To be clear for Overwatch only console party voice chat is peer to peer, not the in game Overwatch voice chat. This means you have to join a PSN party to reveal your IP. This is also true for Xbox One. Subtle but important distinction, don’t want to scare people away from talking in Overwatch but players should avoid console parties with players they do not trust.
