Environment:

OS name: Ubuntu
OS version: 22.04.2LTS
Architecture: Linux em04 5.15.0-73-generic #80-Ubuntu SMP Mon May 15 15:18:26 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
nprobe version/revision: nProbe v.10.3.230629 for x86_64-pc-linux-gnu, Built with nDPI 4.7.0-4188-86e89b4e

What happened:

★Both Microsoft Teams and Zoom have this problem.

The nprobe's RTP plugin shows blank values for the MOS and R_FACTOR like attached file.
bug report2ntop.xlsx

In my understandings If the "L7 PROTO" is "91.125" it should be reported with the MOS and R_FACTOR but it is still blank.
This attached data is when Microsoft Teams meeting was ongoing.

Could you share the condition details when the nprobe wrote the MOS and R_FACTOR value?

How did you reproduce it?
If you do Microsoft Teams or Zoom you could reproduce this one.

Debug Information:
Kindly refer to the attached file.

This is traffic on port 443, not RTP so it's normal that MOS and R_FACTOR are not there. You need to capture UDP traffic that is STUN,RTP etc.
