Yes, some of our customers use the fax machine and FaxTalk together on the same telephone line by using a telephone splitter. While you can use both, they operate independently. We recommend setting your fax machine to answer calls in 3 or 4 rings, and FaxTalk set to answer in 2 rings. If your computer is turned off, you can still receive faxes on the physical fax machine but they will not be stored or displayed in the FaxTalk software.
