1.1.1.6 Intercept Routing
Description
Provides automatic redirection of incoming trunk and intercom calls. There are three types of Intercept Routing
as follows:
Feature
Intercept Routing—No Answer
(IRNA)
Intercept Routing—Busy
Intercept Routing—DND
Intercept destinations can be assigned to extension ports.
® [604] Extension Intercept Destination
When the original destination is:
•
Wired Extension (PT/SLT/T1-OPX)
•
PS
•
ICD Group
•
VM Group (DTMF/DPT)
•
DISA
*1
If a called party does not answer a call within a preprogrammed time
period (IRNA Timer), the call is redirected to the preprogrammed
destination.
If a called party is already handling a call, new calls are handled as
follows:
–
The call is redirected to the preprogrammed Intercept Routing—
Busy destination.
–
If an Intercept Routing—Busy destination is not enabled, the
caller will hear a busy tone. However, if the call is made through
an LCOT/CLCOT or T1 [LCOT/GCOT] card, the caller hears a
ringback tone.
If a called party is in DND mode, the call is redirected to the
preprogrammed destination.
The Available Intercept Destination is:
The destination assigned to the original extension.
® [604] Extension Intercept Destination
The ICD Group Overflow destination assigned to the
group. (® 1.2.2.6 Overflow Feature)
® [625] Destination for Overflow Time Expiration
The destination assigned to the first extension of the
VM group.
If all DISA ports are busy when a call is made using
DISA, one of the following can be selected through
system programming:
•
Disable: Busy tone is sent to the caller. When
using an analogue trunk, a ringback tone is sent.
•
Operator: The call will be redirected to the
operator.
•
AA-0, AA-9: The call will be redirected to the
destination assigned to that AA number.
