PURPOSE:To call out a message operator only with a calling, by providing a memory during the message set corresponding to extension. CONSTITUTION:When a message request is produced to an extension SUB-A having a message, a message operator SUB-B operates a message key KEY corresponding to the SUB-A and the corresponding message visual display device LMP illuminates via a message controller MSC. At the same time, a flag during message is set to an address of the MSM corresponding to the SUB-A. With this state, if the SUB-A is called, a central controller CC reads out the content corresponding to the called SUB-A from the MSM and no transmission connection is made since the message flag is set and the intra-offic connection is made by taking the SUB-B as a called extension. |
