Voip has been working fine for weeks and then suddenly on Monday call quality sucks. I have a packet capture and trying use Wireshark to diagnose but I'm pretty new to voip troubleshooting. The reverse numbers in the screenshot seem to be pretty bad but can anybody help interpret them for me? Also the duplicate mac address errors bother me. Not sure if I did something wrong in my packet capture or if there are truly double the packets for everything. My packet capture came from port mirroring on the managed switch. The port I mirrored has the user PC and phone on the same line and that's it.
Thank you for any input you have!
