Abstract
Techniques for providing audio services to multiple devices are described. For instance, connections between a hands-free unit and multiple wireless devices are established. The connections are themselves used to establish active communication channels, such as active audio communication channels, between the hands-free unit and the wireless devices, such as during a phone call. Upon establishment of an active communication channel with one of the wireless devices, the connections to the other wireless devices are disconnected—and/or additional connections refused—for the duration of the active communication channel. Furthermore, a routing module in various embodiments permits multiple hands-free units to route active communication channels to each other depending on user location.
