The system also is used as an unpublished telephone number service to enable a caller to place a message that is relayed to a subscriber. The subscriber, based on the caller's message, then can return the call to communicate with the caller. Further, the system may be used to enable a subscribing caller to place calls to persons having caller identification telephone equipment capable of identifying the telephone numbers of callers.Other References
