   While the reflector works well for general audio quality, I think
echo problems are probably easier to check with another "node".  In the
past we've used another system with rat installed (desktop or laptop
running windows) and used a headset / mic for that so we could generate
sound into the local node and hear the results.  You should turn up the
listen volumes on the system used to test with though so you can hear

   Of course, there is the test room and you can often get other sites
to join you there for some testing.
