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.
To reduce the risk of unauthorized access through your voice mail system,
please observe the following procedures:
Employees who have voice mailboxes should be required to use
the passwords to protect their mailboxes,
— Have them use random sequence passwords.
— Impress upon them the importance of keeping their passwords
a secret.
— Encourage them to change their passwords regularly.
The administrator should remove any unneeded voice mailboxes
from the system immediately.
AUDIX Voice Power has the ability to limit transfers to subscribers
only. You are strongly urged to limit transfers in this manner.
Use the Hybrid/PBX or Key system administration capability to do
the following:
— Block direct access to outgoing lines and force the use of
account codes/authorization codes.
— Disallow trunk-to-trunk transfer unless required.
— Assign toll restriction levels to all AUDIX Voice Power ports or
other voice mail ports.
— If you do not need to use the Outcalling feature, completely
restrict the outward calling capability of the AUDIX Voice Power
ports. Use voice mail application features to do this.
