Registration of a Fax Routing Extension

  • Article

To register with the fax service, it is recommended that a fax routing extension DLL perform the following steps.

To install an extension and register

  1. Copy the fax routing extension DLL to the location specified by the ImageName parameter to the FaxRegisterRoutingExtension function.
  2. Call the FaxConnectFaxServer function, specifying a NULL pointer in the MachineName parameter, to obtain a fax server handle to the local server.
  3. Call the FaxRegisterRoutingExtension function to register the fax routing extension DLL with the fax service. The function calls the FaxRoutingInstallationCallback function once for each fax routing method in the fax routing extension DLL.

If you install a fax routing extension by using a call to FaxRegisterRoutingExtension, you must restart the fax service to use a fax routing method exported by that extension.
