IP-Fax Functions

The IP-Fax function sends or receives documents between two facsimiles directly via a TCP/IP network.

This function has the following advantages and is suitable for communication within the same LAN:

IP-Fax uses SIP and H.323 as the network protocol.

Specify an IP address or host name instead of a fax number for sending. When using a gatekeeper, specify an alias telephone number. Specify addresses of the gatekeeper or SIP server (proxy server, registrar server, redirect server) as appropriate under H.323 Settings, SIP Settings, or Program / Change / Delete Gateway in the Facsimile Features menu.

When using a SIP server, you can send by specifying SIP user name.

You can also transmit to a G3 facsimile connected to the public switched telephone network (PSTN) via a gateway (T.38-compliant).

You can receive IP-Faxes in the same manner as standard faxes. For details about reception, see “Types of Reception”.
