I had a TURN server, I just meant I didn't host it myself. But the metering showed it was never active! I kept getting a connection that succeeded through STUN, but no audio would actually come through in about 50% of WAN cases. It would always work on the LAN. Is it possible to just have a janky STUN server that negotiated a bad connection for you? Seems like a really weird failure mode. I was using Xirsys at the time as they have a mostly bare-bones setup.
