Hi. I am not sure what kind of support is really desired in this case. RTPProxy by design is pretty codec-agnostic as far as packet forwarding goes, so it should at least theoretically handle any kind of codec including OPUS. Then there is a support for generating MOH/announcement type streams, that indeed needs some basic understanding of the codec parameters to make it working. There is also support in the tools (makeann and extractaudio).

Could you please be more specific, thanks!

Transcoding and MOH - my idea was to build an MOH system using RTPP, but OPUS support seems to be lacking there.
