Abstract: Embodiments of the present invention provide a method, system and computer program product for peer-to-peer fax messaging. In an embodiment of the invention, a multi-modal peer-to-peer messaging method can include receiving in a processing node a job request to process a message by way of an ingress node from one type of messaging system for delivery to another type of messaging system by way of an egress node. The method also can include extracting metrics from the job request pertaining to availability of peers to the node and updating a local data store of metrics in the processing node with the extracted metrics. The method yet further can include processing the message according to the job request and setting an availability for the processing node in the local data store of metrics. Finally, the method can include forwarding the processed message and the metrics in the local data store to the egress node for transmission to the different type of messaging system.

Abstract: A spam fax filter which has been configured in accordance with the present invention can include a fax transformation processor configured to transform rasterized fax images into non-rasterized representations of fax images. The spam fax filter further can include a knowledge base of known spam characteristics. Finally, the spam fax filter can include a comparator configured to compare non-rasterized representations of fax images produced by the fax transformation processor to the characteristics in the knowledge base to detect spam fax in the spam fax filter.

Abstract: An optimal call routing system and method based upon pre-configured heuristics. In one aspect of the invention, a heuristic routing method can be provided in which a request to transmit an electronic document to a target destination can be received. A set of statistics associated with the target destination can be retrieved from a data store. A heuristically optimal route can be selected from the set of statistics through which the electronic document can be transmitted to the target destination. Subsequently, the electronic document can be transmitted to the target destination over the selected heuristically optimal route. Finally, statistics relating to the transmission can be collected and stored in the data store.

Abstract: A premium messaging exchange. The premium messaging exchange can include a list of destinations supported by the premium messaging exchange. Each record in the list can include a specified destination, and a supporting external messaging system. Finally, the premium messaging exchange can include an interface to the list which can be accessed by querying external messaging systems and through which supporting external messaging systems can be identified for specific destination addresses provided by the querying external messaging systems through the interface.
