ABSTRACT:
A method and apparatus is provided for setting up a voice conference call or sharing audio content. The method includes the steps of providing an audio mixer that receives an audio input from each of at least three audio interfaces of the conference call, mixes the audio inputs and provides an equalized audio output to each of the at least three audio interfaces, providing a first local wireless interface between a first audio interface of the at least three audio interfaces and a first headset, providing a second local interface between a second audio interface of the at least three audio interfaces and a second headset and coupling a third audio interface of the at least three audio interfaces to a third headset through a base station of a cellular network, wherein the communication paths to the first, second and third persons are all different.
