摘要：
The invention relates to a method for establishing a telephone connection between subscribers of a first telephone net (P) to subscribers of a second telephone net (T1, T2, T3). A calling private branch exchange (N1, N2) of the first telephone net communicates a subscriber's number to a central control unit (C). Said central control unit determines the private branch exchange (N1, N2) from which the second telephone net is accessed. Subsequently, the connection to the subscriber of the second telephone net is established.
