Hello, I suppose using h264 would be necessary only in SIP rooms, for all other rooms - codec which used before (h263?). It avoids any suspections about h264 issues and increses performance. I'm also going to implement switching microphone mode in the audio/video test dialog. Is there anybody who disagree with this idea?
