Well there's your first problem. If you are calling two devices with OPUS enabled, Asterisk should be passing the codec through directly and not doing any type of conversion.
You right, this is not good.
I was able to configure FreePBX to NOT do any converting with opus2opus calls, but this problem still hit me - sometimes call quality drops when using only opus and most calls have bad quality when opus converted to something other codec (even G722).
Now i use G722 only and feel good with this codec.
