Network data stream
To log the network data stream, a network log (*.pcap) can be recorded. This log can be evaluated (e.g.,with Wireshark/Ethereal), for instance, to determine the cause of malfunctions.
Important: Note the following legal notes prior to recording a network data stream.The recorded network data stream may contain the following components:
•Data streams of other computers in the network
•Connection data sets with destination, source, and time information of a telecommunication connection
•The spoken word of both ends of a telecommunication connection
•Configuration data of the PBX and connected phones, as well as the corresponding PINs and passwords
Important: Before any recording, all participants in the telecommunication connection must be informed that these contents will be recorded and must also be informed who will use the recorded data.Important: If you want to make the recorded data available to your specialised dealer or to the manufacturer for error analysis, you must make sure that the legal requirements are fulfilled.Proceed as follows:
