Microsoft canonical address format for telephone numbers〔(Microsoft Technet: Canonical address format for phone numbers )〕 defines a universal formatting recognized by the Windows Server Telephony API (TAPI). This format derives from the E.123 format by authorizing the embedding of the area codes, delimited by parentheses, inside the E.123 international format. This flexible addition to the E.123 international format makes the Microsoft format the de facto standard used to display telephone numbers that can be easily understood both by national and internal users. ==Microsoft canonical format description== The canonical address format is: +Country/RegionCode (AreaCode) SubscriberNumber and is formed with the following components and rules: * The leading plus (+) indicates the beginning of a canonical telephone address format. * The country or region code which contains one or more digits from 0 through 9. * A space must be used after the country or region code. * Parentheses are delimiting the optional area code which contains one or more digits from 0 through 9. * A space must be used after the area code. * The subscriber number contains one or more digits from 0 to 9, formatting characters, or the dialing control characters: A a B b C c D d P p T t W w * # ! @ $ ?. * Formatting characters allowed to make the subscriber number easier to read are spaces, periods, and dashes. 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「Microsoft telephone number format」の詳細全文を読む スポンサード リンク
