Call Forwarding-Busy/Off-Hook provides
automatic call transfer to a preset destination
when the user's extension is busy or off-hook.
Incoming calls can be forwarded to extension
users, Voice Mail ports, or operators.
"FDN for General Operator Call" is used to assign
operators as the destination of Call Forwarding.
Refer to Section 10-D-1.01 "Operation (1/3)" for
further information.

Forwarding treatment.

Conditions
An extension user may have only one type of
Call Forwarding/Do Not Disturb feature in effect
at any time. If a second type is assigned, the
previously assigned type is canceled.
If the extension to which calls are to be
forwarded itself is in a call forward mode, a call is
not forwarded furthermore. The call rings at the
first forwarded extension. In case of an outside
call, if not answered in a specified time period,
the call will be routed to another destination, if
available, based on the "Intercept Routing-No
Answer" feature.
Calls from any VM extension will not be
forwarded, if forwarding destination is another
VM extension.
The following attempt will be rejected with
reorder tone.
• In case of the parameter "Tenant Service" is
employed, the user cannot set the destination
to an extension or an Attendant Console which
belongs to another tenant.
• The extension user cannot call another
extension that presets its destination to the
user's extension.
The Operators (Attendant Console or Extension)
can cancel the Call Forwarding/Do Not Disturb
feature assigned to the extension users. Refer to
Section 6-J-5.00 "Remote Station Feature
Control".
