IsoFax is designed so that server and client functions are independent which should reduce the load on the server eliminating the need to dedicate a machine to being a fax server.
The server monitors the queue of faxes submitted by clients, the pool of modems, and logs all fax activity. For business sending faxes to large distribution lists, IsoFax offers server-side coversheets to reduce the load on the client. Faxes may be submitted to the server by standard GUI fax clients or through background processes using the IsoFax toolkit/API. Faxes can also be submitted by SMTP email, and MIME attachments can be easily processed into faxes.
