Symptom
IP fax (SIP) The priority of the IP
transmission packet, which is sent from
takes long time 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.
A large amount of
communication data loss
occurs because the
communication rates
(10M/ 100M/1000M)
differ on two sides of the
network relay device (such
as a switch and router).
A large amount of
communication data loss
occurs because the
communication
parameters (such as input
gain, output attenuation,
echo setting) of the VoIP
gateway are inappropriate
for the network
environment.
IP fax (SIP) machine
isconnected to the data
network where the
telephone and data
networks are operated
separately
Cause
Increase the value for [Prioritize
IPPackets] according to your network
environment.
Reference
For more information on [Prioritize IP Packets],
refer to "Prioritize IP Packets / Prioritize IP Packets
(Ethernet 1), Prioritize IP Packets (Ethernet 2)"
(P.212).
Set an appropriate parameter on the
network relay device for your network
environment.
Use the same communication speed
within the network.
Set appropriate communication
parameters on the VoIP gateway for your
environment.
Configure the QoS setting for the entire
network environment and control traffic.
Set [Prioritize IP Packets] for QoS of the
machine.
