an unauthorized party (for example, a person who is not a corporate
employee, agent, subcontractor, or is not working on your company's
behalf). Be aware that there may be a risk of toll fraud associated with your
system and that, if toll fraud occurs, it can result in substantial additional
charges for your telecommunications services.
Avaya Fraud Intervention

Providing Telecommunications Security
Telecommunications security (of voice, data, and/or video
communications) is the prevention of any type of intrusion to (that is, either
unauthorized or malicious access to or use of) your company's
telecommunications equipment by some party.
Your company's “telecommunications equipment” includes both this Avaya
product and any other voice/data/video equipment that could be accessed
via this Avaya product (that is, “networked equipment”).
An “outside party” is anyone who is not a corporate employee, agent,
subcontractor, or is not working on your company's behalf. Whereas, a
“malicious party” is anyone (including someone who may be otherwise
authorized) who accesses your telecommunications equipment with either
malicious or mischievous intent.
Such intrusions may be either to/through synchronous (time-multiplexed
and/or circuit-based), or asynchronous (character-, message-, or
packet-based) equipment, or interfaces for reasons of:
• Utilization (of capabilities special to the accessed equipment)
• Theft (such as, of intellectual property, financial assets, or toll
facility access)
• Eavesdropping (privacy invasions to humans)
• Mischief (troubling, but apparently innocuous, tampering)
• Harm (such as harmful tampering, data loss or alteration,
regardless of motive or intent)
Be aware that there may be a risk of unauthorized intrusions associated
with your system and/or its networked equipment. Also realize that, if such
an intrusion should occur, it could result in a variety of losses to your
company (including but not limited to, human/data privacy, intellectual
property, material assets, financial resources, labor costs, and/or legal
costs).
Responsibility for Your Company’s Telecommunications Security
The final responsibility for securing both this system and its networked
equipment rests with you - Avaya’s customer system administrator, your
telecommunications peers, and your managers. Base the fulfillment of your
responsibility on acquired knowledge and resources from a variety of
sources including but not limited to:
• Installation documents
• System administration documents
• Security documents
• Hardware-/software-based security tools
• Shared information between you and your peers
• Telecommunications security experts
To prevent intrusions to your telecommunications equipment, you and your
peers should carefully program and configure:
• Your Avaya-provided telecommunications systems and their
interfaces
• Your Avaya-provided software applications, as well as their
underlying hardware/software platforms and interfaces
• Any other equipment networked to your Avaya products

Call Appearance and Call Identification Displays
By default, the 2420 telephone has eight call appearance/feature buttons per screen page.
When Call Center mode is enabled, 12 call appearance/feature buttons appear on the first two
pages of the Home Screen.
Starting with the first button in the upper left corner of the 2420 telephone and going down, the
display identifies the buttons in the left column. These buttons are considered call appearance/
feature buttons 1 through 4. On the display, these buttons have the default labels a, b, c, etc.,
where a represents call appearance/feature button 1. The buttons in the right column run from 5
through 8. If Call Center mode is enabled, call appearance/feature buttons 17 through 20 are
identified by default labels q, r, s, and t. These call appearance/feature buttons appear along
the bottom of the screen with abbreviated labels.
When you receive or make calls, the available call identification information is displayed where
the date and time appear when the telephone is idle. For example, when you dial an extension,
that number is shown and then replaced by the called party’s name and extension. The call
processing system provides the call identification information that is associated with an
extension. When you receive a call from another extension, the caller’s name appears. When
you receive a call from outside the system, the calling number (if available), “OUTSIDE CALL,”
or a trunk identifier appears.
The Home Screen
One call appearance is underlined at all times. When a call arrives at the 2420 telephone, the
bell icon blinks on the corresponding call appearance. After you answer the call, the active call
