Abstract

The present invention provides a wireless headset that anchors voice communications or calls to the wireless headset. This wireless headset includes wireless interface(s), and earpiece, a microphone, processing module, and a user interface. The wireless interface(s) wirelessly couples the wireless headset to a base unit via a wireless personal area network (WPAN). The earpiece renders inbound portions of the service calls audible while the microphone is operable to produce the outbound portion of the call. Both the earpiece and microphone are communicatively coupled to the wireless interface(s). The processing module also coupled to the wireless interface(s) allows the wireless headset to initiate call functions between the wireless headset and a servicing network made available through the base unit, service a call and call control functions, and anchor the call to the wireless headset. The user interface in conjunction with the processing module allows the wireless headset to initiate commands and/or call control functions based upon user input.
