For example, this is used when other endpoints of the same user have registered and the registrar decides to unregister the oldest endpoint. The ms-diagnostics-public ErrorId for this event is 4140. For more information, see [MS-OCER] section 7.

deregistered;event=rejected: This is used by the registrar if the user is disabled for SIP communication. For example, this can happen if the administrator decides to lock the user's account.

The ms-diagnostics-public ErrorId for this event is 4141. For more information, see [MS-OCER] section 7.
