The FaxFinder® fax server is an all-in-one network attached
appliance that allows faxes to be sent and received
electronically. Inbound faxes are delivered to a recipient’s email
inbox or network folder so they can be accessed by a personal
computer or mobile device. Faxes can also be queued on a
network printer for customers who require printed copies.
A number of routing options are available to help ensure
faxes are delivered to the proper individual or department.
Outbound faxes are sent using client software, web browser,
or existing email client.
