Hi, AFAIK, ICE is used to detect as many ways as possible to send media stream to the other client. If it can't find, it will use TURN protocol to determine media relay proxy.

Can we benefit from ICE if we're in symmetric NAT? -- Khoa Pham HCMC University of Science Faculty of Information Technology -------------- next part -------------- An HTML attachment was scrubbed...
