Abstract

The invention concerns a method of establishing a connection for a communications network (KN2) in which two or more terminals (TE2 to TE7) are assigned to a user group (UG), as well as an exchange and a service computer to carry out this method. A call request is directed by a calling terminal (TE1) to a called terminal (TE5) of the communications network (KN2) which is assigned to the user group (UG). Upon a request from the other terminal or from one of the other terminals (TE2, TE3, TE4, TE6) of user group (UG), a connection (CON) is established between the calling terminal (TE1) and the requesting terminal (TE4). Before the connection between the calling terminal (TE1) and the requesting terminal (TE4) i15 has been established, data (DAT, DAT′) which determine the calling terminal (TE1) are sent to the other terminal or at least to one of the other terminals (TE2, TE3, TE4, TE6) of user group (UG).
