Hunt Group allows a caller to automatically find an available callee from among a group of
extensions. You may assign some extensions to a Hunt Group. The incoming call will search
for the first available extension. Each extension will be tried until a “free” extension is
reached. If an IP phone is busy or hasn’t registered its extension to VigorIPPBX 2820 yet, its
extension will be skipped. The caller hears the busy tone only when all lines are engaged.
Vigor IPPBX 2820 supports up to 10 Hunt Groups. Up to 20 extensions can be assigned to
each Hunt Group. And each extension can be assigned to more than one Hunt Group.
There are two modes (Hunt Rule) supported by Vigor IPPBX 2820, Simultaneously and
Sequentially .
Simultaneously — If an incoming call rings on a Hunt Group, all extensions belong to this
group will ring except for the IP phones which are busy or offline.
Sequentially — If an incoming call rings on a Hunt Group, the first extension in the list is
tried. If the call is not answered within 15 seconds, it will move to the next available
extension in the list. The IP phones which are busy or offline will be skipped.
Example 1 for Simultaneously
Extension 100 is configured as a Hunt Group’s extension number. When someone calls 100,
Vigor
IPPBX 2820 tries to ring 101, 102 and 103 simultaneously at once.
Ext 101 is busy, no ring
Ext 102 rings - answers call
Ext 103 is available for next call – no ring
Example 2 for Sequentially
Extension 200 is configured as a Hunt Group’s extension number. When someone calls 200,
Vigor
IPPBX 2820 tries to ring 201 then 202 then 203 then 204.
Ext 201 rings - no answer, then moves to next
Ext 202 is busy, no ring and moves to next
Ext 203 rings - answers call
Ext 204 is available for next call – no ring
