PURPOSE:To simplify the response operation of a party to be transferred by collating the extension number of the party to be transferred with extension number of a party to be transferred stored by the dial operation of a response personnel in advance and connecting the transfer of a trunk line incoming call when the numbers are coincident. CONSTITUTION:When the extension A and a trunk line trunk (COT) are in service as shown in Figure, the extension A reserves a trunk line incoming call and hooks off so that the extension A is to be responded by the extension B. Then, the extension A catches an outgoing register trunk (ORT) and after a call tone is listened to, a trunk line incoming call reserving special number (X or Y) is dialed, and the extension number of the extension B is dialed succeedingly. The trunk line incoming call is reserved completely by the operation of dial. The extension number of the extension B is read by two paths shown in Fig., and the number read out is collated with the extension number of the extension B analyzed in advance and when they are coincident, the extension B is connected to the trunk line (COT) reserved and the call between both the parties is attained. |
