Conditions
•If the intercept destination is busy or in DND mode and therefore cannot receive the call:
a. When the call was intercepted via Intercept Routing—No Answer, the call is sent back to the original
destination and continues to ring at the original destination until answered.
b. When the call was intercepted via Intercept Routing—Busy and arrived through an ELCOT/LCOT or
T1 (LCOT/GCOT) card, the call waits at the original destination. If the extension has Call Waiting
activated, the user will hear a call waiting tone. When the call arrived on any other card, the caller hears
a busy tone.
c. When the call was intercepted via Intercept Routing—DND and arrived through an ELCOT/LCOT or
T1 (LCOT/GCOT) card, the call waits at the original destination and it rings. When the call arrived
through any other card, the caller hears a busy tone.
•If the intercept destination can, but does not, answer the call:
The call continues to ring at the intercept destination until answered.
•Intercept Routing—DND on/off
Intercept Routing—DND can each be enabled or disabled for the entire system, through system
programming. If enabled, calls will be routed to the appropriate destination.
If disabled, a call to an extension which is in DND mode will be handled as described below, depending
on the type of line carrying the call.
12.6 [10-4] Miscellaneous— Intercept—Intercept Routing - DND (Destination sets DND.)
a. ELCOT/LCOT or T1 (LCOT/GCOT) Card: The caller will hear a ringback tone. If in DND mode, the
extension will ring.
b. All other lines: An outside caller will hear a busy tone and an extension caller will hear a DND 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.
12.6 [10-4] 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).
6.1 [4-1-1] 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 CO line calls arriving at extensions and VM groups are decided on
a tenant basis.
•KX-TDA50/KX-TDA100/KX-TDA200 only
When an intercom, CO line, or DISA call is received by an extension and forwarded (e.g., FWD—All Calls)
to an outside destination, and the outside destination is busy or does not answer, the Intercept Routing
feature can be used. This can be useful when calls are forwarded to cellular phones.
This feature may not be available depending on the specifications of some CO lines.
