==Multiple servers==
We operate multiple servers. These are configured using DNS and SRV records as well as A and AAAA records to ensure devices register and send calls via the currently active servers. We can change which servers are active from time to time.

Some devices will stick to one server after an initial DNS look up, so we may reject a registration if we are taking that server out of action, but we aim to do that after DNS has already changed. Such devices will then re-check DNS and connect to the current servers.
