A connection information control circuit 5 for converting a personal identification number into a name and synthesizing a voice, and receiving a caller registration application information from a subscriber.
A central processing unit 6 for controlling call processing, a main storage unit 7 for storing programs and data associated with call processing,
It is composed of a switch 8 for connecting and switching a call.

The connection information control circuit 5 of FIG. 2 is controlled by the central processing unit 6 and receives an incoming call control section 9 for receiving an incoming call transferred from the switch 8 and a personal identification number from the subscriber 1. PB signal receiving section 10, an extension number storage section 11 for storing the extension number of the call destination transferred from the incoming call control section 9, and a personal identification number storage section 12 for storing the personal identification number received by the PB signal receiving section 10. And a voice synthesizing unit 14 for collating the personal identification number received from the personal identification number storage unit 12 with the personal identification number and the registrant name registered in advance, and converting the registrant name into voice, and a PB signal receiving unit. 10, an extension number storage unit 11, and a voice synthesis unit 14, which are controlled by a call origination information receiving unit 15 that receives information of a callee (subscriber 1).

Here, it is assumed that the extension subscribers 2-1 and 2-2 are connected by a known procedure and are in a call, and the subscriber 1 sets an extension reservation for the extension subscriber 2-1. explain. Subscriber 1 dials the calling number of his private branch exchange. When the trunk circuit 4 receives a calling signal from the subscriber 1 via the public network, the central processing unit 6 detects this and sends a service setting sound to the subscriber 1 to prompt the subscriber 1 to make an additional dial. Subscriber 1 is an extension subscriber 2-
The extension number of the extension subscriber 2-1 is additionally dialed in order to connect to 1.

The central processing unit 6 detects that the extension subscriber 2-1 is busy and sends a busy tone to the subscriber 1. The subscriber 1 dials the extension subscriber 2-1 with a special number in order to register the destination, and subsequently dials his / her own personal identification number. The dial information from the subscriber 1 is transferred to the connection information control circuit 5 via the switch 8. The incoming call control unit 9 sends the transferred dial information to the PB
By connecting to the signal receiving unit 10, the PB signal receiving unit 10 stores the received personal identification number in the personal identification number storage unit 12. At the same time, the incoming call control unit 9 transfers the extension number of the extension subscriber 2-1 in the busy state to the extension number storage unit 11 and stores it.

The personal identification number storage unit 12 transfers the personal identification number received from the subscriber 1 to the registrant name identification unit 13. The registrant name identification unit 13 collates the personal identification number received from the subscriber 1 with the personal identification number registered in advance to determine whether or not the personal identification number received from the subscriber 1 is already registered. When registered, the corresponding person's name recorded corresponding to the personal identification number received is analyzed and converted into a voice code. The voice synthesizing unit 14 receives the voice code of the registrant name analyzed by the registrant name identifying unit 13, restores the voice code, and transfers the voice code to the transmission information registration receiving unit 15.

When the transfer of the voice code is completed, the central processing unit 6 controls the signal tone generator 16 to send the service setting tone to the subscriber 1 to prompt the destination registration. Subscriber 1 registers his subscriber number. The destination registration information from the subscriber 1 is received by the PB signal receiving unit 10 and is connected to and stored in the transmission information registration receiving unit 15. When the central processing unit 6 detects the end of the call of the extension subscriber 2-1 whose destination is registered, the central processing unit 6 instructs the transmission information registration receiving unit 15 to make the extension number storage unit 11
To instruct the reading of the extension number of the subscriber 2-1 and receive the extension number of the subscriber 2-1 as well as the subscriber number of the subscriber 1 and its registrant name from the transmission information registration / reception unit 15 to obtain the extension subscriber 2 -1 is called, and an audible display is made by a voice synthesis message, for example, "Calling Mr.
After that, automatic dialing is performed by the subscriber number to connect to the subscriber 1. Cancellation of extension reservation is also performed in the same manner as above.

Although the extension reservation when the called party is busy has been described above, the same operation is performed when the called party does not respond and detects the first off-hook thereafter.
