Abstract

PURPOSE: To attain a turnback originating call even in the PBX of a direct inward dialing trunk line by executing the turnback connection of an ISDN-PBX to a call originating terminal without operating a dial from an incoming terminal.
CONSTITUTION: When a call is originated from a table 1, which is connected to an ISDN public network, having direct inward dialing trunk line and stores the extension number ob the ISDN-PBX and the extension designated number of direct inward dialing under a corresponding state, to the direct inward dialing trunk line, an address setting means 2 replaces a current extension designated number to another extension designated number of the direct inward dialing corresponding to a call originating extension. Further, a call originating sub address sent to the call originating extension is set as it is. Further, when the extension designated number of the direct inward dialing coincides with the extension number, the means 2 replaces the lower number of the pilot number of the trunk line with the call originating extension number when calling is executed for the direct inward dialing trunk line. As a call originating address, the extension designated number of the direct inward dialing is applied through the ISDN public network to the incoming terminal, and the turnback connection from the incoming terminal can be executed with the direct inward dialing trunk line.
