- Are you using direct routing?
- If yes, what SBC are you using?
- If using direct routing, are you using media bypass?
- Is it all inbound calls drop?
- Is it an immediate drop, or is there a delay of a few seconds?
- Do you hear any audio on either side?

Do you know if you're using media bypass? What operating system? I'm assuming Windows? I see you mentioned that you're on the same network as others that do not have the same problem, so that should in theory eliminate a network firewall, what about firewall on the workstation? Can you disable it and retest?
There are different port requirements between the Windows client, and the browser client. Teams should handle the firewall stuffs automatically, but it might still be an issue.
