Every sight is different so you will need to do what suits the customer.
KSU/BCM:
-Disable DISA and/or change COS password to something more secure.
-Setup restriction filters and have them applied to voice mail ports/DN's.
-Setup restriction filters and have them applied to lines and/or setup COS passwords to bypass restrictions.
-Disable Allow Redirect option for all sets.
Restiction example- Restrict 0 for overseas, 1 for local long distance, 900 for billing.
Voice Mail
-NAM's and Call Pilot (Voice Messaging) run the Toll Fraud Patches, for BCM's make sure your upgraded to latest patches.
-Delete all unused mailboxes
-Have ALL users change mailbox passwords to 6 or 8 digit non-trivial passwords, including Genreal Delivery and System manager mailboxes.
-Disable Outbound Transfer/Dial/Pool Access in admin programming (COS) for each mailbox.
-Disable the "enable external initialization" feature in COS
-Setup lockup mailbox after so many unsucessfull password attempts

Turn off external transfers in CP class of service. And make sure that users of VM are using good passwords.
