A fax server is a system installed in a local area network (LAN) server that allows computer users whose computers are attached to the LAN to send and receive fax messages.
[1] Alternatively the term fax server is sometimes used to describe a program that enables a computer to send and receive fax messages,[1] set of software running on a server computer which is equipped with one or more fax-capable modems (or dedicated fax boards) attached to telephone lines or, more recently, software modem emulators which use T.38 ("Fax over IP") technology to transmit the signal over an IP network.
Users may communicate with the server in several ways, through either a local network or the Internet.
Fees are normally charged on a flat monthly rate, with a limit on the number of fax pages sent and/or received.
Integrated fax programs are aimed at consumers and small organizations, and may sometimes be bundled with the computer's operating system.
