Implementations described herein may provide fax terminals that can communicate directly with one another over packet-based networks. In one implementation, a fax device may include a network connection configured to connect the device to a packet-based network. The fax device may further include a control unit. The control unit may, in response to a user command, transmit a facsimile document via the network connection and the packet-based network. The fax device may be implemented as a single integrated facsimile appliance.
