The present invention relates to method of monitoring of monitor objects in a computer-integrated telecommunications environment. The method comprises, in an initial start-up phase: —upon a first-time establishment of an association between a first computing device (9) and a switching device (1) using a communication link, sending a first message (A) from the first computing device (9) to the switching device (1) to request an identification for all monitor objects that are to be monitored by the first computing device (9); —in response to the first message (A), sending a second message (B) from the switching device (1) to the first computing device (9), the second message (B) referring to a third message (C) to follow; —allocating monitor objects which the first computing device (9) is to monitor; and —sending the third message (C) from the switching device (1) to the first computing device (9), the third message (C) referring back to the second message (B), and as a single message including a list (deviceList) of all monitor objects allocated to the first computing device (9) for monitoring, wherein the list includes a parameter block for any allocated monitor object, said parameter block including information for enabling monitoring of the respective monitor object at the first computing device (9). The method may be adapted for additionally including one or more second computing devices (10) for monitoring. The invention also refers to an apparatus and a communication system adapted for implementing the method.
