For whichever input channel you have the Caller connected to, turn the
corresponding Aux control to minimum (usually hard left). All other Aux
controls should be set for what you want to send to the phone line. Each
Aux Send bus is completely separate from all other outputs, so these Aux
controls will not affect what is heard on the Main outputs or on any other
Aux buses. This Aux Send bus should be pre-fader, so you can use the
fader controls to set the levels of each channel to the main output.
