Avaya 3641/3645 Wireless IP Telephone Overview
The Avaya 3641/3645 Wireless IP Telephone is a Wi-Fi handset for workplace IP
telephone systems. The Wireless IP Telephone operates over an 802.11a/b/g/n wireless
Ethernet LAN providing users a wireless voice over IP (VoIP) extension. By seamlessly
integrating with an Avaya Aura™ Communication Manager, Wireless IP Telephone users
are provided with high-quality mobile voice communications throughout the workplace.
The Wireless IP Telephone gives users the freedom to roam throughout the workplace
while providing users with all the features and functionality of an IP desk phone.
The Avaya 3641/3645 Wireless IP Telephone provides a wireless extension to the Avaya
Aura™ Communication Manager. The Wireless IP Telephones reside on the wireless LAN
with other wireless devices using direct-sequence spread spectrum (DSSS) radio
technology. The handset radio transmits and receives packets at up to 54Mb/s using
802.11a/b/g technology.
A Wireless IP Telephone must be administered on the Avaya Aura™ Communication
Manager for the specific features and lines to be accessed by the Wireless IP Telephone.
After the handset is registered, it receives its configuration information from the Avaya
Aura™ Communication Manager.
The Wireless IP Telephone may be administered on the Avaya IP Office Server but certain
functionality described in this document will not be available. The Call Logs and
corresponding Redial features are replaced by a simple Redial function that lists recently
dialed numbers. See section 4.1

1.1
WLAN Quality of Service (QoS)
Quality of Service is provided by using SpectraLink Voice Priority (SVP), Wi-Fi Standard
QoS or Cisco Compatible Extensions (CCX) version 4. These QoS modes can not be mixed
within the same WLAN; all Wireless IP Telephones on the network must have the same
QoS setting.
SVP
SpectraLink Voice Priority is a proprietary method of WLAN QoS, developed by
Polycom, to ensure enterprise-grade voice quality, battery life and call capacity for
SpectraLink Wireless IP Telephones. SVP requires the Avaya Voice Priority Processor
(AVPP) 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 IP
Telephones are forwarded through the AVPP Server to ensure voice prioritization as
they are routed between the handset and an IP telephony server. See the
SpectraLink
SVP Server: Administration Guide within IP Environments
document for detailed
information about this device.
Wi-Fi Standard QoS
Avaya 3641/3645 Wireless IP Telephone 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
