Raise the level by selecting a higher setting if too
many transmission errors are occurring on the
network.
If TCP/UDP is enabled on the network, raise this
setting on the T.30 machine. Increasing the delay
time allows the recovery of more lost packets.
If only UDP is enabled, increase the number of
redundant packets.
Level 1~2: 3 Redundant packets
Level 3: 4 Redundant packets
