SECURITY ALERT:
The Find Me feature can be misused to commit toll fraud. When a
call triggers Find Me, the MAS generates an outgoing call to a list
of telephone numbers that subscribers provide, hence making the
system vulnerable to toll fraud. The Find Me feature is enabled by
means of a class-of-service (COS) setting. Administrators are
advised to enable Find Me, by the relevant COS, for only those
subscribers that truly require this method of notification.
Administrators can also take additional security measures such
as assigning a restrictive PBX COS to the PBX ports used to
make the outcall, or requiring account codes or authorization
codes. For more information on toll fraud, see ‘Modular
Messaging and Security’ on CD-ROM Avaya Modular Messaging

.
Using Find Me Subscribers set up rules for using Find Me on the Assistant page in
Subscriber Options. Find Me rules are created by selecting values in the
following rule description:
“When anyone phones me when schedule [schedule name] is active call
phone numbers in [phone list].”
An example rule might be:
“When anyone phones me when schedule [weekend schedule] is active
call phone numbers in [personal list].”
Find Me rules are created using Subscriber Options. They can be enabled
or disabled using Subscriber Options or from the Modular Messaging
Aria TUI.
Find Me in offline
mode
Find Me information (such as Find Me rules, schedules, and telephone
lists) uses the message store to keep the master copy, and is cached on
each MAS.
When a call comes in that requires Find Me, the MAS checks to see if the
cache is up to date. If not, the MAS reads the updated information from
the message store, updates the cache and then applies the rule.
When a subscriber changes a Find Me rule, the cache on an MAS is not
updated until the MAS handles a call for the subscriber. If the message
store cannot be accessed when that call arrives, the MAS cannot reach the
message store, and hence cannot check to see if it has the most recent
Find Me information. In such a case, the MAS will use the last available
information that is cached on the MAS, to control Find Me.
