Remote Access - Avaya Communication Manager Administrator's Manual

Remote Access

The Remote Access screen is used to implement the Remote Access feature. Remote Access
permits a caller located outside the system to access the system through the public or private
network and then use the features and services of the system.
Remote Access users can dial into the system using central office (CO), Foreign Exchange
(FX), Wide Area Telecommunications trunks (WATS), and Integrated Services Digital Network
Primary Rate Interface (ISDN-PRI) trunks. In addition, a dedicated Remote Access Direct
Inward Dialing number can be provided.

SECURITY ALERT:
Avaya designed the Remote Access feature incorporated in this product that,
SECURITY ALERT:
when properly administered by the customer, enables the customer to minimize
the ability of unauthorized persons to gain access to the network. It is the
customer's responsibility to take the appropriate steps to properly implement the
features, evaluate and administer the various restriction levels, protect access
codes and distribute them only to individuals who have been advised of the
sensitive nature of the access information. Each authorized user should be
instructed concerning the proper use and handling of access codes.
In rare instances, unauthorized individuals make connections to the
telecommunications network through use of remote access features. In such an
event, applicable tariffs require the customer pay all network charges for traffic.
Avaya cannot be responsible for such charges, and will not make any allowance
or give any credit for charges that result from unauthorized access.
To ensure the security of your system, consider the following:
Make all remote access facilities unlisted directory telephone numbers.
●
Require users to enter a Barrier Code of at least seven random digits AND an
●
Authorization Code of at least 13 random digits to make network calls.
Make Authorization Codes nonconsecutive (random) and change them, at least, quarterly.
●
Deactivate Authorization Codes immediately if the user leaves the company or changes

assignments.
Assign the minimum level of calling permissions required to each Authorization Code.
●
Block off-hours and weekend remote access calling, when possible. Use Alternative
●
Facility Restriction Levels, if available.
Use a voice recording, warble tone, or no tone and avoid use of a dial tone as a prompt
●
when the remote access unit answers.
Assign the lowest possible FRL to only allow calls internal to Avaya Communication
