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.

NOTE: You can only send and receive faxes by connecting a phone cord to the 1- LINE port on the back of the HP All-in-One. 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 company.

The FoIP service might not work properly when the HP All-in-One is sending and receiving faxes at high speed (33600 bps). If you experience problems sending and receiving faxes, use a slower fax speed. You can do this by changing the Fax Speed setting from Fast (the default) to Medium.

You should also check with your telephone company to make sure their Internet phone service supports faxing. If they do not support faxing, you might encounter intermittent problems when trying to send and receive faxes through the Internet.
