Abstract: In a method of setting up connections for the transfer of information in the form of calls between at least two arbitrary subscribers in a teletransmission network (1), it is detected at a subscriber interface on the basis of an identification associated with a given call whether the call is of a first type or of a second type. Then the connection is set up via a first transmission path comprising one or more exchanges (2) in case of calls of the first type, and via a second transmission path bypassing the exchange or exchanges (2) in case of calls of the second type. A detector unit (25; 41) for use in the setting up of connections in such a teletransmission network (1) comprises means (32, 33; 43) for detecting on the basis of an identification associated with a given call whether the call is of the first type or of the second type.
