Abstract
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 (T , T , T ). A calling private branch exchange (N , N ) 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 (N , N ) from which the second telephone net is accessed. Subsequently, the connection to the subscriber of the second telephone net is established.
