发明名称 APPARATUS AND METHODS FOR SELECTIVELY FORWARDING TELEPHONE CALLS
摘要 A selective call-forwarding method and apparatus utilizes telephone company facilities whereby a calling party will only be forwarded if a preferred calling code number is entered by the calling party. Upon receipt of a preferred calling code, a detector operates to detect and validate the code. Once the code is detected and validated, the apparatus proceeds to implement a connection to a third phone based on the automatic implementation of telephone company operating procedures to make the connection and, thereby, to selectively connect a preferred calling party to a remote telephone whereby the preferred party can communicate with the subscriber who has the procured service.
