2.03 Call Forwarding-No Answer
Description
Call Forwarding-No Answer provides automatic
call transfer to a preset destination if the
extension 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).
If the extension setting this function is in the PITS
programming mode, Call Forwarding-No Answer
is disabled and the caller hears busy tone.
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 appearing on PCO button
• A call routed via DIL 1: N feature
• A call directed to a UCD group
To set Call Forwarding-No Answer, assign
"System-Class of Service", Call Forwarding/Do
Not Disturb to "Yes".
For setting or canceling this function, two
methods are available:
<1> By pressing the FWD/DND button.
<2> By dialing the feature number for
"Call Forwarding-No Answer Set" 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.
An extension user is rejected with reorder tone if he
or she attempts:
• 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.
• To 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 4-I-11.00 "Remote Station Feature Control".
