FaxBack Port Server - Manual - Manual (Page 29)

Chapter 7 – Accounts and Clients
The Port Server is designed to route faxes through it in real time, similar to a PBX or other telephone equipment.
Therefore an account must be currently logged in to send or (more importantly) receive faxes. In the case of
multiple Connection Servers, the account can only be logged in to one of the Connection Servers.
The minimum required for a valid account is an AccountId and a Password. Once created, a client can log in to the
Connection Server using the account and send faxes. The minimum required to receive faxes is to route a DID to
that account. The client will receive faxes for that DID.
AccountId and Password are each limited to 64 characters.
When using RADIUS, most of these fields will be grayed out and will display information about that user provided
by the RADIUS server.
