This might be built into the game or it might be a second program such as Mumble, Ventrilo, or TeamSpeak. Two-way headsets were popular with gamers long before one saw them used for office conferencing. And gamers care much more about latency than some office flunky who hears something a second or two later than transmitted. So their codecs tend to be a lot more network-friendly, trading off quality for low latency. (Given the high bandwidth needs of video, I wonder if anyone's working on avatar-based meeting systems wherein one creates an avatar from one's photo (like Bitmoji) and uses pre-downloaded content (like video games) to construct low-bandwidth video streams?)
