Communicator Phone Edition device logs remain on the device until they are uploaded to the Logs folder unless the device encounters an error that causes it to shut down. In that case, the device first attempts to upload its CE Logs, as well as any Watson data. As long as the device is running normally, Communicator Phone Edition log files must be manually uploaded from the device, as described later in this topic.

You can configure a RoundTable device to automatically upload log files on a schedule, as described in Appendix D: Configuring RoundTable to use Device Update Service. If you want to manually upload a RoundTable log file, you can do so by using the procedure in this topic.

Device logs have a .clg file extension and can be read by extracting the log file contents to a text file by using the ReadLog.exe tool that is included with Microsoft Windows Embedded CE . For details about the location of log files, see Log File Types and Locations. For details about reading and analyzing device logs, see the documentation for your UC device.


To view a device log, you must be logged on as a member of the RTCUniversalServerAdmins group or with an account that has equivalent privileges.
