A process that can be used to process the calling line presentation supplied to a called user following a call made by a calling user in a fixed and/or mobile communications network (for example, GSM, GPRS or UMTS in the latter case). A corresponding code for identifying an operator, such as a long-distance operator, which can be used by the called user for calling back the calling user, is identified, for example, during the registration of the user who is intended to act as the called user with a corresponding operator. This corresponding identification code is inserted automatically into the calling line presentation supplied to the called customer following the call made by the calling user. The call can be a voice call, a data call or a message, such as an SMS or MMS message. The called user is thus able to call back the calling user without having to insert the user's identification code to be used for calling back. |
