1. A method for terminating a queued call from a caller to a subscriber line, the call processed by an Advanced Intelligent Network (AIN) having at least one cental office switch and a service control point (SCP) in electrical communication with a plurality of subscriber switches via a signaling network, the method comprising:

  • providing an intelligent peripheral in electrical communication with the at least one cental office switch and the SCP, the intelligent peripheral equipped with queuing functionality;

    determining that the call has been queued within the intelligent peripheral for a determined amount of time;

    requesting that the caller perform an action to remain in queue;

    if the caller does not perform the requested action, dequeuing the call;

    monitoring call signaling to detect a terminating attempt trigger;

    launching a query at the SCP for receipt by the intelligent peripheral requesting the queue status of the subscriber line in response to the detected terminating attempt trigger;

    forwarding the call to the intelligent peripheral to be added to the queue in response to a determination that the queue is active;

    delivering the call to the subscriber line and setting a next event list trigger to determine the status of the subscriber line in response to a determination that the queue is empty;

    connecting the call to the subscriber line in response to a determination that the line is idle; and

    forwarding the call to the intelligent peripheral to be placed in queue in response to a determination that the subscriber line is busy.
