Network-Based Faxing

I am looking for a SIMPLE network-based faxing software where Win 95/98 clients can send their faxes over our Ethernet TCP/IP network to a fax queue “server.” This server would have the modem needed to fax. The ideal program would have fax notification to the user (in the event that fax did not get sent for whatever the reason or if the fax was successful in sending). It would also have some kind of a fax address book (just in case) and it would employ a SIMPLE interface. The fax server would have NT 4 as an OS and a good brand of modem.
