Calls to a Congested Hunt Group
A hunt group is defined as congested if no members are available to answer the call and the call cannot be queued, either because no queue positions have been defined for the group, or the maximum number of calls in the queue has been reached.
During these conditions the incoming calls to the hunt group can overflow to another destination. The destination can either be an internal number (for example, another hunt group), a private network number or an external destination (stored as a common abbreviated number). At overflow to an external destination, the call will be treated as if external Follow-Me has occurred and the overflowed hunt group will be charged.
Multiple overflow attempts are allowed for a hunt group call, that is, a call to a hunt group which is overflowed to another hunt group can continue overflowing if the next hunt group also fulfills the overflow conditions.
At maximum number of overflow attempts or there is no overflow position programmed a NO PROGRESS message is sent to the calling party and suffix usage is not possible.
The possibility to divert calls to a congested hunt group is described in the section Diversion of Hunt Group.
