Call quality issues with Teams

L'UNICA SOLUZIONE PER ME  è STATA QUELLA DELLA DISABILITAZIONE Protezione contro il flooding UDP

Ciao Luca and welcome to the UTM Community!

It would be interesting to see an extract of the Intrusion Prevention log when Teams, Zoom or WebEx is active.  That might tell us what Exception was missing.

PS Thanks for posting in Italiano - reminded me of the time when I lived in Paris and traveled all over France, Germany and northern Italia to participate in scherma competitions. 

ITALIANO: HO IMPOSTATO 3 DIVERSE MODALITA' DI ECCEZIONI PERCHE' QUALSIASI COSA FACEVO NEI LOG

                  RISULTA SEMPRE UN BLOCCO CON IP APPARTENTI A MICROSOFT DIVERSI DA QUELLI INDICATI .

IN ENGLISH:

I SET 3 DIFFERENT EXCEPTION MODES BECAUSE EVERYTHING I DID IN THE LOGS

THERE IS ALWAYS A LOCK WITH IP APARTMENTS IN MICROSOFT DIFFERENT FROM THOSE INDICATED.

IN ENGLISH:

I SET 3 DIFFERENT EXCEPTION MODES BECAUSE EVERYTHING I DID IN THE LOGS

IT ALWAYS RESULTS A BLOCK WITH IP BELONGING TO MICROSOFT DIFFERENT FROM THOSE INDICATED.

I solved it as follows (see attachment):

The networks are:

1) 13.107.64.0/18
2) 52.112.0.0/14
3) 52.120.0.0/14

The service group included:
1) TCP/UDP 3478:3481
2) TCP/UDP 50000:50059

HTTP & HTTPS I just took it fresh today because these ports are also used

But I have to admit that I am not 100% satisfied yet. We still have quality problems again and again

so the problems are still there ...

YOU GIVE ME CONFIRMATION BY WRITING THIS:

UDP flooding disabled was the only solution for me

Disable UDP flooding in general or only for certain networks?

Have you looked at my IPS rule again? It differs from hers a little. For example, you make an AND condition and not an OR condition.

Did you also create a firewall rule?

I would like to try again to recreate the right exceptions and the right firewall rules.

can you tell me better and in detail the exceptions in IPS and the firewall rules you have set ??

any rules or exceptions I have set have failed.

that's why I had to disable UDP flooding

please

Everything comes out of my picture & text

Guys, unless we look at an excerpt from the Intrusion Prevention log when you're having a quality issue, we can't even guess what the issue might be.

do you mean me?

Ihr alle, Ludo 

Logs and pictures are the best way to chase down an issue.

But Bob, I already made screenshots available for Luca :-)

No one has posted an extract of the Intrusion Prevention log when the problem is occurring.
