Preventing Toll Fraud
Toll Fraud is the unauthorized use of your telecommunications system by an unauthorized party (for example, a person who is not a corporate employee,
agent, subcontractor, or working on your company’s behalf). Be aware that there is 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
If you suspect that you are being victimized by toll fraud and you need technical assistance or support, call the Technical Service Center’s Toll Fraud
Intervention Hotline at 1.800.643.2353.
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 a person 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 could 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).
Your Responsibility for Your Company’s Telecommunications Security
The final responsibility for securing both this system and its networked equipment rests with you – an Avaya customer’s 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 Voice Priority Processor
Installation
2. Avaya Voice Priority Processor Overview
Avaya Voice Priority Processor utilizes Spectralink Voice Priority (SVP) as the Quality of Service
(QoS) mechanism that is implemented in the Wireless Telephone and AP to enhance voice quality over
the wireless network. SVP gives preference to voice packets over data packets on the wireless medium,
increasing the probability that all voice packets are transmitted efficiently and with minimum delay.
SVP is fully compliant with the IEEE 802.11 and 802.11b standards.
The Avaya Voice Priority Processor is an Ethernet LAN device that works with the AP to provide QoS
on the wireless LAN. All voice packets to and from the NetLink Wireless Telephones are intercepted
by the Avaya Voice Priority Processor and encapsulated for prioritization as they are routed to and
from the an IP server or gateway.
SVP is required for QoS because the current IEEE 802.11b wireless LAN standard provides no
mechanism for differentiating audio packets from data packets. This standard is undergoing revision to
version 802.11e to provide all the functionality of SVP in an industry standard thus ensuring high-
quality voice in a mixed client environment. Once 802.11e is ratified, SpectraLink and its 802.11
technology partners will adopt the new specification. When the 802.11e specification replaces SVP,
the Wireless Telephones can be upgraded and the Avaya Voice Priority Processor can be removed
from the system.
2.1 Avaya Voice Priority Processor Capacity
The Avaya Voice Priority Processor requires a CAT 5 cable connection between its Network port and
the Ethernet switch. The Avaya Voice Priority Processor auto-negotiates to the type of port on the
Ethernet switch and supports 10Base-T, 100Base-T, Full Duplex and Half Duplex port types. The
maximum number of calls the Avaya Voice Priority Processor is able to handle depends on LAN
factors per the following table:
10Base-T 100Base-T
