A priority call is a telephone call that has been assigned some enhanced level of priority for processing by a telecommunications network such that it may be expected to achieve precedence over other traffic. In a given network, there may be several levels of priority. ''Priority call'', and ''priority ring'' are also brand names of calling features which give a distinctive ring to calls from telephone numbers chosen by the subscriber and which require a subscription from their local telephone company. To set up priority call, one dials *61 and follows the instructions. To disable priority call, one dials *81. == See also == * Enhanced 911 * Message precedence 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「Priority call」の詳細全文を読む スポンサード リンク
