About IP Fax (SIP)
IP Fax (SIP) refers to the process of sending and receiving faxes using an IP Network in a
corporate intranets.
The process is compliant with the T.38, an ITU recommendation. Because IP Fax (SIP) uses
existing corporate intranets, the transmission is less expensive than G3 fax transmission
using public telephone network.
Note •The communication between IP Fax (SIP) devices are available for our compatible machines in a
corporate intranet. (Able 1407 is not available.) Hereinafter, IP Fax (SIP) device is referred to as our
IP Fax (SIP) compatible machine.
IP Fax (SIP) can be configured with SIP server and VoIP Gateway. The functions of the
devices are as follows:
îš„ SIP Server
Using a SIP Server, IP Fax designation can be designated by SIP user name and telephone
number. Main features of a SIP server are:
z
Receives address information of the machine in the IP network, and register the address
in the database (registrar server).
z
Relays request and response from the SIP client (proxy server).
îš„ VoIP Gateway
VoIP gateway allows the machine to relay fax communications between the IP network and
the public telephone network. A VoIP gateway is required for communicating with a G3 Fax
device.
Note •Cisco MCS7816H3 (Cisco Unified Communications Manager 6.1 is installed) is validated as a SIP
server available for the machine.
• Cisco CISCO2801-V/K9 (IOS 12.4) is validated as a VoIP gateway available for the machine.
• For more information on configuration of SIP server and VoIP gateway, contact our Customer
Support Center.
• The communication mode supported by IP Fax (SIP) is G3.
