Mute functionality  is a local issue. In a audio only session I can mute (voice), and the other end will suddenly stop hearing me. The same sensation if in a video session I mute my video: the other end will suddenly stop seeing me, but will remain listening my voice.

In a future, `mute()` method could acquire capability of being able to signal such intention. But I don't feel this feature should wait to that moment, as I find id cool enough, attractive.
