Extension of Another PBX (via TIE Line, Access

ü–
*1 If an extension user is not permitted by COS to call a certain extension (® 9.1.14 Internal Call Block), the FWD feature will not
function if that extension is set as the forwarding destination.
Conditions
[General]
•FWD for CO Line Calls/Intercom Calls
The extension user can set the FWD feature for CO line 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 CO Line
COS programming determines the extensions or incoming call distribution groups that can forward calls
externally.
The original extension’s Toll Restriction and ARS still apply to the forwarded call.
•CO Line Call Duration
The duration of a CO line call can be restricted by a system timer. CO line 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. (® 3.1.15 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 (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

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 incoming call distribution group, and then the call is redirected to the
overflow destination by the Queuing Time Table. (® 9.1.6 ICD Group Features—Queuing)
