Change position of Voice Call interface to top or sides of the phone.

Anyway we could see the buttons and the tab that control the calls to be placed to the top or sides of the phone? This way people dont accidentally hit the very sensitive back, home or active application buttons? Or accidentally end a call or deafen? For example. When you get into a voice chat in a server the buttons to mute, deafen, end call and silence are all near the home buttons on android devices which means you can easily accidentally hit the buttons on your device which will accidentally make you switch apps or you can accidentally end call or mute yourself. This could be easily fixed if the menu was placed elsewhere other than the bottom of the screen.
