Electronic Fax

Internet fax, e-fax, or online fax is a general term which refers to the use of the Internet to send a document fax, rather than using only phone networks (traditional faxing) with a fax machine. The term "Internet fax" encompasses "web fax" and "email fax," along with VoIP fax, which refers to the use of Voice over IP to send a fax. However, Internet fax should not be confused with IP fax.
