Abstract
A method is provided for preventing the transmission of unsolicited phone calls. The telephone number corresponding to the source of the phone call is first compared with a reject list and with an approved list to determine whether the call should be transmitted to the user. If the telephone number corresponding to the source of the phone call is not on either list, a registration procedure is carried out. Upon being successfully registered, the phone call is transmitted to the user and the source is added to the approved list.
