There are 4 OGMS that Get you to put in your number, Read your number Back, Give you the option to change your number, then sends the fax.
In order to get the Fax sending to work you need to setup faxing in windows first.

The Fax.exe will use the windows settings to send the FAX. So as long as your sending of faxes is working, then the fax plugin will use the same method.
The fax.exe file needs to be put in 'c:\program files\nch swift sound\ivm' as thats where the OGM is pointing to.
The OGM is also looking for a file called fax.tif on C: drive.

You can place the file in the root of C: drive or just change the location in the OGM. 'OGM Send Fax -> advanced Tab -> Open Run EXE or plugin settings'.

You can download the Fax Plugin from http://www.nch.com.au/ivm/plugins.html
