Medium (14400) v.17 (14400 baud)
Slow (9600) v.29 (9600 baud)
Cause: The fax over Internet Protocol (FoIP) service might not have worked properly when the product was
sending and receiving faxes at high speed (33600 bps).
If this did not solve the issue, try the next solution.
Solution 2: Make sure the phone cord is connected to the correct port on the product
Solution: You can only send and receive faxes by connecting a phone cord to the port labeled 1-LINE on the
product. 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.
Cause: The product was not set up properly for faxing.
If this did not solve the issue, try the next solution.
Solution 3: Make sure the telephone company supports faxing over the Internet
Solution: Check with your telephone company to make sure their Internet phone service supports faxing. If
they do not support faxing, you will not be able to send and receive faxes through the Internet.
Cause: Your telephone company did not support faxing over the Internet.
