Avaya Voice Priority Processor Overview

The Avaya Voice Priority Processor is an Ethernet LAN device that works with access
points (APs) to provide QoS on the wireless LAN. Voice packets to and from the Avaya
Wireless IP Telephones are intercepted by the Avaya Voice Priority Processor and
encapsulated for prioritization as they are routed to and from an IP telephony server.

SpectraLink Voice Priority (SVP), QoS and Security

The Avaya Voice Priority Processor (AVPP) is an Ethernet LAN device that works with the
AP to provide quality of service QoS on the wireless LAN. Voice packets to and from the
Avaya 3641/3645 Wireless IP Telephones are intercepted by the Avaya Voice Priority
Processor and encapsulated for prioritization as they are routed to and from an IP
telephony server or gateway.
The Avaya 3641/3645 Wireless IP Telephone supports Wired Equivalent Privacy (WEP) as
defined by the 802.11 specification. Avaya offers the product with both 40-bit and 128-
bit encryption.
Avaya 3641/3645 Wireless IP Telephones support basic WMM™ as part of the 802.11e
protocol. If the AP supports WMM, the Wireless IP Telephone automatically discovers and
uses it. WMM does not replace the Avaya Voice Priority Processor as described in the
following paragraph. WMM settings must be configured on the AVPP.
Avaya 3641/3645 Wireless IP Telephones also support the 802.11i protocol including Wi-
Fi Protected Access (WPA™ and WPA2™)—PSK. Please see the Avaya Access Point
references for information about compatible systems.
The latest software versions are required to support the features described in this
document.
SpectraLink Voice Priority (SVP) is the quality of service (QoS) mechanism that is
implemented in the Wireless IP Telephone and access point (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 compatible with the IEEE 802.11b
standards.
Avaya Wireless IP Telephones support basic WMM (Wi-Fi Multimedia) if also supported by
the AP as part of the 802.11e protocol. If the AP supports WMM, the Wireless IP
Telephone automatically discovers and uses it. WMM does not replace the Avaya Voice
Priority Processor.
