How do we clean up sound with PulseEffects?

We've been on Zoom calls now for a while and have a friend with whom we talk on Zoom. His voice is really distorted and difficult to understand. We've installed PulseEffects but are at a loss as to where to begin to "experiment" in order to clean it up. We've recorded part of the most recent conference in order to have something to experiment on but going hit-and-miss doesn't seem to be getting it. Can anyone suggest a step-by-step approach to this clean up effort? Here's our specs...
