I am wondering how does the current voice codec Wideband AMR compared to Opus? And why aren't we using Opus on 4G LTE All packet network instead when the Internet has decided on Opus.

Would switching to Opus be hard ( aren't these spec defined, or could software be updated to use it? ) ( If LTE is all packet based i see no reason why not possible )

And on such as low bitrate, would voice cancellation, multiple microphone helps more then a codec change in voice quality?
