An exemplary elevator system includes a first controller configured to recognize a hall call signal that indicates a passenger's desire to board an elevator car at a particular landing. The first controller is associated with at least one elevator car for assigning a hall call request to that elevator car. A second controller is configured to recognize a destination request that indicates a passenger's desire to be carried to a particular level. The destination request originates outside of an elevator car. The second controller is associated with at least one elevator car for assigning a destination request to that elevator car. The second controller is configured to determine whether a selected condition will be satisfied if a received destination request is serviced by an elevator car associated with the second controller. The second controller handles the received destination request in that manner if the condition will be satisfied. A cross dispatcher is configured to communicate with the second controller and to handle the destination request. If the condition will not be satisfied, the cross dispatcher provides an indication of a hall call signal corresponding to the received destination request to the first controller.
