Extension Hunting
Description
Extension Hunting routes calls to a predefined group of hunt group member extensions. A call rings in
sequence through the hunt group until answered at a member extension. Extension Hunting is helpful, for
example, for a group of co-workers that share responsibility for answering calls. Each call cycles through the
group until an available member picks it up.
There are three types of Extension Hunting:
❥ Circular Hunting
❥ Terminal Hunting
❥ Uniform Call Distribution (UCD) Hunting
Circular Hunting
A Circular Hunting group consists of a group of extensions programmed into a Circular Hunting list. A call
unanswered at a member extension rings the next extension in the programmed list. If unanswered, the call
will continue to cycle through the hunt group. Depending on the hunt type (see below), Circular Hunting
will occur for transferred outside calls, DILs to a hunt group member, and ringing Intercom calls. Hunting
does not occur for Key Ring and Ring Group calls.
Terminal Hunting
A Terminal Hunting group consists of a group of extensions programmed into a Terminal Hunting list. A call
unanswered at a member extension rings the next extension in the programmed list. The call will cycle
through the group once, until it reaches the last extension in the list. Unlike Circular Hunting, the call will
not cycle back to the top of the hunt list. Depending on the hunt type (see below), Terminal Hunting will
occur for transferred outside calls, DILs to a hunt group member, and ringing Intercom calls. Hunting does
not occur for Key Ring and Ring Group calls.
Uniform Call Distribution (UCD) Hunting
Like Circular and Terminal Hunting, a UCD Hunting also consists of a group of extensions programmed into
a hunt list. The system routes calls into a UCD Group according to the frequency of use of the member
extensions. The first extension rung is the member that has been idle the longest. The last extension rung is
the member that has been idle the shortest.
Each member of the group is additionally associated with a UCD Master Extension Number. To activate
UCD Hunting, an incoming call must route to the UCD Group master number. This is done by placing an
Intercom call to the master number, transferring a call to the master number or setting up a DIL to the master
number. When all members of the UCD Group are busy, the call can route to the programmed UCD Over-
flow destination.
Automatically route calls to co-workers that work closely together.
