2.04 Call Forwarding-Busy/Off-Hook/No
Answer
Description
Call Forwarding-Busy/Off-Hook/No Answer
provides automatic call transfer to a preset
destination if the user's extension is busy off-hook
or the user cannot answer the call in a determined
period (that is, if the caller is not answered while
hearing ringback tone in a specified period).
Determine the duration from the arrival of a call to
the start of Call Forwarding (period of no answer)
by "System-System Timer", Call Forwarding-No
Answer Time-Out.
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.
The following incoming calls do not receive Call
Forwarding treatment.
• A call from doorphone
• A call routed via DIL 1: N feature
• A call directed to a UCD group
To set Call Forwarding-Busy/Off-Hook/No Answer,
assign "System-Class of Service", Call Forwarding
/Do Not Disturb" to "Yes".
To set and cancel this function, dial the feature
number for "Call Forwarding-Busy/No Answer" and
"Call Forwarding/Do Not Disturb Cancel".

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".
