Changed repeater setup to: mic to 1, 2 to 1, 2 to headset, Google voice to Line 2, then set RB to Line 1 input. UPDATE: seem to have it working but with drawbacks. In theory, if line 3 is my input, and it has MIC coming to it, and LINE TWO coming to it (if Skype/GV outputs to TWO) then I have my repeaters for LINE TWO to phones, shouldn't I only hear caller and presumably music/sound files? I have not been able to broadcast my voice at all without mic button pressed, so I have not even tested calls.
UPDATE: Ok, tried 1, 2, and 3 for input with above setup, with both output to encoders only selection on and off, and anytime I can get my voice to broadcast, I hear it back through my phones. Then, I get only the caller's audio coming in and I presume I'd still hear music/sound effects. So then, I'd have to set up I think 3 for mic in on that third screenshot you showed. Ok, I actually have a bat file for that so what I"ll be doing is running VAC: mic to 1, 1 to 3, 2 to 3, 2 to phones.
