An ETSI standard contains a definition to the effect that the number to be transmitted to a subscriber line in a telephone exchange system to identify the other party of a call may be a number stored in the subscriber data for the other party of a number given from the other party's subscriber line. The invention relates to a procedure for the transmission of numbers to a subscriber line in accordance with the user's preferences. In other words, the invention allows the user to decide himself/herself whether the other party's number to be transmitted for presentation to the user's subscriber line is the number stored in the subscriber data for the other party, the number given from the other party's subscriber line, or both.
