An Office Hunt group consists of numbers (called Members) that can be forwarded to each other. Each group uses a combination of a forward number and position. Each member has a designated forwarding number, when the first number does not answer an incoming call, the call forwards to the next member, if that member does not answer; the switch forwards the call to the next member until the call is answered. In addition, an office hunt group creates a ringing pattern; the position indicates when the member receives a call.
You first define the group, or the first member. After the group is created, you add members into the group.
