In order to capture issues on a device, it is possible to start a trace directly from the Yealink device itself. Traces from made from the device itself shows in many cases more detailed information about the possible causes then when a trace is made from the Kwebbl servers.
There are two different traces:

After the trace is performed, the file can be opened in 'Wireshark'
