Yeah, and there's Discord, which also has group chat with history, and a decent interface. What Team Speak, Mumble, and especially Ventrilo have going for it is that they are more lightweight. However, Ventrilo has a strange latency which cannot be solved (except by moving on). Team Speak, Mumble, and Discord don't suffer from this. Also, Ventrilo cannot be self-hosted (while Team Speak and Mumble can).
