Voice chat

I have already read that. But here is my next question.ňDefaultEngine.ini

 [Voice] 
 bEnabled=true
 
 [OnlineSubsystem] 
 bHasVoiceEnabled=true

In DefaultGame.ini

 [/Script/Engine.GameSession]
 bRequiresPushToTalk=false

Do I type this myself or its in there and I just change the values. Because I don’t have it in there bydefault. And also what exactly do I have to do and in which files. Thanks.
