<p>The method involves initiating call from a computer-based dialog system (IVR) to a subscriber terminal equipment (TE) e.g. wireless telephone. Information of the dialog system is output into the equipment. An authentication signal is transmitted to the dialog system in response to the information by the equipment, where reception of the authentication signal in the dialog system initiates a note of connection data that is stored in a call database (CDR). The data is transmitted to the database and added with tariff information in the database. An independent claim is also included for a computer program with program code for executing a telephone call and invoice method.</p> |
