Description (partial)

Symptom:
In case of session recovery failure the IMS sessions will be hung both in MS and in IMS core. This may results in not receiving the incoming calls till IMS re-registration is done. The SR/ICSR audit needs to be handled such a way that UE will be informed about the call failure so that it will trigger the re-registration.

Conditions:
Audit failures during switchover
