If an extension user is not permitted by COS to call a certain extension
(
® 2.1.2.2 Internal Call Block), the FWD feature will not
function if that extension is set as the forwarding destination.
Parallel Ringing When Forwarding to Trunk
When an unanswered call is forwarded to an outside line, such as a cellular phone, the forwarding
extension’s phone will continue ringing until the forwarded call is answered at either phone. This feature can
be enabled for each extension through system programming. Even when the outside destination answers the
call, DSS buttons for the forwarding extension are displayed as busy. The Intercept Routing feature is available
for when parallel ringing is not answered.
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
