Filed: 1987-11-20
Abstract: PURPOSE:To grasp charging information for each extension by informing the charging information of a transfer sender extension to the operator every time an extension giving a trunk line call is changed by the transfer operation. CONSTITUTION:When an extension STA 1 transfers a trunk line call to an extension STA 2, a central controller CC calls the extension STA 2 by the known method, sets a channel P3 in the network NW, connects an office line trunk COT and the extension STA 2 and releases the channel P2 to transfer the trunk line call from the extension STA 1 to the extension STA 2. Then a charging information notice processing unit MNTC extracts an extension number N1 and charging information CI 1 for each extension stored in a charging control memory CHGD, stores them in an operator charging information notice memory MET and informs it to the operator OP. Thus, since the charging information is noticed to the operator for each line communicated with the trunk line call, the charging information for each extension is grasped accurately.
