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:
• Reducing communication costs
• Communicating between IP-Faxes at higher speed than by standard fax
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.
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).
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 Initial
Settings.
You can receive IP-Faxes in the same manner as standard faxes. For details about reception, see “Types
of Reception”.
