Security
The System Manager is responsible for the security of the system. It is important
that you fully understand and appropriately administer this product to reduce
your risk of incurring charges that result from unauthorized use of the system.
Under the law, you, the customer are responsible for paying part or all of those
unauthorized calls.
Be aware that criminals called hackers may attempt to gain unauthorized
access to your communications system and your voice mail system. Hackers
often try to trick a company’s employees into providing them with access to an
outside line or an outside operator. They may also concentrate their activities in
two areas related to the mail system:
■
They try to dial into a mailbox, then execute a transfer by dialing [

dial or access a network operator to complete the call.
■
They try to locate unused or unprotected mailboxes and use them as
drop-off points for their own messages.
