SECURITY ALERT:
The Call Me feature can be misused to commit toll fraud. When a
message triggers Call 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 Call Me feature is
enabled by means of a class-of-service (COS) setting.
Administrators are advised to enable Call 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 Release 2 Documentation, 11-300121

Notes:
! The Call Me Server and MWI Server must be installed on the
same MAS and must be set up to share the same Mailbox
Monitoring service.
! The Call Me Server, MAS units, and e-mail server (Microsoft
Exchange and IBM Lotus Domino message stores), must have
their system clocks synchronized using a time service.
Using Call Me Subscribers set up a rule for using Call Me on the Assistant page in
Subscriber Options. A Call Me rule is created by selecting values in the
following rule description:
“When [schedule] is active, if [message type] with [importance], from
[sender] have arrived, call telephone numbers in [phone list] within
[minutes] and then every [interval].”
An example rule might be:
“When schedule [commute time] is active, if [new voice messages] with
[high importance], from [John Smith] have arrived, call phone numbers in
[my personal list] within [15 minutes], and then every [20 minutes].”
Call Me rules are created using Subscriber Options. The rules can be
enabled or disabled using Subscriber Option or from the Modular
Messaging telephone user interfaces (TUIs).
When answering a Call Me call, subscribers are presented with a common
Call Me interface. This interface provides options for receiving the call,
blocking the call, and logging in to their mailboxes. The options of the
Call Me interface are the same for all subscribers, regardless of the TUI
assigned to them.
Call Me in Offline
Mode
Outcalls from the Call Me feature are not made while either the message
store or the MAS on which the Call Me server resides is not accessible.
These calls may be made when both are operational again.
