Hunt Groups
Pre CPC-EX Processor
The DBS provides sixteen hunt groups. each group can have a maximum of eight member extensions. An
extension can only belong to one hunt group, however it is possible to forward calls to a further hunt group if all
members of the first group are busy. There are two type of hunt group, Terminate and Circular. The settings and
members for each group are set during system installation, changes must be referred to a suitably qualified
engineer.
Terminate Hunt Groups will only operate when calls are made to the first extension in the member list - the master
extension. If the master extension is busy the system will search for the first idle extension and route the call to it.
Calls to extensions other than the master extension will not hunt.
Circular Hunt Groups will always hunt. A call to any member extension which is busy will search the member list
sequentially until a free extension is found and the call can be routed.
If an extension in a hunt group sets DND , call forward or absence message it is not handled as a member of a
hunt group until the feature is cancelled.
With CPC-EX Processor
The hunt group facilities have been extended. The DBS will now support up to 24 hunt groups of up to 32 member
extensions. Cyclic hunting and No Answer hunting ( ringing hunting ) are now available for internal call directed at
hunt groups according to programming. Circular and terminate options are unchanged from earlier processor
versions.
Cyclic Hunting
The first call will hunt from member 1 upwards until a free extension is located and ring there. The next call will
begin to hunt from the member extension following the last one which received a cyclic hunt call, until a free
extension is located, and so on for successive calls to the group. When the last member is reached hunting
continues from member 1 and the cycle repeats. This will give an even call distribution across the members of the
hunt group.
To operate Cyclic Hunting the hunt group type must be set to ‘cyclic’ and the first extension assigned to a virtual
extension number ( i.e. An extension which is not installed or covered by spare extension card capacity) or a
permanently busy extension and all calls directed to this first member extension.
No Answer Hunting
An internal call will ring on a member extension, and if unanswered will move onto the next extension and
continue to do this until answered or transferred to a non No Answer Hunting group.
No Answer hunting uses 2 new timers; a member no answer timer and a group no answer timer. This mode of
hunting can be used with terminate, circular or cyclic hunt groups.
An incoming call will ring for the duration of the member no answer timer and if unanswered, move on to the next
member and restart the timer. This will continue for the duration of the group no answer timer. When the group no
answer timer elapses the hunt will move onto the next designated hunt group and continue hunting according to
the new group’s settings.
If the member no answer timer is set to 0, the busy hunting mode will be used ( the hunting mode used in software
levels up to CPC-EX ).
If all members are busy the call will wait at the extension it was directed to until the member no answer timer
elapses at which point it will hunt again.
