Unable to
communicate (IP
fax (SIP))
Unable to
communicate (IP
fax (SIP) via VoIP
gateway)
IP fax (SIP)
transmission
takes long time.
15
458
Symptom
The Authentication/
Accounting feature is being
used and the fax is being sent
directly from the computer.
IP fax (SIP) is being received.
The network relay device such
as a switch, router, and
firewall cannot go through
the port of the machine.
The IP filter setting of the
machine is incorrect.
The Ethernet cable has been
unplugged for more than one
minute.
The registration of VoIP is
incorrect.
The specified VoIP gateway
in a network is not active.
The settings on the VoIP
gateway are incorrect.
The destination G3 fax
machine is abnormal.
The priority of the IP packet,
which is sent from the
machine, on the network
relay device (such as a switch
and router) is low because the
QoS setting of the machine is
invalid.
A large amount of
communication data loss
occurs because the queue
(buffer) assigned to each QoS
of the network relay device
(such as a switch and router)
is low.
Cause
When the Authentication/Accounting feature
is used and you send a fax directly from the
computer, you must set the user ID and
passcode registered on the machine to the
fax driver.
For details on the Authentication/Accounting feature,
refer to "Authentication and Accounting Features"
(P.409). For details on how to directly send a fax from
the computer, refer to "12 Computer Operations" >
"Sending Fax" in the User Guide.
The number of simultaneous connections for
IP fax (SIP) is one. The machine cannot send
and receive an IP fax (SIP) at the same time.
Wait until the receiving completes, and then
try sending again.
Enable the port for IP fax (SIP) of the
network relay device.
Add the IP address of the SIP server to the
permitted IP address of the machine in the
environment where the SIP server is used.
Set [IP Filtering] under [Properties] tab >
[Security] using CentreWare Internet
Services.
When Register recovery on the SIP server is
completed, the registration succeeds. No
measure is required.
Register the correct VoIP gateway on the
machine.
Consult your network administrator on the
VoIP gateway condition.
Consult your network administrator on the
VoIP gateway settings.
The data cannot be sent if the G3 fax
machine of the recipient is turned off. Call
the recipient to confirm the machine
condition.
Increase the value for [Prioritize T.38 IP
Packets] according to your network
environment.
For more information on [Prioritize T.38 IP Packets],
refer to "Prioritize IP Packets / Prioritize IP Packets
(Ethernet 1), Prioritize IP Packets (Ethernet 2)" (P.216).
Set an appropriate parameter on the network
relay device for your network environment.
