Often DTMF responses are needed while on- line with a handheld telephony device (cellular or cordless phone). In order to enter these responses the device must be removed from the ear, moved within the line of sight and DTMF keypad digits pressed. Due to the movement and rapid response of the device connected at the far end, the next selection on the menu is often missed. To avoid this, a handheld phone could provide a removable keypad to allow the user to keep the earpiece and microphone stationary while entering DTMF key- pad responses.
