Communications
other than IP fax
(SIP) become
slow while IP fax
(SIP)
transmission is
executed.
The priority of IP packet,
which is sent from the
machine, on the network
relay device (such as a
switch and router) becomes
higher than necessary
because the QoS setting of
the machine is invalid.
Or, large amounts of buffer
space is occupied.
Decrease 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 T.38 IP Packets"
(P.204).
IP fax (SIP) machine is
connected to the telephone
network where the
telephone and data
networks are operated
separately.
Configure QoS setting for the entire
network environment and control traffic.
Set [Prioritize T.38 IP Packets] for QoS of
the machine.
For more information on [Prioritize T.38 IP
Packets], refer to "Prioritize T.38 IP Packets"
