An H.323 or SIP connection is set up from a source network (LAN 1 ) via at least one packet-oriented transit network (WAN 1 , WAN 2 ) to a connection destination (EG 2 ) which is external to the source network. The connection is set up via gateway devices (GW 1 , . . . , GW 4 ) which are cascaded between networks and respectively manage only access to gateway devices and communication devices which are logically directly adjacent. In this context, H.323 connection setup signaling (SET 1 , . . . , SET 4 ) is conveyed, using logical address information ( 030 - 222 ) or sections thereof ( 030, 030 - 2 ), from gateway device to gateway device until it reaches the connection destination (EG 2 ).
