Call issues using VMware Media Optimization

Question

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.

Hello MatthewDVA,

Good day to you and hope you are doing well.

Based on your requirement have search but couldn’t found any particular information for the same. Generally for Teams access this port required. We recommend to kindly post your question to Microsoft Q & A community site to check if they can provide you some information or suggestion for your requirement. At this point, your kind understanding and co-operation will be highly appreciated.

Thank you so much for your precious time. Stay safe and be happy with good health.
