Method for controlling call setup in a telecommunication system comprising a telephone network (1), a telephone exchange (3) connected to the telephone network (1), a first subscriber line connected to the telephone exchange (3), a second subscriber line connected to the telephone exchange (3), a first telecommunication terminal (4), a second telecommunication terminal (5), an answering service (6) pertaining to the B-party. From the B-subscriber line, a function for preventing normal setup of a call from the A-subscriber line is set. The A-party is given e.g. a voice menu which the A-party uses to direct the call setup to a desired destination, preferably to the B-party's telecommunication terminal (5) or answering machine. The invention makes it possible for the B-party to set a function for his subscription that allows the A-party to make the final decision regarding the connection of a call.
