Advantages of Fax servers

[edit] Advantages over paper fax machines
Users can send and receive faxes without leaving their desks.
Any printable computer file can be faxed, without having to first print the document on paper.
The number of fax lines in an organisation can be reduced, as the server can queue large numbers of faxes and send each when any of a number of lines is free.
Faxing capability can be added easily to computer programs, allowing automatic generation of faxes.
Transmitted faxes are more legible and professional-looking.
There is less clutter of office equipment; incoming faxes can be printed on a standard computer printer.
Printer jams on malfunctioning fax printers may be reprinted without being re-faxed.
Faxing may be monitored and/or recorded, so that users may be allocated quotas or charged fees, or to ensure compliance with data-retention and finacial laws.
Fax Servers can be located centrally in an organisation's data centres providing resilience and Disaster recover facilities to a traditionaly desktop technology.
Incoming junk faxes are not as much of a problem; the server may maintain a blacklist of numbers it will not accept faxes from (or a white list listing all the numbers it will accept calls from), and those that do get through do not waste paper.

[edit] Public fax services
There are many companies (internet fax providers) operating fax servers as a commercial public service. Subscribers can interact with the servers using methods similar to those available for standard fax servers, and would be assigned a dedicated fax number for as long as they maintain their subscription. Fees are normally charged on a flat monthly rate, with a limit on the number of fax pages sent and/or received. Organisations, and individuals in particular, may find this more convenient or cost-effective than operating their own fax systems.

[edit] Integrated fax programs
An integrated fax program is a complete set of faxing software which operates on a single computer which is equipped with a fax-capable modem connected to a telephone line. Its user interfaces may be similar to those used to communicate with fax servers, except that since the entire operation takes place on the user's computer the user may be made more aware of the progress of the transmission. Integrated fax programs are aimed at consumers and small organizations, and may sometimes be bundled with the computer's operating system
