A contact center media server for aurally positioning participants of a contact center transaction at aural positions designated by a contact center agent. The media server includes a communications interface coupled to a controller and adapted to interface with a plurality of voice paths. Each of the voice paths is associated with one of a plurality of participants in a contact center transaction. A three-dimensional (3D) spatializer engine is coupled to the controller and can receive incoming voice signals received over voice paths and corresponding aural position data. The 3D spatializer engine processes the incoming voice signals and generates outgoing voice signals that include signal characteristics that aurally position the first outgoing voice signals at an aural position with respect to the contact center agent indicated by the aural position data.
