In the course of an application involving real-time notification of a client by a telephone switching system, a connection between the client and a server is opened. Notification messages transmitted from the telephone switching system to the server are adjusted and sent to the client in the format of a programming language code executable by the client's browser. The programming language codes are subsequently executed by the browser, whereby the respective notification messages are displayed at the client. For transmission of the notification messages from the server to the browser, as streaming method such as HTTP streaming is use so that the connection remains open while notification messages are to be sent. The presented method can be based on standardized protocols, entails little protocol overhead and allows for facile treatment of security issues.
