Notes and Restrictions for IP Fax (SIP)
This section describes notes and restrictions to observe when using IP Fax (SIP).
îš„IP Fax (SIP) Feature
z
In IP Fax (SIP) transmissions, protocols used for call connection are SIP and for data
communication is T.38. Other IP Fax transmissions protocols, such as H.323
standard and deemed voice communication method, are not supported.
z
IP Fax (SIP) cannot be performed on SSL/TLS communication.
z
In IP Fax (SIP) transmissions, authentication is performed between the machine and
a SIP server.
The authentication supports the digest authentication only. NTLM and the other
authentication methods are not supported.
z
The number of simultaneous connections for IP fax (SIP) is one. The machine cannot
perform sending and receiving an IP fax (SIP) at the same time.
z
Up to two SIP servers are available for a registrar server and a proxy server,
respectively.
z
The IP address of a SIP server can be resolved using DHCP or DHCPv6 (The IP
address of the SIP server must be set to the option number "120" of a DHCP or a
DHCPv6 server). However, observe the following considerations:
- If an IP address is automatically resolved using DHCP in an IPv4 environment, set
[IPv4 - IP Address Resolution] to [DHCP] or [DHCP/Autonet].
- Even when an IP address can be resolved automatically using DHCP or DHCPv6,
port number, login user name, login password, and server type cannot be resolved
automatically. Configure these items manually.
- If an IP address is resolved automatically, the same IP address is assigned to a
proxy server and a registrar server. If you use different IP addresses for a proxy
server and a registrar server, configure the IP addresses manually.
- If multiple IP addresses are resolved automatically, assign the first IP address to
a primary proxy/registrar server and the second to a secondary proxy/registrar
server. The third and subsequent addresses are not used.
z
Only ToS (IP Precedence/DSCP) is supported as a QoS control method, and other
QoS controls including CoS are not supported. Set the priority of IP packet
transmission in [Prioritize T.38 IP Packets] to perform QoS control for the machine.
îš„Recipients
z
IP Fax (SIP) communications are available only among the IP Fax (SIP) - enabled
machines manufactured by Fuji Xerox that are installed in an intranet. However, Able
1407
λ is unsupported.
îš„SIP Server
The following e-mail applications can transmit e-mails between the machine and a
computer:
MCS7816H3 (Cisco Unified Communications Manager 6.1 must be loaded)
manufactured by Cisco Systems, Inc. is a SIP server we have validated operation.
z
If you use a SIP server manufactured by Cisco Systems, Inc., only UDP can be used
as T.38 protocol.
z
SIP servers does not work on IPSec communications.
z
SIP servers does not work in an IPv6 environment.
