Fax Routing Extension Application Programming Interface

The Fax Routing Extension application programming interface (API) allows you to add routing functionality to the fax service. The API provides third-party software vendors with a flexible way to connect software applications that route received fax transmissions through multiple routing methods.

The first part of this overview describes the components you need to support the Fax Routing Extension API, and the functionality the API provides. It also outlines registration requirements for a fax routing extension dynamic-link library (DLL) and management of fax devices.

The following topics discuss common tasks you can perform using the fax routing extension functions:

• Initializing a fax routing extension
• Routing a fax
• Managing a fax file list
• Fax routing extension registration
• Managing fax devices
• Enumerating available fax devices

In this documentation a fax routing "method" refers to a procedure defined and supported by a fax routing extension DLL. For more information, see About Fax Routing Methods.
