Call Waiting Deluxe is the Bellcore (now Telcordia Technologies) term for Type II caller ID with Disposition Options. This CLASS-based POTS-telephone calling feature works by combining the services of call waiting with caller ID but also introduces an "options" feature that, in conjunction with certain screen-based telephones, or other capable equipment, gives a telephone user the option to * Switch: Place the current call on hold to take the second call (not a new feature) * Hang-up: Disconnect the current call and take the second call * Please Hold: Send the caller either a custom or telephone-company-generated voice message asking the caller to hold * Forward to Voice Mail: Send the incoming caller to the recipient’s voice mail service. * Join: Add the incoming caller to the existing conversation. For more information, please see the Analog Display Services Interface article. 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「Call Waiting Deluxe」の詳細全文を読む スポンサード リンク
