Apparatus (310; 410; 510) for retrieving a website from a web server (320; 430; 520) and for establishing a communication connection, including: a send/receive interface configured to request a transmission of the website from the web server (320; 430; 520), and configured to receive the website from the web server (320; 430; 520), an output module configured to output the website to a user (305; 405; 505), wherein the output module further indicates to the user (305; 405; 505) that there is the possibility to establish the communication connection, wherein the communication connection is an audio connection or an audio/video connection or a video connection, and an input interface configured to receive an input of the user (305; 405; 505), by which the user (305; 405; 505) indicates that the communication connection is to be established, a processor module configured to generate a connection-establishment message that requests the establishment of the communication connection with a communication unit (350; 450; 550), wherein the send/receive interface is configured to send the connection-establishment message to a switching center (330; 440; 530; 1100), wherein the send/receive interface is configured to, after sending the connection-establishment message, send audio data or audio/video data or video data to the communication unit (350; 450; 550) and to receive the same from the communication unit (350; 450; 550). wherein the processor module is configured to generate the connection-establishment message used for requesting the establishment of the communication connection with the communication unit (350; 450; 550) such that the connection-establishment message does not include any information that identifies the user (305; 405; 505) of the apparatus (310; 410; 510), characterized in that the send/receive interface is configured to send to the switching center (330; 440; 530; 1100) a registration message used for requesting a registration, wherein the registration message does not include any information that identifies the user (305; 405; 505) of the apparatus (310; 410; 510), wherein the send/receive interface is configured to acquire a response message from the switching center (330; 440; 530; 1100), wherein the response message includes a registration identifier, and wherein the processor module is configured to generate the connection-establishment message used for requesting the establishment of the communication connection with the communication unit (350; 450; 550) such that the connection-establishment message includes the registration identifier. a send/receive interface configured to request a transmission of the website from the web server (320; 430; 520), and configured to receive the website from the web server (320; 430; 520), an output module configured to output the website to a user (305; 405; 505), wherein the output module further indicates to the user (305;

450; 550) and to receive the same from the communication unit (350; 450; 550). wherein the processor module is configured to generate the connection-establishment message used for requesting the establishment of the communication connection with the communication unit (350; 450; 550) such that the connection-establishment message does not include any information that identifies the user (305; 405; 505) of the apparatus (310; 410; 510), characterized in that the send/receive interface is configured to send to the switching center (330; 440; 530; 1100) a registration message used for requesting a registration, wherein the registration message does not include any information that identifies the user (305; 405; 505) of the apparatus (310; 410; 510), wherein the send/receive interface is configured to acquire a response message from the switching center (330; 440; 530; 1100), wherein the response message includes a registration identifier, and wherein the processor module is configured to generate the connection-establishment message used for requesting the establishment of the communication connection with the communication unit (350; 450; 550) such that the connection-establishment message includes the registration identifier.
