Abstract
In a switching system, the subscriber stations of which are linked to a switching centers of a first communication network, which are connected to each other through a second communication network, such as the internet, by means of transition devices, with which separate control devices are associated to control the connection traffic as a function of control and/or signaling information. A communication connection is established to a subscriber station to be called, the availability of which has changed from one switching center to another switching center, by first setting up a signaling connection to the switching center at which the subscriber station to be called was hitherto available, whereupon a communication connection is established using the control and/or signaling information specifying the changed availability of the subscriber station to be called directly to the other switching center at which the subscriber station to be called is now available, via the transition device connecting this switching center to the second communication network.
