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.
