I need to automate the process. We are using this for a faxing application and it must work in a multi-user environment. Frx2any produces tifs and bmps but they are not monochrome I know WinFax is a crap under XP as they did not continue to work on their COM object and it simply does not work under XP (at least the whole sending). However creation of Fax-Files should work. Maybe use an older version I think they work better.
Another option would be to use TOBIT - Faxware or David. This can be highly controlled from the outside. We do sell it and it's a really professional product (expensive though). Completely ClientServer, thousand users, no problem. 64 FaxLines, if You like. SMS and all that stuff, replication services etc. see
