Hi,
do you have the possibility to do a 1:1 call between two devices, that are in the same network?
The media path is different when it comes to a 1:1 call compared to a conference call. In the scenario where you do a 1:1 call with a device that is in the same network as yours, the media data will be exchanged directly between the two peers without any other components involved (like Teams Relays, Firewall, etc.). Would be good to know if this scenario is working for you.
Greets,
Markus
