Select IP FAX Delay Level
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
