A method and apparatus perform call control by obtaining initial biometric information of ears of a user of a handheld audio device; detecting a change in the biometric information of the ears of the user; determining a position and motion of the handheld audio device by analyzing the detected change in biometric information; and performing call control based on the determined position and motion. Further, the method and apparatus perform a first call control operation in response to the determined motion and position if the handheld audio device is communicating with a first endpoint and a second call control operation if communicating with a second endpoint. In addition, the method and apparatus change an internal call control operation of a handheld audio device by determining motion and a position of the handheld audio device. Also, the method and apparatus control internal operations of an endpoint by determining motion and position of the handheld audio device without terminating communication with the handheld audio device wherein the endpoint is one of a voice messaging system, conferencing system, or telephone operator.
