Strange teams network traffic to 192.168.1.x IPs on our DMZ subnet
When doing firewall audits (Palo Alto) we used the following query to investigate very strange teams behavior sometimes talking to certain IP addresses on our DMZ which in some cases don't even exist...
Do you have direct routing in MS Teams? Or use a hosted SBC? 50,000 port range is pretty common for folks to use for media ports on SBCs, and if you have Direct Routing or a hosted SBC, you may have "media bypass" enabled, which would make the clients attempt to talk to the SBC directly. With no response from those addresses, it'll fall back to using the media transport services in MS Teams instead.
- We do not have any voice , or teams to phone system features. When I go to Voice > Direct Routing there's just a local route there
Priority 1 dialed number pattern: ^(\+1[0-9]{10})$
