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. To use your machine to send and receive faxes on a VoIP
system, connect one end of your telephone cord to the jack labeled LINE on your machine. Connect the other
end of the telephone cord to a modem, interface box, phone adapter, splitter, or other such device.
If you have questions about how to connect your machine to the VoIP system, contact your VoIP provider.
After you have connected your machine to the VoIP system, press
[Hook]
on the Touchscreen or the Hook
button on the control panel to verify the machine has a dial tone. If the machine does not have a dial tone, call
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.
