CAUTION:
Your Voice Mail system permits callers to leave verbal messages for
system users or gain access to the back-up position in an emergency
as well as create and distribute voice messages among system users.
The Voice Mail system, through proper administration, can help you
reduce the risk of unauthorized persons gaining access to the network.
However, phone numbers and authorization codes can be
compromised when overheard in a public location, are lost through
theft of a wallet or purse containing access information, or through
carelessness (writing codes on a piece of paper and improperly
discarding them). Additionally, hackers may use a computer to dial an
access code and then publish the information to other hackers.
Substantial charges can accumulate quickly. It is your responsibility to
take appropriate steps to implement the features properly, evaluate
and administer the various restriction levels, protect and carefully
distribute access codes.
Under applicable tariffs, you will be responsible for payment of toll
charges. AT& T cannot be responsible for such charges and will not
make any allowance or give any credit resulting from unauthorized
access.
