Can Fusion Client SDK handle transcoding when needed?

Yes. In addition to port muxing and handling of encryption/decryption for WebRTC endpoints, the Media Broker transcodes between VP8 and H.264 when required. The Media Broker also transcodes G.711 and Opus HD audio codecs into G.729 and G.711 if needed in the contact center.  This guarantees compatibility between WebRTC endpoint and immersive, desktop and traditional video and VoIP endpoints.
