Abstract: A telecommunications system includes a network of coupled telecommunication exchanges (PABX1, PABX2, PABX3). At least one of the exchanges is coupled to a processor (COMP) via a so-called Computer Telephony Interface (CTI). The exchanges monitor state information for extensions (TLPH1, TLPH2, TLPH3) that are connected to the exchanges. A router routes the state information to the exchange which is coupled to the processor. That exchange transfers the state information to the processor.

Abstract: A telecommunication system including a telecommunication exchange and a controller for establishing and controlling connections between parties directly coupled to the telecommunication exchange. The controller establishes party processes associated with the parties and the party processes are established after at least two parties are directly coupled to said telecommunication exchange. The system also establishes signaling messages which are exchangeable between the party processes and indicate a changing status of one of the parties. The controller monitors the signaling messages and generates status information in response thereto while a processor receives the status information. The status information is made accessible to selected parties.
