Abstract

PURPOSE:To avoid the necessity of re-calling, by automatic connection to called telephone set, after guiding the new number in audio message, when the number before the changed number is dialed from the calling telephone set. CONSTITUTION:When the telephone set SUB1 makes call, it is connected to the outgoing register trunk ORT via the path (1) of the communication network NW and transmitted to the central control unit CC via the scanning unit SCN. The central control unit CC collates the content of the main memory unit MM based on the dial information and it knows the number is changed with the content of the memory unit MN, the telephone set SUB1 is reconnected to the talkie trunk TKT, the message of changed number is transmitted from the talkie TKE, and after that, the central control unit CC connects the called telephone set SUB2 to the callout signal trunk RGT via the path (3a) of the communication line network NW. On the other hand, the caller telephone set SUB1 is connected to the callout tone trunk RBT via the path (3b). Next, the telephone sets SUB1, SUB2 are connected to the intra-office trunk IOT via the paths (4b), (4c) respectively to enable communication.
