A caller 112 enters a number which is in service, but belonging to subscriber 114 who is a registered member of the ENSS. The call triggers an intercept at the SW 110. The SW 110 signals the CCP. The CCP 116 searches the NSHDB 108 for the called number and its subscribers, past and present, and their associated access codes. If the called number is found, the CCP 116 signals the AS 120 to request an access code from the caller. An Audio System 120 conducts a dialog with the caller to obtain the required access code, using either DTMF or voice recognition, and forwards the access code to the CCP 116. The CCP 116 compares the submitted code to the access code(s) for the current subscriber. If it matches one of these codes, the CCP 116 conferences in the number corresponding to the code, and drops off the call. | |
