Fax over the Internet

You may subscribe to a low cost phone service that allows you to send and receive
faxes with your device by using the Internet. This method is called Fax over Internet
Protocol (FoIP). You probably use a FoIP service (provided by your telephone
company) if you:

Dial a special access code along with the fax number, or

Have an IP converter box that connects to the Internet and provides analog phone
ports for the fax connection.


You can only send and receive faxes by connecting a phone cord to the

port labeled "1-LINE" on the device and not from the Ethernet port. This means
that your connection to the Internet must be done either through a converter box
(which supplies regular analog phone jacks for fax connections) or your telephone

Some Internet faxing services do not work properly when the device is sending and
receiving faxes at high speed (33600bps). If you experience problems sending and
receiving faxes while using an Internet fax service, use a slower fax speed. You can
do this by changing the Fax Speed setting from High (the default) to Medium. For
information on changing this setting, see

Set the fax speed


You should also check with your telephone company to make sure their Internet faxing
service supports faxing.
