: ''The codes described are relevant only to the NANP telephone system. A similar feature is used in European ISDN networks, which is mandated by the European Telecommunication Regulation in the Directive on Privacy and Electronic Communications, cf. Wikipedia (de).'' Anonymous call rejection is a landline calling feature which screens out calls from callers who have blocked their Caller ID information. Anonymous Call Rejection is based on caller ID (not automatic number identification or ANI). It is often free with caller ID on landlines. Incoming callers with caller-ID blocking enabled, when ringing a line with anonymous call rejection, will hear a message stating that this line does not accept calls from callers who block their number. Callers who have blocked their Caller ID information will then hear a recording instructing them not to block their Caller ID when calling that line. This feature is normally included with Caller ID, but may be available separately from your local telephone company. The ACR feature is not available in all areas. It is not available from most cellphone services with caller ID, such as Sprint, T-Mobile USA or AT&T. Verizon Wireless does provide this service, but ACR prevents dialing a feature code or successfully calling customer service. Verizon Wireless does not currently provide blocked or anonymous call rejection, but customers may block up to five specific numbers at (MyVerizon ).〔(【引用サイトリンク】title=Block/Unblock Number Verizon Wireless )〕 ==How to use== Where available in North America, one may enter *77 to enable, or *87 to disable, anonymous call rejection. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Anonymous call rejection」の詳細全文を読む スポンサード リンク
