Internet fax uses the internet to receive and send faxes.
Internet faxing (or "online faxing") is a general term which refers to sending a document facsimile using the Internet, rather than using only phone networks (traditional faxing).
Depending on the specific method/implementation (see below), advantages of using the internet can include
no extra telephone line required for the fax
paperless communication, integrated with email
send and receive multiple faxes simultaneously
reduction in phone costs
Note that depending on which method is used, suitable equipment and/or the use of a gateway is required (see below).
