I was browsing Infiltration UT mutators and came across <this>
TeamSpeakSync
TeamSpeakSync is a server-side add-on for UT and UT2004 which synchronises the players connected to a TeamSpeak server with the players in each team in-game, effectively giving each team it's own private voice chat channel. It can optionally be configured to move dead players and spectators into their own channel to prevent 'ghosting'.
I remember something about 3d voices not being added do to people bypassing the feature with 3rd party chat programs. Whether or not you would want to add 3d voice chat ingame, it would still be something that may be an interesting optional mutator for servers to use.
