We are attempting to implement Team Media optimization using VMware Horizons and are having mixed results. In summary we can connect to Teams Meetings but cannot connect person-to-person calls.
Checking the firewall I am seeing different network ports for person-to-person calls than that of the successful person-to-meeting calls. The successful meeting calls are following documented network path and connect to udp ports 3478-3481 within the documented end-point network blocks. However the person-to-person calls attempt to connect udp ports 50000+ on address outside the defined end-point subnets.
I have found several reference documents stating the 50000+ ports (although configurable) are the source ports for media streams not the destination. I have not seen any references that 50000+ ports are destination ports.
Can anyone provide guidance on why the different types of calls are behaving differently. Additionally I would like to understand why Teams is attempting to communicate with locations not listed as any Microsoft end-point.
