Submission + - TeamSpeak, Ventrilo - Are there Free alternatives?

I'd like to help fix this issue with a more secure alternative, but I'm not so knowledgeable about the VoIP landscape. Are there any alternatives? Can something like the GNU telephony stack help — and are there tutorials on how to set it up?"
