Muting a specific player

I want each client connected to the voice server to be able to choose who they hear talking or to put it another way I want each player to be able to mute other players by pushing a button next to their player name.
I can't find anything in the documentation on how this is achieved. Is it by manipulating the voicerecorder on the local instantiated network prefabs that contain the voicerecorder and voicespeaker scripts? Is it as simple as setting voicerecorder.transmit to false in the local instantiation of the network player?
