Recipient’s name
confirmation Octel Unified Messenger confirms the name of the recipient before
sending a voice message from one subscriber to another. This feature
makes it possible for sender of voice messages to ensure that their
messages are delivered to the intended destination.
Disconnecting
callers who enter
incorrect passwords If a caller enters an incorrect password to a subscriber’s account, Octel
Unified Messenger informs the caller of the error, and requests entry of
the correct password. The caller is offered another opportunity for two
reasons:
n The caller might have pressed keys quickly, inadvertently missing
digits.
n The caller may have recently changed his or her password and
accidentally entered the old password.
Octel Unified Messenger can be configured to disconnect when a
threshold of between one to three attempts has been met. If a caller does
not enter the correct password in the allowed number of attempts, the
caller is automatically disconnected. This feature prevents unauthorized
users from trying various numbers repeatedly in order to discover a
password.
Handling callers
who make too many
errors Octel Unified Messenger has the capability to disconnect or transfer
callers who make too many errors while trying to navigate through the
system. The number of errors - from 0 to 9 errors - can be configured on a
system-wide basis.
Monitoring system
usage reports Octel Unified Messenger provides two standard reports that allow the
administrator to monitor the system for potential misuse. These can be
generated using the Reporting Tool application.
n The Port Statistics report shows the number of calls coming into
the ports. Substantial activity occurring at unusual times of the
day can be an indicator of unauthorized system usage.
n The Login Failures report records information about unsuccessful
telephone logins due to an incorrect password or mailbox number
being entered. Numerous login failures may indicate
unauthorized users trying to access Octel Unified Messenger.
Other security
precautions Additional security measures can be implemented on PBX or Centrex
systems.
Access restrictions can be imposed by limiting access to the lines used by
Octel Unified Messenger for call processing through toll restriction. Long
distance carriers also have security services available to help control
unauthorized users. They can monitor normal usage and provide
immediate notification of unusually high long-distance call activity.
Organizations should contact their long distance carrier for more
information about these services.
