So what does today support FEC/PLC today? We tested two Polycom VVX phones with the opus codec, and overall thought that G.722 sounded much better than OPUS for some reason. So using Opus at 8 KHz, does that mean that there will be less or no transcoding to G.711 since its also in 8 KHz? What are most of the web only WebRTC companies using as far as OPUS goes? What bitrate and KHz? On Fri, May 5, 2017 at 8:33 AM, Brian West <brian@freeswitch.org> wrote:
None of the hardware phones do FEC/PLC last I tested, Sonus has OPUS support, but again no FEC/PLC support.

Yealink is supporting OPUS on several other models since firmware V81:

I can confirm OPUS implementation on the 'T21P E2' model.
