Microsoft Teams voice Breaking in UTM

Hi All Experts here, this is my first time handling with Sophos UTM and have a lots of stuff to learn. 

Recently we implemented Microsoft Teams, but 1 of my location (Sophos UTM SG105) when using it the voice is breaking when connecting to another oversea region, on my UTM i dont have any Anto-DOSFlood and Anti Port Scan turn on or enabled, the only thing that is turn on is the IPS status at the Global tab. 

As for the Web filtering, i have include 0365 exceptions like. is 1 whole long list.  

^https?://([A-Za-z0-9.-]*\.)?teams.microsoft.com/

I have read other threads, that going to logs and repoorting to look for clues, but pardon me, i am not sure which logs should i dig into and what entries (Host / IP) should i look out for? 

Anyone has any idea?

  • Hi and welcome to the UTM Community!

    Since Philipp's how-to has all screen shots in English, you should be able to follow it.  Here is the English version of the Microsoft document he links to.

  • Hi BAlfson & jprusch

    Thanks for your reply. i have added the Exceptions on the IPS exception settings. 

    but like i have mentioned, i don't have any TCP / UDP flood Protection turn on, so will by adding the exception still help? 

    Only Global IPS turn on. 

    additionally, i have also add 1 firewall rules hopefully somehow it able to help on this,

    Thanks in advance.
