Automatic callback
In telecommunication, an automatic callback is a service feature that permits a user, when encountering a busy condition, to instruct the system to retain the called and calling numbers and to establish the call when there is an available line. Automatic callback may be implemented in the terminal, in the switching system , or shared between them. Automatic callback is not the same as camp-on.
