A method of monitoring monitor objects in a computer-integrated telecommunications environment, said method comprising in an initial start-up phase: - upon a first-time establishment of an association between a first computing device and a switching device using a communication link, sending a first message from the first computing device to the switching device configured as a get switching function device message to request an identification of communication devices (3, 5, 7) connected to the switching device as monitor objects that are to be monitored by the first computing device, - in response to the first message, sending one second message from the switching device to the first computing device, the second message being an acknowledgement message configured as a get switching function devices response message, and configured to positively acknowledge receipt of the request of the first message, and the second message referring to a third message to follow by a serviceCrossReference; - allocating, by the switching device, the monitor objects which the first computing device is to monitor; and - sending the third message from the switching device to the first computing device, the third message referring back to the second message by including the serviceCrossReference again, wherein the serviceCrossReference is sent at once for all the monitor objects to be monitored, wherein the third message includes a listing of all monitor objects to be monitored by the first computing device (deviceList) that have been allocated to the first computing device for monitoring, wherein the listing includes a parameter block for any allocated monitor object, said parameter block including for each allocated monitor object including - an identifier (deviceID), - characterizing information such as a category (deviceCategory), type (deviceType) and name (deviceName), and - a monitor reference (monitorCrossReference) configured such that events involving the respective monitor object are communicated by the switching device to the first computer device. - upon a first-time establishment of an association between a first computing device and a switching device using a communication link, sending a first message from the first computing device to the switching device configured as a get switching function device message to request an identification of communication devices (3, 5, 7) connected to the switching device as monitor objects that are to be monitored by the first computing device, - in response to the first message, sending one second message from the switching device to the first computing device, the second message being an acknowledgement message configured as a get switching function devices response message, and configured to positively acknowledge receipt of the request of the first message, and the second message referring to a third message to follow by a serviceCrossReference; - allocating, by the switching device, the monitor objects which the first computing device is to monitor; and - sending the third message from the switching device to the first computing device, the third message referring back to the second message by including the serviceCrossReference again, wherein the serviceCrossReference is sent at once for all the monitor objects to be monitored, wherein the third message includes a listing of all monitor objects to be monitored by the first computing device (deviceList) that have been allocated to the first computing device for monitoring, wherein the listing includes a parameter block for any allocated monitor object, said parameter block including for each allocated monitor object including - an identifier (deviceID), - characterizing information such as a category (deviceCategory), type (deviceType) and name (deviceName), and - a monitor reference (monitorCrossReference) configured such that events involving the respective monitor object are communicated by the switching device to the first computer device.
