Voice Over Internet Protocol (VoIP/Telephone Line Interference)
VoIP is a type of phone system that uses an Internet connection instead of a traditional telephone line. Telephone
providers frequently bundle VoIP together with Internet and cable services.
Your machine may not work with some VoIP systems. If you want to use your machine to send and receive faxes
on a VoIP system, make sure one end of your telephone cord is connected to the socket labelled LINE on your
machine. The other end of the telephone cord may be connected to a modem, phone adapter, splitter, or other
such device.
If you have questions about how to connect your machine to the VoIP system, please contact your VoIP
provider.
After you have connected your machine to the VoIP system, check for a dial tone. Lift the external telephone's
handset and listen for a dial tone. If there is no dial tone, please contact your VoIP provider.
If you are having problems sending or receiving faxes over a VoIP system, we recommend changing the
machine’s modem speed to the
[Basic(for VoIP)]
setting.
• VoIP (Voice over IP) is a type of phone system that uses an Internet connection, rather than a traditional
phone line.
• Brother 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.
