Caller ID - Type II Caller ID

Type II Caller ID

In 1995, Bellcore released another type of modulation similar to Bell 202 in which it became possible to transmit caller ID information and even provide call-disposition options while the user was already on the telephone. This service became known in some markets as call waiting ID, or (when it was combined with call-disposition options), Call Waiting Deluxe; it is technically referred to as Analog Display Services Interface. "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 (not a new feature)
• 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.
