Set Telephone Line Compatibility for Interference and VoIP Systems

Related Models: MFC-B7715DW
Problems sending and receiving faxes due to possible interference on the telephone line may be solved by
reducing the modem speed to minimise 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.
