About IP Fax (SIP)
IP Fax (SIP) is a process of sending and receiving faxes using an IP Network in a corporate
intranet.
This process is compliant with T.38, which is an ITU recommendation. IP Fax (SIP) uses the
existing corporate intranet making communication less expensive than the G3 fax
communication that uses public telephone network.
Note • The communication between IP Fax (SIP) devices is 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 the SIP Server, you can specify the recipient with the SIP user name and the telephone
number. The main features of the SIP server are:
z
Receives address information of the machine in the IP network, and registers the address
in the database (registrar server).
z
Relays requests and responses from the SIP client (proxy server).
îš„ VoIP Gateway
The VoIP gateway, which is required for communicating with a G3 Fax device, allows the
machine to relay fax communications between the IP network and the public telephone
network.
Note • The supported SIP server is Cisco MCS7816H3 (Cisco Unified Communications Manager 6.1).
• The supported VoIP gateway is Cisco CISCO2801-V/K9 (IOS 12.4).
• For more information on the configuration of the SIP server and the VoIP gateway, contact our
Customer Support Center.
• The communication mode supported by IP Fax (SIP) is G3.
IP Fax (SIP) can be used in the following four connection configurations:
How to input the IP Fax destination depends on the connection configuration.
