Stop hacker getting through VM?

[nalaikki]

Hi! We have the Nortel Norstar system and recently started having a problem with someone hacking into our phone lines through our voicemail system and placing long distance calls. I am aware that there is a way to make sure that the voicemail boxes are set so that they do no allow outbound calls. I simply don't know where this control is. How can I access this and set it so that outbound calls are restricted?

Any help would be greatly appreciated!
I'm not trained on this system. Basically, the company who installed the system for us has a bunch of pretty disgruntled workers who offer no help so I've had to read and learn the system on my own so I'm sorry if this is really low level stuff!--Thanks!

From one of my previous posts:

The easiest way to see how voicemail is configured to redirect callers is to use the reporting feature in NVM 4.0.
The NVM should have shipped with a documentation CD.
On the CD is an application you may install called Norstar Voicemail Manager.
If you install this you may manage the NVM through the NVM manager software via the default IP address of the NVM.
192.168.110.10
There is a reporting application there.
You can view the system config and each mailbox individually to see if things are being forwarded.
You can also edit class of service values using this tool to deny OPN and outbound transfer.
Creating a filter will not restrict the mail from completing long distance conference transfers. You MUST edit the COS values using Norstar Voice Mail Manager!
NVM 4.1 has a feature enhancement to allow COS edits through a telephone, however only NVM manager will generate the required reports to identify this problem QUICKLY.
Norstar Voice Mail Manager is free and will easily identify the mailbox or AA in question if you suspect the mail.
Filters are a good way to deny long distance to internal telephone users.
Also make sure you change all default passwords on the mail and KSU, especially for the system admin mailbox and general delivery. NVM 4.0 also includes a password expiry feature to force a password change every 90 days. This may have been turned off. Use NVM manager to confirm and re-instate this rule if you are being defrauded.
