5.00 Intercept Routing-No
Answer (IRNA)
Description
If an incoming outside call directed to a single
extension is not answered in a specified time
period, it can be redirected to another destination
in the system.
Another destination can be:
• An Attendant Console
• An extension user
• A Voice Mail extension
For further information about IRNA and a Voice
Mail extension, refer to Section 3-F-10.00 "Voice
Processing System (VPS)".
This feature also applies to the following calls.
• When an incoming outside call rings back at the
extension who once put the call on hold, is not
answered in a specified time period. (Held
Reminder Call)
• When an incoming outside call rings back at the
extension who once transferred the call to
another extension, is not answered in a
specified time period. (Transfer Recall)
The destination of Intercept Routing during day
and night are assigned in "Group-Trunk Group",
Intercept Routing (Day) and Intercept Routing
(Night) on a trunk group basis.
Set the duration to start Intercept Routing in
"System-System Timer", Intercept Routing Time-
Out (System).
The duration to start Intercept Routing for DISA
calls follows the setting in "System-System Timer",
Intercept Routing Time-Out (DISA).
For details about DISA, refer to Section 3-D-2.02
"Direct Inward System Access (DISA)".

Conditions
Intercept Routing-No Answer works for the
following incoming CO calls.
1. All incoming CO calls other than calls
placed on DIL1 : N, Private CO, Attendant
Consoles, Remote and UCD
2. Transfer Recall calls (except those to
Attendant Consoles)
3. Held Call Reminder calls (except those to
Attendant Consoles, calls on Exclusive
Hold, calls on hold on Private CO lines)
4. An incoming outside call via DISA/DID
which comes in on an extension in the DND
mode.
Call Forwarding or Do Not Disturb feature
assigned on the IRNA destination does not work
on the call which has been transferred to it by the
IRNA feature.
If the IRNA destination is not currently available to
answer the call transferred by the IRNA feature,
the call may receive the treatment of the Station
Hunting feature.
If the destination extension of a direct incoming
outside call is in the data line security mode,
IRNA feature does not work on it.
Refer to Section 4-I-6.00 "Data Line Security" for
further information.
If the destination is a PITS with display, it shows:
