2.1.1.6 Intercept Routing
Description
Provides automatic redirection of incoming trunk and intercom calls. There are three types of Intercept Routing as follows:
Feature Description
Intercept Routing—No Answer (IRNA)
If a called party does not answer a call within a preprogrammed time period (IRNA Timer), the call is redirected to the preprogrammed destination.
Intercept Routing—Busy 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 card, the caller hears a ringback tone.
Intercept Routing—DND If a called party is in DND mode, the call is redirected to the preprogrammed destination.
Intercept destinations can be assigned to extension ports.

When the original destination is: The Available Intercept Destination is:
• UM Group The destination assigned to the first extension of the UM group.
• DISA*1 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.

• External Pager (TAFAS)*2
• Other PBX Extension (TIE with no PBX Code)
Not assignable (Intercept Routing is not available.)
*1 Intercept Routing for DISA will redirect a call only if all of the Direct Inward System Access (DISA) ports are busy. Once the call reaches the destination extension by using the DISA feature, the Intercept Routing feature of the extension is used.
*2 By assigning the forward destination of a Virtual PS to a PS Ring Group or external pager, and assigning Intercept Routing destinations to the Virtual PS, calls to these destinations will be redirected to the Intercept Routing destination of the Virtual PS.

Ext. No. of the Virtual PS
When extension 2001 is called from another extension or is the first destination of an incoming trunk call, etc., the call will ring at extension 600 (external pager) first, and then ring at the intercept destination (extension 1001) after the IRNA Timer expires.
Programming Example
Different intercept destinations can be programmed for each time mode (day/lunch/break/night).

Intercept for calls to an outside destination
When an intercom, trunk, or DISA call is received by an extension and forwarded to an outside destination by FWD—All Calls or FWD—Busy, the Intercept Routing feature can be used, if the outside destination is busy or does not answer. For example, when a call is forwarded to a cellular phone by FWD—All Calls, and the cellular phone is busy, the call will be routed to Voice Mail in the PBX.
This feature is also available when a call is forwarded by FWD—No Answer under the following conditions:
– The forwarding destination is in a private network and is busy or does not answer.
– The forwarding destination is in a public network and does not answer.
However, this feature is not available when a call is forwarded by FWD—No Answer to a destination in a public network that is busy.
Conditions
• Intercept Routing—DND on/off
Intercept Routing—DND can be enabled or disabled system programming.
If disabled, one of the following is activated depending on the type of line that a call arrives through:
a. LCOT Card: The incoming trunk call will ring at the original destination while the caller hears a ringback tone.
b. Other Trunk Cards: A busy tone will be sent to the caller.
• If the intercept destination cannot receive the call:
a. Intercept Routing—No Answer: Intercept timer will restart at the original destination, until the call is answered.
b. Intercept Routing—Busy/DND: The call will be sent back to the original destination when the call arrives through the LCOT card. When the call arrives through other trunk cards the caller will hear a busy tone.
• Idle Extension Hunting
If an extension is a member of an idle extension hunting group, calls to that extension will not be redirected by Intercept Routing—Busy/DND. If the extension is busy or in DND mode, calls to that extension will be redirected to the next extension in the idle extension hunting group.
• Intercept Routing for intercom calls can be enabled or disabled on a system basis.
® 18.5 PBX Configuration—CO & Incoming Call—Miscellaneous— Intercept—Intercept Routing for Extension Call
• IRNA Timer
The IRNA timer can be set on a system basis and an extension basis for each time mode (day, lunch, break, night).
® 12.1.1 PBX Configuration—Extension—Wired Extension—Extension Settings—Intercept No Answer Time— Intercept No Answer Time—Day, Lunch, Break, Night
• The Intercept Routing destination for each time mode will not apply for Intercept Routing—Busy. When the original destination is busy, the call is redirected to the Intercept Routing—Busy destination assigned through system programming. If no destination is assigned the caller will hear a busy tone.
• The time modes that are selected for trunk calls arriving at extensions and UM groups are decided on a tenant basis.
• Intercept for calls to an outside destination
– LCOT trunks without reverse circuit detection (® 2.5.4.5 Reverse Circuit) do not support this feature.
– This feature may not be available depending on the specifications of the telephone network.
– This feature is not available when the original call was made from a SIP extension.
