In a contact center, a system for processing communication events has an interaction server for managing events waiting to be routed, a routing server for routing the events, a rules engine, and a gateway server executing rules invocation logic and interacting with the rules engine. The interaction server tracks incoming events, initiates and sends a routing request to the routing server, including a special routing object, for each event that requires conformance to business rules, the routing server, executing the routing object, sends an execution request to the gateway server, which upon receipt of the request prepares a business object model (BOM), being a set of facts upon which the rules engine executes rules appropriate to the facts, resulting in routing direction for the routing server to route the event.
