A system, method, and call processing component for controlling an order of call processing among a plurality of call processing components. Each call processing component, upon receiving a call request when system resources are not available to process the requested call, creates a real queue entry in its call processing queue and sends a call-queued notification to all other call processing components in the system. The other call processing components in the telecommunication system then create a shadow queue entry in their respective call processing queues as a placeholder for the requested call. When system resources become available and the requested call is next in the queue, the call processing component that received the request de-queues and processes the requested call, and sends a call de-queued notification to the other call processing components. In response, each of the other call processing components removes the placeholder queue entry for the requested call from each call processing component's call processing queue. |
