Last-call return, automatic recall, or (on PBX and centrex service) camp-on, is a telecommunication feature offered by telephony service providers to subscribers to provide the subscriber with the telephone number, and sometimes the time, of the last caller. The service may also offer the facility to place a call to the calling party.
The general public tends to refer to the service by the telephone feature code, the telephone number it has in their country; for example, in North America, this is *69, while in the UK, it is called 1471. The New York Times described Call Return in 1992 as a new service.[1] It can be paid for per-call or subscribed to monthly.[1]
