Set Telephone Line Compatibility for Interference and VoIP Systems

Related Models: MFC-L2710DW/MFC-L2730DW/MFC-L2750DW/MFC-L2750DWXL

Problems sending and receiving faxes due to possible interference on the telephone line may be solved by

reducing the modem speed to minimize errors in fax transmission. If you are using a Voice over IP (VoIP)

service, Brother 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.

• Telephone providers frequently bundle VoIP together with Internet and cable services.
