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.
