Control of a telephone switching system over a digital information network

摘要

Disclosed is a mechanism to integrate a telephone switching system (23) into a wide area (WAN) or local area (LAN) computer network, where in particular, a telephone switching center is controlled by a server computer (22) utilizing a Hypertext Transfer Protocol (HTTP), which is connected to a WorldWideWeb (WWW) network. Known computer telephone integration (CTI) solutions are integrated on a network server and thus have the drawback that due to the various different operating system platforms, in particular in the area of Personal Computers or Workstations, an interface has to be adapted to each client's platform. It is therefore proposed to provide, between a HTTP server (22) and the switching system (23), a control program (20) which enables control of a CTI application by the HTTP server (22), in order to integrate the functionality of a switching network into the HTTP server (22). The proposed application (20) provides an interface which uses a Universal Resource Locator (URL) specifying high level communicating functions which are independent of the respective interface (21) to the switching system or the CTI server.
