Problems sending and receiving faxes due to
possible interference on the telephone line
may be solved by lowering the modem speed
to minimize errors in fax transmission. If you
are using a Voice over IP (VoIP) service,
Brother recommends changing the
compatibility to Basic (for VoIP).
• VoIP is a type of phone system that
uses an Internet connection, rather
than a traditional phone line.
