Almost every fax in the world is connected to an analogue telephone line or analogue PBX extension.
When it comes to choosing a Fax Server the Fax Servers Quarto or Octo are a logical choice, since both models are connected to the same analogue lines you already use.
After the installation you will really experience the difference between a Fax Server and an old fashioned Fax machine: There is no need for paper or toner or maintenance anymore.
What might be even more important: Faxes can be sent from every PC workstation. incoming faxes are automatically routed to your e-mail inbox and all sent and received faxes are kept in a comprehensive archive.
