THE INVENTIVE IDEA IS TO SET UP BY PARTS A FORWARDED CALL USING SERVICES OF A CLOSED USER GROUP LEG-SPECIFICALLY. HEREBY THE USER GROUP DATA DEFINED BY THE SUBSCRIBERS FOR THE LEG IN QUESTION CAN BE USED FOR EACH LEG. THE USER GROUP DATA DEFINED BY THE CALLING SUBSCRIBER IS USED IN THAT LEG OF THE CALL WHICH IS BETWEEN THE CALLING SUBSCRIBER AND THE CALL FORWARDING POINT. USER GROUP DATA DEFINED BY THE CALLED SUBSCRIBER WHO FORWARDED THE CALL IS USED BETWEEN THE FORWARDING POINT AND THE SUBSCRIBER WHO IS THE FORWARDING TARGET.(FIG. 9)
