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.
