Environment

• Ant Media Server version: 2.12.0
• Browser name and version: Chrome
  
  

Steps to reproduce

1. We have configured the circle app on our ANT server.
2. Create a conference room through the above circle application and let 3+ guys join in the call.
3. Call is connected properly and all 3+ participant are able to see and hear each other.
4. Now one of the 3 participants leave the call and joins back again. (Browser refresh)
5. The left participant get connected in the call properly and able to see other participant. But the other 3 participant get ice connection callback.
6. The ice connection state changes from new to checking and then connected. But for one user the ice connection state switches to disconnect.
7. To reproduce this you may need to do 3 to 4 attempts with above step: 3 and step: 4 steps.

Expected behavior

Whenever new user joins the conference, the ice connection connectivity should remain connected consistently.

Actual behavior

Joining of new user, make the connection unstable for other users. The UI get freeze and does not recover from the state.
