At work we're using WinFax 10.03. Symantec no longer supports WinFax as of 2006 though, and it's becoming more and more unreliable. I know Win XP has a built-in fax program, but I don't have any experience with it. Does anyone have any suggestions for good PC faxing programs? Or experience with XP's fax capabilities, i.e. is it any good?
