摘要： In an incoming call service by which an extension can be directly called when a call comes in from another office, a dedicated terminal for selecting an extension to which the incoming call is connected is installed to enable the user to select it as desired, thereby increasing usage of call incoming lines for effective use. An exchange which connects an incoming call from another office directly to an extension, an input device for accepting specification of an extension corresponding to a specific incoming call, and a controller which includes a definition device for defining the correspondence between the specific incoming call and extension are provided. Upon receipt of an incoming call, the exchange connects the call to its corresponding extension in response to the correspondence defined in the definition device.
