As the previous poster mentioned, that can be achieved with much simpler STUN/TURN servers provided by the vendor, that don’t take active part in sending commands etc, they just provide a basic pipe to route traffic through. Frequently they can even provide that pipe by just providing some help to link two devices so they can do direct P2P. In this environment the vendors doesn’t get to watch and inspect the content of what’s transmitted, their devices don’t phone home, and the service is trivial to restore because they’re pretty much stateless.
