Notify other participants in call when a participant lost internet during the call

When a participant lost internet connection during the call, Other participants in call doesn’t know the that a participant lost connection from the call. If there are more than 2 participants in call, it’s fine, Because others two would be communicating. But when we have 2 participants only in call, It creates problem. Other participants is talking in call without knowing that remote participant has lost connection.

How to notify other users that a participant lost internet & trying to reconnect during the call?
