Issues with teams calls

Hello,

we have issues with teams calls and suspect that the sophos XG 550 (latest official firmware) is causing this.

Examining one of the clients I found these entries. 

What is/could be an invalid packet in this context?

Regards,
Bernd

    Not in this case. For VPN software we use split tunnel in general.

    High & reserved bandwith. The only thing could be are maybe spikes that fly below the granularity of PRTG network monitoring. Maybe wrong priority of Teams packets.

    Sometimes in the past we saw incoming packets blocked for some time. This resulted in almost similar behaviour  but was more widespread among clients.
