Yes an no. If you can't trust the network you're running on, you could get around this by tunneling via Tor. Tox itself makes direct connections to friends, to exchange encrypted messages, so while they can see when you send packets, and to what IP. They can't know what's in those messages. The trade off is, they'd need to be able to MITM your network. There's no servers they can capture, to learn this information no matter where you are.
