doorphone call
– Trunk calls via the ELCOT, LCOT, or T1 (LCOT/GCOT) cards
[No Answer and Busy/No Answer]

• No Answer Time
The number of rings before the call is forwarded is programmable for each extension.
[Follow Me]

• This feature is only available when the original extension has disabled the "Deny Remote Operation
by Other Extension" setting on a COS basis.
