Description: This attribute indicates the current availability of the member. The higher the value, the more available the member is perceived to be. A value of 0 indicates the member is unavailable.

A member must be considered 'available' by the hunt group in order to receive a call, regardless of the selection policy in use. The hunt group members report whether or not they are available to receive calls to the hunt group. Some services base their availability on unused logical channels, others on bandwidth or memory capacity.

During initialization, the hunt group assumes all of its members are equally available and sets their availability value to the maximum of 4095. Similarly, a new hunt group member added to an existing hunt group has its availability value initialized to 4095. This ensures that members which have not reported their availability to the hunt group are tried in order to trigger the member to report its true availability.

The availability of a member can change in the following ways: - Hunt group members can report their availability to the hunt group using a DPRS availability packet. - A network operator can temporarily change the value by the Set command. This change remains in effect until changed again by any of these ways. - The hunt group resets a member's availability to the maximum of 4095 if it has been 0 for at least 2.5 hours. This ensures that 'lost' availability information does not prevent a member from returning to service.
