Comments
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
