PURPOSE:To allow a caller to know in advance a call to be subjected to absence transfer by transmitting a message that the connected call is subjected to absence transfer to the caller. CONSTITUTION:When a subscriber A hooks off and dials the number of a subscriber B, an outgoing register 8 receives and counts it and transfer the information to a central controller 2. The controller 2 collates this information with the storage content of a data memory device 3 and when it is detected that the number is registered for absence transfer, a talkie trunk 4 is acquired to connect the subscriber A and the trunk 4 and a message of absence transfer is transmitted to the subscriber A. Then the controller 2 reads information of subscriber C being destination of absence transfer from the memory device 3 and connects the subscribers A and C. Thus, the subscriber A makes a call after the connection destination is the subscriber C. |
