Shawn just so you know I tried reducing volume my the VM. level 2 seems to give undistorted voice but now nothing can be heard on the outside line pretty much everything is low. Now I need to adjust the systems loss plan (damn glad that's in there) I was able to get good audio on the COs with +2.8. I know this will take some time to balance out the system, just wish I had a loss plan formula to blueprint.
