That can occur if there are IPv6 candidates but the underlying system doesn’t support it. You’d need to actually look at the ICE negotiation to see what is going on.

Hi jcolp,
Thanks for the reply,

I am new in asterisk so it will be more helpful. if you can help with some example code. because those are new things for me. so a bit of example code will be more helpful.

Please help me

If you are planning to use WebRTC in any serious form you need to learn the fundamentals of that technology, including how to figure out when something is going wrong. WebRTC is not something that you can just deploy and have it work all the time. For example using Wireshark you can examine the ICE negotiation, and chrome://webrtc-internals in the browser can also provide information.
