ABSTRACT:
A method for the establishment of a connection from a first network to a second network. During call set-up, a part (N3) of the call number assigned to a subscriber (B) is transmitted from a first network (PUBNET) to a second network (PRNET) using a method different from that used to signal address information. In particular, the dialing of an IN service transports a part of the call number, in the area intended for the ISDN subaddress, to a private branch exchange (EX4) associated with the called subscriber (B).
