Hunting Groups
Description
Hunting allows calls to be automatically transferred among a preselected group of phones. If a phone
is busy or there is no answer in a set amount of time, the call will hunt to the next phone in the hunt
group.
A phone assigned to a hunt group is called a member. Up to 20 members can be assigned to a hunt
group. Up to 12 hunt groups are available per CCU.
Several methods of station hunting are available. Some methods require use of a pilot number (a
fictitious extension number) while others start by a direct call to a hunt group member.
The System supports the following hunting groups:
• Pilot Terminal Hunt Group
• Pilot Distributed Hunt Group
• Switch Back Hunt Group
• Circular Hunt Group
• Next Extension/Hunt Group
Pilot Terminal Hunt Group
Pilot Terminal Hunt Group directs calls to a pilot number. The System begins with the first member
and hunts through the group for the first available member to receive the call. If no member is
available (extension is busy or there is no answer for a specified amount of time), the call is queued
for the first member to become available. You can also set the Queuing Timer to specify how long the
System will search the initial hunt group before beginning to search the next hunt group or extension.
The main advantage of this type of hunting is that the same hunting order is taken for all calls. This is
useful in presenting calls to selected members first.
Pilot Distributed Hunt Group
Pilot Distributed Hunt Group directs calls to a pilot number. The System reviews who received the
last call and begins hunting with the next member. If the last member in the group is reached and no
