ABSTRACT:
The present invention is directed to acquire a multiparty connection trunk at an office where a communication line can be used effectively when a user while communication requests the multiparty connection over different offices. In order to achieve the above mentioned object, in the present invention, an first exchange that receives a multiparty connection request designating a terminal of a third party located at a different office from a first terminal, communicating with a second terminal located at the different office or other, the first exchange generates a call setup message including, a channel number used for the communication already established, and a call reference that is different from the call reference used for the communication, and sends it to a downstream office. An second exchange receiving the call setup message determines whether or not the second terminal and/or the third party terminal is located at a office where the second exchange is located. If the called second terminal and/or the third party terminal is located at the office, the second exchange acquires a multiparty connection trunk for the multiparty connection.
