Voice messaging systems

7-46 Issue 9 May 2003

Take the following preventative measures to limit the risk of unauthorized use of

the Automated Attendant feature by hackers:

■ Do not use automated attendant selector codes for automatic route

selection (ARS) codes or pooled facility codes.

■ Assign all unused automated attendant selector codes to zero, so that

attempts to dial these will be routed to the system operator or General

Mailbox.

■ If RCF is required, coordinate with your Avaya Account Team or authorized

dealer to verify the type of central office facility used for RCF. If a

ground-start line/trunk, or a loop-start line/trunk and central office reliable

disconnect can be ensured, then nothing else need be done.

NOTE:

In many cases these will be loop-start lines/trunks without reliable

disconnect. The local telephone company will need to be involved to

change the facilities used for RCF to ground start lines/trunks.

Usually a charge applies for this change. Also, hardware and

software changes may need to be made in the MERLIN LEGEND

Communications System. The Automated Attendant feature merely

accesses the RCF feature in the MERLIN LEGEND Communications

System. Without these changes being made, this feature is highly

susceptible to toll fraud. The same preventative measures must be

taken if the RCF feature is active for MERLIN LEGEND

Communications System extensions, whether or not accessed by an

automated attendant menu.

Protecting passwords

For the MERLIN MAIL and MERLIN MAIL-ML voice messaging systems,

passwords can be up to four digits. For the MERLIN MAIL R3 and MERLIN

LEGEND Mail Voice Messaging System, passwords can be up to 15 digits. See

‘‘Administration / maintenance access’’ on page 4-4

and ‘‘General security

measures’’ on page 4-8 for secure password guidelines. See Chapter 14 for

information on how to change passwords.

Security tips

The MERLIN MAIL, MERLIN MAIL-ML, MERLIN MAIL R3, and MERLIN LEGEND

Mail voice messaging systems, through proper administration, can help you

reduce the risk of unauthorized persons gaining access to the network. However,

phone numbers and authorization codes can be compromised when overheard in

a public location, lost through theft of a wallet or purse containing access

information, or when treated carelessly (writing codes on a piece of paper and

improperly discarding them).
