Abstract

An external accessory is added to an automatic call director to ensure first in first out operation for connection to primary resources when secondary resources are accessed prior to primary resources. A controller intercepts resource requests for the call director and manages an auxiliary queue to provide first in first out operation. The resource requests are returned to the call director queue once first in first out is guaranteed.
