Does RTMP SIP Gateway support G.722 codec?

Flash player does not support G.722.

This means it’s needed to transcode the G.722 to Flash compatible codecs.
So RSGW – [RTMP] – WebClient will not use G.722 because Flash does not support the codec.

That’s why we recommend to use Flash compatible coecs with RSGW, such as G.711 and Speex Wideband.
These codecs are natively supported by Flash and does not require any transcoding CPU expensive opeations.
