Abstract: When a specific numerical sequence and the SIP telephone number are entered on a telephone of any subscriber connection of switching equipment that is allocated to the communications network, the numerical sequence is evaluated in such a way that a first message containing the telephone number of the subscriber connection and the entered SIP telephone number is transmitted to a media gateway controller of the communications network. The controller transmits a second message containing the transmitted telephone number of the subscriber connection and the SIP telephone number to a SIP registrar, which saves the telephone number as the new current telephone number for calls to the SIP telephone number. Calls for the SIP telephone number are then re-directed to the current telephone number from the location service database.
