Have anyone seen this problem? What would be cost of this problem? Thanks in advance.

Explanation: A connection was established and immediately dropped before completing registration. Incomplete registration may indicate a device is rehoming in the middle of registration. The alarm could also indicate a device misconfiguration, database error, or an illegal/unknown device trying to attempt a connection.
Recommended Action: No action is required if this event was issued as a result of a normal device rehome..

You have a device (eg a phone or an ATA) that is trying to register but it is either not configured on the server or it is configured wrong so it gets denied.
