Method and system for establishing telecommunications links

A method for establishing a terminal telecommunication connection controlled by a control program with a second communication terminal, wherein a computer-telephony integration (“CTI”) service is made available to a first communication terminal by a CTI server in a CTI domain that is assigned to said CTI server, the first communication terminal being within the CTI domain and the second communication terminal being outside of the CTI domain and being connected to the CTI server via a proxy located within the CTI domain, the method comprising:

• connecting the control program to the CTI server via an intermediate functional unit;
• the intermediate functional unit signaling to the control program that the second communication terminal is a communication terminal connected to the terminal telecommunication connection instead of the proxy;
• instructing the CTI server, through the intermediate functional unit, that the CTI server is to carry out the CTI service.

A communication apparatus for establishing a telecommunication connection, comprising:

• a control device configured to connect a control program to a CTI server via an intermediate functional unit such that the intermediate functional unit signals to the control program that a second communication terminal is a communication terminal connected to a terminal telecommunication connection instead of a proxy so that the proxy connected to a first communication terminal via the terminal telecommunication connection is replaced by the second communication terminal in the terminal telecommunication connection and that the CTI server is instructable through the intermediate functional unit to carry out a CTI service.
