Security
Because the AMIS Analog Networking and/or Message Delivery features use the
switch’s analog lines to transmit messages, verify that the class of restriction
(COR) assigned to the local system’s voice ports supports outcalling, or these
features will not work. For example, to protect against possible toll fraud, the local
system’s voice ports might be restricted from accessing 2-way or outgoing trunk
groups. The COR for the voice mail system might need to be altered to allow the
AMIS Analog Networking, Message Delivery, and Outcalling features to work.
However, if left completely unrestricted, the AMIS Analog Networking and/or
Message Delivery features could allow local voice mail users to send messages
to any valid telephone number worldwide. Consequently, the system
administrator must use judgment when administering the AMIS Analog
Networking and/or Message Delivery features. For example:
In order to minimize exposure to unauthorized long-distance calls, the
AMIS Analog Networking and Message Delivery features should be
restricted to sending messages to remote machines or telephone
numbers located in specific calling areas or at the specific destinations
needed to conduct business.
Additionally, the system administrator can use the
Message Sending
Restrictions
feature to limit the use of the AMIS Analog Networking and/or
Message Delivery features to only those subscribers who have a need to
use it. The Message Sending Restrictions feature can also be used to limit
AMIS Analog Networking and/or Message Delivery calls to specified
remote machines (numbers) or user communities. It may be overridden for
specific subscribers if needed. Refer to the feature descriptions manual
for your voice mail system for more information on the Message Sending
Restrictions feature.
