Conditions
[General]
•FWD for Trunk Calls/Intercom Calls
The FWD feature can be set for trunk calls, for intercom calls, or for both of them by the extension user.
•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 ( 
Call Forwarding to Trunk [504]).
The original extension’s TRS/Barring and ARS still apply to the forwarded call.
