System Forwarding
System forwarding is a standard feature that provides the ability to program the system so that
calls ringing at an endpoint will follow a database-programmed “forwarding path” that routes
the call based on the type of call and the status of the intended endpoint. (The Call Forwarding
endpoint feature can be used to override System Forwarding.) Several terms will be used to
describe this feature, including:
• Principal Station: Original endpoint being called.
• Forwarding Point: A destination (endpoint, hunt group, or off-node device) to which
the system-forwarded call is directed. Each forwarding path can contain up to four for-
warding points.
• Forwarding Path: The sequence of forwarding points to which the call will be sent.
Forwarding paths are programmed in the database. Up to 200 unique paths can be pro-
grammed. Each endpoint can have up to three forwarding paths.
Two system timers are used with this feature:
• System Forwarding Initiate: This timer determines how long a call will ring (unan-
swered) at the principal station before moving to the first forwarding point. The default
value is 15 seconds, and the range is 2-255 seconds.
• System Forwarding Advance: This timer determines how long the call will ring
(unanswered) before moving to the next forwarding point. The default value is 15 sec-
onds, and the range is 2-255 seconds.
For each forwarding path assigned to the endpoint, the system checks the following three crite-
ria to determine if and when a call should be forwarded:
• Type of incoming call: The following six different types of calls can be programmed to
be sent to the forwarding path:
— Outside calls received through a call routing table (including DID and E&M calls,
but not including DISA calls)
— Ringing outside calls
— Transferred outside calls (including Automated Attendant and Voice Mail trans-
fers)
— Recalling outside calls
— DISA calls (including DISA calls received through a call routing table)
— Intercom calls
• Endpoint status: The system recognizes four different types of endpoint status.
— No Answer: If the call is not answered at the principal station before the System
Forwarding Initiate timer expires, the system sends the call to the forwarding path.
— Busy: If the principal station is busy, the system immediately sends the call to the
forwarding path. Both “No Answer” and “Busy” can be selected together to form
a “Not Available” status.
— Do-Not-Disturb: If the principal station is in Do-Not-Disturb, the system immedi-
ately sends the call to the forwarding path.
— Immediate: The system immediately sends the call to the forwarding path. The
principal station user cannot answer an immediately forwarded call, but can
reverse transfer it from the forwarding point.
• Day-mode/night-mode status: The system day/night mode is used to determine if a
forwarding path is taken. Either day mode, night mode, or both may be specified.
For an example, refer to the diagram below. In the example, the principal station user wants
direct ring-in or transferred calls to ring at his or her endpoint during day mode. The principal
station has a forwarding path with two forwarding points: a hunt group and Voice Mail. If the
