Seems like updox would have an optional program that you could install on your computer with a faxmodem, and have it securely send Updox the faxes over the internet.
You can. I do this all the time using Updox from my Mac at home (since I can't run AC on a Mac) to import documents into AC on my work PC. You don't need to have a separate program, just fax the document from your computer to the fax # Updox assigns you, and it shows up in the Updox workspace. From there it can be signed, amended, faxed, emailed, saved as a PDF, printed or imported into AC.
