A wireless user terminal operates in a mode that is selected based on an indication of the orientation of the wireless user terminal from a gravitational sensor in the wireless user terminal. When the wireless user terminal is in a first orientation, the wireless user terminal operates in a speakerphone mode. When the wireless user terminal is in a second orientation, the wireless user terminal operates in a handset mode. The mode of operation of the wireless user terminal transitions based on movement of the wireless user terminal from the first orientation to the second orientation. For example, when the wireless user terminal placed in a horizontal orientation, one of the speakerphone modes is selected. When the user picks up the wireless user terminal, the wireless user terminal transitions to handset mode. In a personal speakerphone mode, the volume to a handset speaker in the wireless user terminal is increased so that a call may be carried on without holding the wireless user terminal near the user's ear and mouth. In a conference speakerphone mode, the wireless user terminal transmits/receives audio signals to/from an external speaker and external microphone.

1. A communications device providing handset mode operation and speakerphone mode operation, said communications device comprising:a gravitational sensor that senses first and second directions of a gravitational field relative to the communications device in respective first and second orientations of the communications device relative to the gravitational field; and a processor, responsive to the gravitational sensor, that selects speakerphone mode of operation for the communications device when the gravitational sensor senses the first direction of the gravitational field relative to the communications device in the first orientation of the communications device relative to the gravitational field and that selects handset mode of operation for the communications device when the gravitational sensor senses the second direction of the gravitational field relative to the communications device in the second orientation of the communications device relative to the gravitational field, wherein the processor determines that a difference between the first and second orientations of the communications device is greater than a programmable threshold.
