To test the actual Incident status first of all we ask the User to make a test call.
If the call fails, first check that the PrivateGSM configurations are correct and if not, fix them and close the Incident else If they are fine,
If PrivateGSM reconnects to perform the test call, then most probably we had a Temporary Network Problem issue. Let's check if the User can call other party now, if he (she) can then close the incident. If the User still can't call then check that the other device is connected and registered and if it doesn't, close the incident as "Not an issue".
If the other party is connected and registered or the test call is failed then escalate to the second level.
