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/AutoIP].
- 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 IP Packets] to perform QoS control for the machine.
îš„ Recipients
z
The communication between IP Fax (SIP) devices is available for our compatible
machines in a corporate intranet. (Able 1407 λ is not available.) For information on the
compatible machines, contact our Customer Support Center.
îš„ SIP Server
The following e-mail applications can transmit e-mails between the machine and a
computer:
z
Cisco MCS 7800 series (Cisco Unified Communications Manager 6.0/6.1/7.1/8.0 is
installed) is validated as a SIP server available for the machine.
z
The gateway may not work properly over an analog line depending on your environment.
