Notes and Restrictions for IP Fax SIP

Notes and Restrictions
Notes and Restrictions for IP Fax (SIP)
This section describes notes and restrictions to observe when using IP Fax (SIP).
IP Fax (SIP) Feature
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.
IP Fax (SIP) cannot be performed on SSL/TLS communication.
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.
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.
Up to two SIP servers are available for a registrar server and a proxy server, 
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.
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.
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 
 is unsupported.
SIP Server
The following e-mail applications can transmit e-mails between the machine and a 
MCS7816H3 (Cisco Unified Communications Manager 6.1 must be loaded) 
manufactured by Cisco Systems, Inc. is a SIP server we have validated operation.
If you use a SIP server manufactured by Cisco Systems, Inc. only UDP can be used 
as T.38 protocol.
SIP servers do not work on IPSec communications.
SIP servers do not work in an IPv6 environment.
