1.3 Call Forwarding (FWD)/Do Not Disturb (DND) Features
44 Feature Guide
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
(→ Call Forwarding to CO Line [504]).
The original extension's Toll Restriction (TRS) and Automatic Route Selection (ARS) still apply to the
forwarded call. (→ 1.8.1 Toll Restriction (TRS), → 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 (→ Extension-to-CO Line Call Duration [472], →
CO-to-CO Line Call Duration [473]). If the timer expires, the line will be disconnected. (→ 1.10.7 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
In the above illustration, forwarding stops at extension E. However, forwarding can go farther in the
following cases:
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.
– 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. (→ 1.2.2.3 Queuing Feature)
