PARTNER Voice Messaging Installation and Programming
Security
The System Manager is responsible for the security of the system. As the System Manager, 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, your company is
responsible for paying for 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 messaging 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 voice messaging system:
They try to dial into a mailbox, then execute a transfer by dialing *8. Then they dial an
access code, followed by a digit string to either direct 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.
System Security Guidelines
To reduce the risk of unauthorized use of your communications and voice messaging systems, you
should:
Change the System Manager's password from the factory setting. Use a hard-to-guess value.
Advise subscribers to protect their mailboxes by changing their passwords (a four-digit
password is required) frequently. Subscribers can refer to the instructions for changing their
passwords in Using PARTNER Voice Messaging.
Monitor your call reporting system records of outgoing calls to identify possible system abuse.
You should also:
Ask users to tell you if any of the following suspicious activity occurs:
— Inability to log into PARTNER Voice Messaging.
— Lost mail messages or altered greetings.
— Inability to get an outside line.
— Series of calls with silence on the other end or with the caller hanging up.
— Sudden increase in wrong numbers.
— Caller complaints that your lines are busy.
— Callers claiming to represent the "phone" company. Ask for a callback number.
— Callers trying to obtain sensitive information or asking for assistance in placing outside or
long-distance calls. Ask for a callback number.
— Increases in internal requests for assistance in making outside calls (particularly
international calls or requests for dial tone).
Never distribute the office telephone directory to anyone outside the company.
Never discuss your telephone system's numbering plan with anyone outside your company.
