Abstract
The invention concerns a method of establishing a connection via a communications network to a called terminal (TE) which is geographically located in the area (AREA) of two or more local line networks (LNA to LNC), as well as an exchange and a service control point for carrying out this establishment of a connection. A calling terminal requests a connection to the called terminal (TE) by means of a call request (CALL(N)) which is provided with a called number (N) assigned to the called terminal (TE). To establish the connection, that of the two or more local line networks (LNA to LNC) via which the called terminal (TE) can be reached, is determined by means of a learning procedure using the called number (N).
