In iOS , Peer network connection lost information is not getting notified in other peer

In iOS , when a successful video connection is established, if one of the device lost network connection, the other device is not getting notified. In this scenario, peer left information is not getting hit in any of the delegates instead remote view just blacks out.

Any help will be appreciated.

No files or tests are named. Start by reproducing the iOS video session with one peer losing network connectivity, then trace the peer-connection delegate callbacks and remote-view state; done means the remaining peer receives peer-left information through the expected delegate instead of only showing a black view.
