Abstract
To establish a toll-free communication connection between a calling terminal (TE ) which is connected to a first communications network (KN ), and a called terminal, a connection request with a toll-free universal call number (IFN) is transmitted as a called number to the first communications network (KN ). In this case the toll-free universal call number (IFN) is provided by a service unit (SERV) of a second communications network (KN ). The first communications network (KN ) recognizes the connection request as one with a toll-free universal call number and an inquiry is then sent by the first communications network (KN ) to this service unit (SERV) of the second communications network (KN ). From the toll-free universal call number this service unit (SERV) then determines a toll-free local call number (LFN) of the first communications network (KN ), and returns same to the first communications network (KN ). The first communications network (KN ) subsequently establishes the requested connection in accordance with this determined toll-free local call number (LFN).
