Summary:PURPOSE:To attain the call operation of a called party repetitively at in- premises broadcast with a very simple operation. CONSTITUTION:A 2nd call is required when no reply comes from a called party regardless of a 1st call. In the case of making the 2nd call, a transfer party implements another specific operation (such as depression of ' ' key) in addition to the operation of a dial section of a telephone set 2B. Then a master set 1 detects the ' ' information to control a changeover section 4 thereby connecting a contact piece 40 to a terminal 4B. In this case, the master set 1 controls a recorder 3 to set it to the reproducing state. The recorder 3 is controlled by the master set 1 to reproduce the 1st called voice of the called party already recorded and the voice is outputted from speakers 5A,..., 5B via a changeover section 4. When no reply comes from the called party regardless of the 2nd call, the call tone is outputted repetitively by implementing the specific operation (such as depression of ' ' key) again. Through the operation above, the called party is called by an optional number of times till the called party is replied.
