Abstract: Disclosed is a method for establishing a telecommunications link (C1, C2, C3) for a user to whom a first communications terminal (D1) is allocated. According to said method, an allocation information is made available to a control program (100, 22) running on a CTI server (20) for establishing the telecommunications link (C1, C2, C3), in which information a first allocation (72, 92) is defined for the first communications terminal (D1) as specified by the user, said first allocation defining an allocation of a second communications terminal (D3, D4) to the first communications terminal (D1). The telecommunications link (C1, C2, C3) is established by the control program (100, 22) in accordance with the first allocation, using the second communications terminal (D3, D4) instead of the first communications terminal (D1).

The first signalling Server which has been informed or a second signalling Server which has been informed by this first signalling Server recognizes that the call is intended to be made with a particular quality of Service and sets up a communication link between the first telephony terminal and the second telephony terminal, which link corresponds to this quality of Service.

Abstract: Described is a method for channel management on one or more digital signal processors. The method distinguishes itself by the fact that channel management occurs at any time based on a current load utilization of each digital signal processor, taking into account an actual load requirement of each channel and a maximum total performance capacity of each digital signal processor. The invention also relates to a device for carrying out the method.

Abstract: The invention relates to a method for establishing a telecommunications link (C1, C2, C3), controlled by a control program (28), with a second communications terminal (D1), according to which a CTI service is made available to the first communications terminal (36) by a CTI server (20) in a CTI domain allocated to said CTI server (20), and the second communications terminal (D1) is located outside the CTI domain and by way of a proxy (Trk2) situated within the CTI domain is linked to the CTI server (20). The control program (28) is linked to the CTI server (20) by way of an intermediate functional unit (30, 32). The intermediate functional unit (30, 32) signals to the control program (28) that the second communications terminal (D1) instead of the proxy (Trk2) is linked into the established telecommunications link (C1, C2, C3) as the telecommunications terminal.
