Which modems does GFI FaxMaker support?

If you rely heavily on faxing and it is an integral part of your business, GFI Software recommends a professional fax hardware or virtual Fax over IP device, versus a modem.

If you choose to use a modem with GFI FaxMaker, you can do so either by using the GFI Fax modem drivers which supports class 1 / 1.0, class 2 and class 2.0 modems, or the Microsoft fax modem drivers.

The following modems have been used with GFI FaxMaker:
