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.
