Does anyone know how to do the TURN portion of Ice4j? I've managed to code it so that it works when the phone is on WiFi, but not when its on the mobile network.
I'm sending agent info via TCP and then building the connection manually instead of using a signalling process. The TCP connection already works fine, so I don't think its the TCP issue. Maybe I'm building the agent wrong?
I know that you're supposed to use a TURN server if STUN doesn't work, and I provided a large list of public TURN servers, but I might be missing something. Maybe the packets aren't being sent out properly?
