Abstract
The invention is directed at a headset for a mobile communication device having a multi-button control and is implemented with a standard headset jack. The multi-button control is decoded by a microprocessor after which an encoded signal is then transmitted from the processor to the handset. In this manner, by using the standard jack, no additional hardware is required on the handset.
