Home > Troubleshooting > Telephone and Fax Problems > Set Telephone Line Compatibility for Interference and VoIP Systems


Problems sending and receiving faxes due to possible interference on the telephone line may be solved by lowering the modem speed to minimize errors in fax transmission. If you are using a Voice over IP (VoIP) service, Fuji Xerox recommends changing the compatibility to Basic (for VoIP).
VoIP is a type of phone system that uses an Internet connection, rather than a traditional phone line.
Fuji Xerox does not recommend the use of a VoIP line. VoIP limitations in general can cause some functions of the fax machine not to work correctly.
