Feature Guide 71
[Available Destinations]
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)
