About Fax Routing Methods

A fax routing method is a procedure defined by a fax routing extension. Fax routing methods can include, but are not limited to, printing faxes, storing faxes, and manipulating received fax files. The fax service calls the fax routing methods, in order of priority, when the service receives a fax document.

A fax routing extension can support multiple fax routing methods, but the extension must export one uniquely named FaxRouteMethod function for each routing method. For more information, see Routing a Fax.

The routing extension must create a registry subkey for each fax routing method the extension exports. For more information, see Fax Routing Extension Registration.

A fax routing method can perform multiple operations; for example, the method can read the received fax file and convert it from a graphics file to an editable text file. A fax routing method cannot delete or modify the original Tagged Image File Format, Class F for facsimile (TIFF Class F) file. For more information about TIFF files, see Fax Image Format.
