  Traditionally, sending and receiving faxes required a dedicated machine connected to a fax-only phone line. Several packages of computer software, however, remove one or both of these requirements and allow faxes to be sent using software. This can lead to significant equipment cost savings and enable you to consolidate your communications tools onto one computer.
  
  

Fax Machine

• Fax Machine is software that is designed to replace the physical device after which it is named. The program allows users to send and receive faxes using the computer alone. It can be interfaced with a scanner, allowing paper documents to be transferred easily over any fax line. Additionally, users can send faxes from virtual sources. Any printable computer file, including spreadsheets and e-mails, can be transferred to Fax Machine and faxed.
  
  Additional features of Fax Machine include a junk fax filter, which operates in a similar manner as a junk e-mail screener. Incoming faxes from spam sources are automatically deleted before they are printed, saving time and paper. Incoming faxes can also be forwarded automatically over e-mail, allowing users to receive correspondence even when they are away from the office. Fax Machine is able to operate on Windows NT, 2000, XP, Vista and Windows 7.
  
  

FaxTalk Messenger

• FaxTalk Messenger is a full software communications package that combines fax and voice capabilities. For faxes, the software completely replaces a standard fax machine and can save multiple incoming faxes in digital form. The voice capabilities of FaxTalk Messenger allow it to function as a virtual answering system, taking messages from incoming callers.
  
  One powerful feature of the software is the on-demand fax response system. This allows phone callers to choose information, such as real estate listings or business details, from a list of options. The software can then fax detailed information to the caller's location, all automatically at any hour of the day. FaxTalk Messenger is compatible with Windows 2000, XP, Server, Vista and Windows 7.
  
  

VentaFax

• VentaFax allows users to replace traditional fax machines with flexible messaging software. The program can receive and send both gray-scale and color fax documents. Information on incoming faxes can be accessed remotely over the phone, allowing busy users to check for information on new documents while traveling.
  
  The software's interface is designed to be very easy to use, and features the same layout as a standard fax machine. VentaFax can send a fax from any computer program that is able to print. The software will work with Windows 98, 2000, XP, Vista and Windows 7.
  
  

FaxTools eXPert

• FaxTools eXPert allows any computer with a phone connection to send and receive faxes. Additionally, the software is able to transfer faxes from any high-speed Internet connection, including cable and satellite. This feature means that users can access their faxes even when a traditional phone and fax line is not available.
  
  The program includes built-in support for all major fax modems and most digital scanners, allowing paper documents to be sent over fax quickly and easily. Fax newsletters, which are able to be sent to hundreds or even thousands of recipients, can also be easily created. FaxTools eXPert is compatible with Windows 98, Millennium, 2000 and XP.
