Note:
The latest wireless telephone and Handset Administration Tool software versions are
required to support the features described in this document. See Chapter 3: Software
License and Protocol Management.
WLAN Quality of Service
You may obtain the WLAN Quality of Service (QoS) using one of three available
mechanisms: SpectraLink Voice Priority (SVP), Wi-Fi Standard QoS, or Cisco
Compatible Extensions (CCX) version 4. However, you cannot mix these QoS modes
within the same WLAN. Therefore, all Wireless Telephones on the network must have
the same QoS setting.
SVP
SpectraLink Voice Priority (SVP) is a proprietary method of WLAN QoS, developed by
Polycom, to ensure enterprise-grade voice quality, battery life and call capacity for
Wireless Telephones. SVP requires the use of the SVP Server, which is an Ethernet
LAN device that works in conjunction with Wi-Fi APs to ensure QoS over the WLAN.
Voice packets to and from the Wireless Telephones are tunneled through the SVP
Server to ensure voice prioritization as they are routed between the handset and SIP call
server. See the Avaya SVP Server Administration Guide for detailed information about
this device.
Wi-Fi Standard QoS
Avaya 3641/3645/6120/6140 IP Wireless Handsets support WMM, WMM Power Save
and WMM Admission Control - all QoS standards from the Wi-Fi Alliance based on IEEE
802.11e. The combination of these three standards provides enterprise-class QoS in
terms of voice quality, battery life and call capacity. The WLAN must also support and
enable each of these QoS mechanisms in order to ensure they are utilized. This option
does not require the SVP Server.
CCXv4
The CCX program requires WLAN client devices operating on Cisco APs to use a
defined set of industry standards and Cisco-specific features. The Avaya
3641/3645/6120/6140 IP Wireless Handset has been certified by Cisco as CCXv4
compliant. When you select the CCXv4 operating mode on the handset, it automatically
initiates the required set of Cisco-specific and industry standard QoS mechanisms. This
option does not require the SVP Server.
