<p>No additional steps are considered to be necessary as most telecom service providers already offer a range of services that can help to reduce the need to answer unwanted calls. This includes BT's ‘Choose to Refuse’ service, which allows consumers to block numbers by specifying numbers they do not want to receive calls from; Caller Display that enables a consumer to ignore calls that withhold their number; and Anonymous Call Rejection that allows a consumer to block incoming calls that withhold their number. A range of other call blocking systems are also commercially available that can help to block unwanted calls.</p>
