Fax servers are products which can send and/or receive fax messages on behalf of a company or work group with the general aim of improving productivity and reducing the need for individual fax machines.
They exist in roughly two categories:
Software only - where it's up to the user to integrate components themselves (chassis, OS, fax cards etc.) and
Turnkey - where the system is supplied as a complete unit and is generally installed and provided by a single vendor.
