Abstract

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.

Claims

1. A method of providing selective call-forwarding from a calling line via a called subscriber line, said called subscriber line having a procured telephone company service to thereafter connect said calling line via said called line to a third telephone line via said procured service, said called subscriber line further connected to an automatic answering and storage apparatus operative to detect ringing of said line to go off-hook and connect to said calling line, comprising the steps of:

placing a first message on said connected line requesting a caller on said calling line to enter an authorization code, and,

responding to said authorization code to determine if same is a subscriber owner code, and,

upon determination that said authorization code is a valid subscriber owner code, accessing said automatic answering and storage apparatus to cause the same to receive programming data indicative of a different third telephone line, or;

upon determination that said authorization code is not a subscriber owner code, responding to said authorization code to determine if said authorization code is a valid preferred-caller forward authorization code, and,

upon determination that said authorization code is a valid preferred-caller forwarding authorization code, making connection to said third telephone line via said procured service as controlled by said automatic answering and storage apparatus, or;

if said authorization code is not validated in either alternative step above described, placing a second message on said connected called line requesting said calling line party to leave an incoming message on said automatic answering and storage apparatus, and storing said incoming

7. The method according to claim 1, 2, 3, 4, 5, or 6 wherein said procured service is a telephone company 3-way-calling service, and wherein, when said call-forwarding is effected, said called subscriber line acts as the connecting interface between said calling line and said third telephone line throughout the full duration of the forwarding connection.

8. The method according to claim 1, 2, 3, 4, 5, or 6 wherein said procured service is a telephone company call-forwarding service, and wherein, when said call-forwarding is to be effected, said connection via said procured service is effected comprising the steps of:

3. A method of providing selective call-forwarding from a calling line via a called subscriber line, said called subscriber line having a procured telephone company service to thereafter connect said calling line via said called line to a third telephone line via said procured service, said called subscriber line further connected to an automatic answering and storage apparatus operative to detect ringing of said line to go off-hook and connect to said calling line, wherein a caller possessing a preferred-caller forwarding authorization code may elect to be either forwarded to said third telephone line or, alternatively, to record a message on said automatic answering and storage apparatus, comprising the steps of:

responding to an authorization code on said connected line to determine if same is a subscriber owner code, and,

upon determination that said authorization code is a valid subscriber owner code, accessing said automatic answering and storage apparatus to cause the same to receive programming data indicative of a different third telephone line, or;

upon determination that said authorization code is not a subscriber owner code, responding to said authorization code to determine if said authorization code is valid preferred-caller forwarding authorization code and,

upon determination that said authorization code is a valid preferred-caller forwarding authorization code, making connection to said third telephone line via said procured service as controlled by said automatic answering and storage apparatus, or;

if said authorization code is not validated in either alternative step above described, storing an incoming message on said automatic answering and storage apparatus.

4. A method of providing selective call-forwarding from a calling line via a called subscriber line, said called subscriber line having a procured telephone company service to thereafter connect said calling line via said called line to a third telephone line via said procured service, said called subscriber line further connected to an automatic answering and storage apparatus operative to detect ringing of said line to go off-hook and connect to said calling line, comprising the steps of:

placing a first message on said connected line requesting a caller on said calling line to enter an authorization code, and,
