Fuji Xerox ApeosPort-V C5575 Administrator's Manual page 737

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.
Recipients
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.
SIP Server
The following e-mail applications can transmit e-mails between the machine and a
computer:
 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.
 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.
 SRST that works on routers such as CISCO2801 manufactured by Cisco Systems, Inc. is
not supported.
 Cisco Call Manager Express that works on routers such as CISCO2801 by Cisco Systems,
Inc. is not supported
If you use a SIP server manufactured by Cisco Systems, Inc., you can specify only IPv4

address character strings of the SIP server on the right side of @ in [SIP User ID (Sign-in
Name)]. If you specify IPv6 address character strings, FQDN character strings, and SIP
domain name character strings, the SIP server does not work.
 When a SIP server is configured as a SIP terminal of the machine on the server, if settings
other than specified are configured, the SIP server does not work as the SIP terminal.
 For a SIP server manufactured by Cisco Systems, Inc., an address retention period is fixed
to 120 seconds. This value cannot be changed even if Timer Register Expires value is
changed.
VoIP Gateway
 Cisco ISR 2800 series (with IOS 12.4) is validated as a VoIP gateway available for the
machine.
 The gateway may not work properly over an analog line depending on your environment.
 If you use a VoIP gateway manufactured by Cisco Systems, Inc., only UDP can be used as
T.38 protocol.
 VoIP gateways do not work on IPsec communication.
VoIP gateways do not work in an IPv6 environment.

 If settings other than specified by Fuji Xerox are configured for a dial peer or a voice port
on a VoIP gateway, the VoIP gateway does not work.
 If a part of transferred data is lost on a network, a part of image may be missing or be
getting stacked. To avoid these, the ECM mode is effective. The machine can always use
the ECM mode, however, you cannot use the mode depending on the VoIP gateway
settings. Consult your network administrator whether the ECM mode is available.
