Administration of SMS history when reassining extension

The problem I ran into is assigning a new user to an unassigned extension: Old SMS history was available to the new user.

• Problem: C-Level or other VIP users may have communicated sensitive data that would otherwise be restricted to the new employee

My goal is to have a mechanism by which to purge SMS history from an extension.

• The current settings require you to gain access to the existing account and sign-in as the end-user to delete message history.

Disabling and re-enabling the Messaging does not purge the previous data unless it is manually deleted
