Abstract: A method for managing an incoming call in a communication terminal is described, the incoming call having an associated call identifier. The method can comprise checking the routing of an outgoing call to the call identifier associated with the incoming call, and classifying the incoming call on the basis of the result of the checking of the routing, the incoming call being classified as a malicious incoming call if the checking of the routing reveals that the outgoing call is not able to be routed. The method can be used, for example, to detect malicious calls or spam.

Abstract: 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.

Abstract: In the course of an application involving real-time notification of a client (PC(CC)) by a telephone switching system (TS) a connection between the client (PC(CC)) and a server (CtC) is opened. Notification messages transmitted from the telephone switching system (TS) to the server (CtC) are adjusted and sent to the client (PC(CC)) 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 (PC(CC)). For transmission of the notification messages from the server (CtC) to the browser (PC(CC)) a streaming method such as HTTP streaming is used so that the connection remains open while notification messages are to be sent. The present method can be based on standardised protocols, entails little protocol overhead and allows for a facile treatment of security issues.
