RE: Voice Quality issue - Question to PCAP
Attaching a PC on the phone's switch port ist the most pragmatic way to do this, I understand that. Yet, if you are not onsite and the phone in question is 1h by car away, that is not really a good solution.

Perhaps the folks from Yealink could introduce some kind of "remote PCAP"?

For example, if I need to do a remote capture on a linux box and display in Wireshark on my machine, I would do something like this:
ssh someuser@ sudo tcpdump -iany -U -s0 -w - 'not port 22' | wireshark-gtk -k -i -

Would be nice if yealink phones would allow something similar. Of course those phones might not (yet) have tcpdump installed and make it available via ssh pipe.. On the other hand, why not make the PCAP output available as a stream on a port, instead just write to a local file?

Another way is shown on AVM Routers. When I do a PCAP trace there (i.e. http://fritz.box/html/capture.html), the file is directly written to the local disk of the machine I am connecting from with the browser. So, no disk space is used on the router. I guess that might be even more simple to program into the phone firmware..
