Ringback is just another name for undershoot. I don't know why someone had
to invent another name for something that already had a name.
When you have undershoot and you use series terminations, the terminator
value it too high or the output impedance of the driver is too high. When
you have undershoot and you use parallel terminations, the value of the
terminator is too low. Fix which ever problem you have by changing the
value appropriately.
