A telephone exchange connects a plurality of telephone terminals through a communication network that transmits voice packet, and allows the plurality of telephone terminals to communicate with each other. The telephone exchange includes: a storage unit, a controller, and a transfer unit. The storage unit stores a group table representing a correspondence between a plurality of extension groups into which the telephone terminals are classified and the telephone terminals belonging to the extension groups. The controller, when a connection request to one of the extension groups occurs, refers to the group table and performs connection control for the telephone terminals in the corresponding extension group. The transfer unit transfers voice packets sent from the requester to all of the telephone terminals that belongs to the corresponding extension group through the communication network. |
