Service providing system cooperative with VoIP and web environments and a method therefor

摘要

In a communication system, a request is generated from a Web browser as a call attempt. A call attempt manager is booted in response to the request under the HTTP protocol. The request is turned by cooperative managers into a request under the SIP protocol, which will be processed by another call attempt manager. A response to the result of processing by the other manager is sent to a Web browser in a reverse direction on the transmission path of the request for display on the Web browser. Service proxy UA managers and the cooperative managers on both systems are brought into play in order so that the response is registered in a service proxy user agent. The result of the registration is returned to the Web system in the direction reverse to the processing result. A task is subsequently executed from the Web system to establish a call.
