ABSTRACT:
According to conventional telephone call forwarding devices, after a party at a telephone set A calls a party at a set B, a set C calls set D to forward the call, and when set D responds to set C, an alternate loop is formed between A and D. In some of said conventional devices, even when a general calling party calls set C, set B can autodial set A whose telephone number was memorized. However, nothing else can happen if set A doesn't answer the call after automatic dialing. The present invention makes it possible to store a plurality of telephone numbers of telephone sets of calling parties, A, A-1, A-2, A-3 . . . and automatically and successively to dial the stored telephone numbers of A-1, A-2, A-3 . . . even when A doesn't answer the call, so that the highly practical effectiveness can be obtained.
