1.2 Receiving Group Features
1.2.1 Idle Extension Hunting
Description
If a called extension is busy, Idle Extension Hunting redirects the call to an idle member of the same 
extension group, if that group has been assigned as an idle extension hunting group through system 
programming ( Hunting Group Set [100]). Idle extensions are automatically searched for according to a 
preprogrammed hunting type ( Hunting Type [101]).
This feature is also known as Station Hunting.
Conditions
• Idle Extension Hunting applies to:
Intercom calls and outside (CO) line calls directed to a single extension.
• An extension can belong to only one extension group ( Extension Group [600]). One hunting type 
can be programmed for each extension group.
• If all the searched extensions are busy, a busy tone will be heard.
• A user can leave an idle extension hunting group temporarily by logging out of the group, and rejoin the 
group by logging back in (
1.2.4 Log-in/Log-out).
• FWD/DND Mode
When searching for an idle extension within an idle extension hunting group, any extension that has set 
FWD, DND, or Log-out will be skipped ( 1.3.1 Call Forwarding (FWD)/Do Not Disturb (DND)). 
However, if the extension that receives the call first has set FWD or DND, Idle Extension Hunting will 
not function and the call will be forwarded to the preprogrammed destination (when FWD is set) or will 
not be received at all (when DND is set).
Type Description
Circular Hunting An idle extension is searched for in a circular fashion one time according 
to the numerical order of the jacks.
Terminated Hunting An idle extension is searched for in the numerical order of the jacks, until 
reaching the extension that is connected to the highest-numbered jack in 
the group.
