Path Failure Handling

When the recovery timestamp value received is more than the previously received value, the peer restart is detected. If the timestamp is lower than the previously received value, the value is ignored and peer restart isn’t detected.

When the peer restart is detected to indicate the path failure for the peer, all the calls connected to that peer are cleared. The disconnection reason used for such calls is Sx path failure.

Sx association is also removed on detecting Sx path failure.
