Chapter Two: Avaya 3641/3645/6120/6140 IP
Wireless Handset Overview
The Avaya 3641/3645/6120/6140 IP Wireless Handsets are Wi-Fi handsets for
workplace telephone systems. The handsets operate over a VIEW-certified
802.11a/b/g/n wireless LAN (WLAN) providing users a wireless extension of the SIP call
server. By seamlessly integrating into a SIP environment, the system provides high-
quality mobile voice communication to the wireless telephone users throughout the
workplace. The system gives users the freedom to roam throughout the workplace while
providing many of the features and functionality of a wired SIP desk phone.
Note:
The Avaya 3641/3645/6120/6140 IP Wireless Handsets do not provide 802.11n support
in their Admin menu structure. However, Polycom VIEW certifies the APs running in ‘n’
mode. When the APs use ‘n’ mode, the handset registers as a ‘b’ client and negotiates a
lower rate for its own traffic. This has the effect of slowing down the overall network
speed, but this is no different than any legacy ‘b’ client co-existing on an ‘n’ network.
Consult the VIEW Certified AP Guide for more information.
In a SIP environment, each handset may have up to six sets of credentials to identify
itself as belonging to a particular user. The Avaya Aura® configuration establishes the
maximum calls per line. .
Changing the software from H.323/CCMS or UNIStim
to SIP
The Avaya 3641/3645 IP Wireless Handsets default software is the CCMS protocol
software. The Avaya 6120/6140 IP Wireless Handset default software is the UNIStim
protocol software. You will need to change the license to the SIP software in the Admin
menu. See the minimum configuration instructions in Chapter 5 for exact instructions.
Note:
Only Avaya 6120/6140 IP Wireless Handsets manufactured after August 2010
are capable of loading SIP software. The manufacturing date can be seen on
the label in the battery compartment.
The default admin password for each protocol is as follows:
Avaya SIP 27238 (CRAFT)
CCMS 123456

UNIStim 123456
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.

Avaya 3641/3645 IP Wireless Handset Overview
Avaya 3641/3645/6120/6140 IP Wireless Handset SIP Administration Guide June 2012 11
WLAN security
The handsets support the following security methods:
WPA2 Enterprise
The handsets support WPA2 Enterprise, as defined by the Wi-Fi Alliance. The 802.11i
standard based WPA2 provides government-grade security by implementing the
Advanced Encryption Standard (AES) encryption algorithm. The Enterprise version of
WPA2 uses 802.1X authentication, which is a port-based network access control
mechanism using dynamic encryption keys to protect data privacy. The handsets
support two 802.1X authentication methods: EAP-FAST and PEAPv0/MSCHAPv2. Both
of these methods require a RADIUS authentication server on the network and accessible
to the phone. See the System Components section for tested models. For additional
details, see Chapter Three: SIP Integration Factors.
Normal 802.1X authentication requires the client to renegotiate its key with the
authentication server on every AP handoff. This renegotiation is a time-consuming
process that negatively affects time-sensitive applications such as voice. Fast AP
handoff methods allow for the part of the key derived from the server to be cached in the
wireless network, thereby shortening the time to renegotiate a secure handoff. The
Wireless Telephone supports two fast AP handoff techniques, Cisco Client Key
Management (CCKM) (only available on Cisco APs) or Opportunistic Key Caching
(OKC). You must configure one of these methods for support on the WLAN to ensure
proper performance of the handset.
WPA and WPA2 Personal
The handset supports WPA and WPA2 Personal, as defined by the Wi-Fi Alliance.
Based on the 802.11i standard, WPA2 provides government-grade security by
implementing the Advanced Encryption Standard (AES) encryption algorithm. WPA is
based on a draft version of the 802.11i standard before it was ratified.WPA uses
Temporal Key Integrity Protocol (TKIP) encryption. The Personal version uses WPA2.
Pre-Shared Key (PSK) allows the use of manually entered keys or passwords to initiate
WPA security.
Cisco Fast Secure Roaming
Cisco’s Fast Secure Roaming (FSR) mechanism uses a combination of standards-based
and proprietary security components including Cisco Client Key Management (CCKM),
LEAP authentication, Michael message integrity check (MIC) and Temporal Key Integrity
Protocol (TKIP). FSR provides strong security measures for authentication, privacy and
data integrity along with fast AP handoff on Cisco APs.
WEP
The handset supports Wired Equivalent Privacy (WEP) with both 40-bit and 128-bit
encryption.

12 Avaya 3641/3645/6120/6140 IP Wireless Handset SIP Administration Guide June 2012
Minimum system requirements
A wireless LAN must be properly configured and operational through the use of
802.11a/b/g/n wireless APs. Consult the Polycom VIEW Configuration Guide for the
appropriate make/model of WLAN. Configuration guides for the Polycom
SpectraLink®8020/8030 Wireless Telephones are considered by Avaya as useable
with the Avaya 3641/3645/6120/6140 IP Wireless Handsets.
To load software and configuration files to the handset over the air, an HTTP or
TFTP Server must be available on the network. You must install the current handset
software in the proper HTTP or TFTP download directory. If the handset cannot
connect to the server, the handset boots with the last known configuration.
If you use SVP for QoS, you must install and properly configure the SVP Server.
If you use SVP and/or the Avaya Wireless Application Interface Gateway, ensure
that you have the following software versions:
Component Version
Avaya SVP Server 17x.040 or higher
Avaya Wireless Application
Interface Gateway2
82.020 or higher
If you use Wi-Fi Standard QoS, you must configure each AP for such features as
WMM-Power Save; WMM-Admission Control; proper EDCA parameters; DSCP
mapping for voice and control traffic; call admission control and Proxy ARP. Consult
the appropriate VIEW Configuration Guide for these settings.
If you use WPA2-Enterprise, the handsets use the network only when you install and
properly configure all portions of the Public Key Infrastructure (PKI).
2The Avaya Wireless Application Interface Gateway is also referred to in this document as the “OAI Gateway”, “Open
Applications Interface Gateway” or simply “OAI”. The model number on the label is “MOG700.” The Installation
document for the Open Applications Interface (OAI) Gateway is available at
https://support.avaya.com/css/P8/documents/003745895.

System diagram
The following diagram shows the Avaya components residing on a network with APs and
wireless LAN Ethernet Switch.

14 Avaya 3641/3645/6120/6140 IP Wireless Handset SIP Administration Guide June 2012
System components
Avaya 3641/3645/6120/6140 IP Wireless Handset
The Avaya 3641/6120 IP Wireless Handset is a lightweight, durable handset specifically
designed for mobile workplace use. The Avaya 3645/6140 IP Wireless Handset has the
same features and function, but in a more durable design with and includes push-to-talk
and emergency call capability.
Like a wired deskphone, the handset can receive direct calls and transferred calls,
transfer calls to other extensions and make outside and long distance calls. The users
can use the wireless telephones only within the premises and within the WLAN coverage
area.
SVP Server (required when using SVP QoS)
SVP Server is a wired LAN device that is required when using SpectraLink Voice Priority
for QoS. This device may be referred to as the Avaya SVP Server, the Avaya Voice
Priority Processor or the Nortel WLAN IP Telephony Manager 2245. See the Avaya SVP
Server Admin Guide for complete information.
Access points
Enterprise-grade Wi-Fi access points provide the connection between the wired LAN
and the wireless LAN. To ensure seamless radio coverage, you must position the VIEW
certified 802.11a/b/g/n APs in all areas where IP Wireless Handsets will be used. The
number, type and placement of access points will affect the coverage area and capacity
of the wireless system. Careful planning of the WLAN is necessary to ensure good voice
quality. See the Best Practices Guide for Deploying SpectraLink 8020/8030 Wireless
Telephones for additional guidance.
You must properly configure the APs to support the corresponding QoS and security
methods selected for the handset.
Ethernet switch
One or more Ethernet switches interconnect multiple network devices, including the
Avaya SVP Server (if used for QoS), the proxy server(s), wired IP phones, HTTP/TFTP
Server, RADIUS authentication server (if using WPA2 Enterprise) and WLAN access
points. Enterprise Ethernet switches provide the highest performance networks, which
can handle combined voice and data traffic, and are required when using the Avaya
3641/3645/6120/6140 IP Wireless Handsets.
Although a single Ethernet switch network is recommended, the handsets and the Avaya
SVP Server can operate in larger, more complex networks, including networks with
multiple Ethernet switches, routers, VLANs and/or multiple subnets, as long as the SVP
Server and access points and handsets are on the same subnet. However, in such

Avaya 3641/3645 IP Wireless Handset Overview
Avaya 3641/3645/6120/6140 IP Wireless Handset SIP Administration Guide June 2012 15
networks, it is possible for the quality of service (QoS) features of the SVP Server to be
compromised, and consequently voice quality may suffer. Any network that consists of
more than a single Ethernet switch should be thoroughly tested to ensure any quality
issues are addressed. See Best Practices Guide for Deploying SpectraLink 8020/8030
Wireless Telephones for additional guidance.
Avaya 3641/3645/6120/6140 IP Wireless Handsets cannot roam with uninterrupted
service between subnets unless specific LAN components are present. Certain
AP/Ethernet switch combinations establish a Layer-2 tunnel across subnets that enable
the handsets to roam. Without this capability, the telephone drops any call in progress
when the user moves out of range. The handset must be power cycled in order to
resume functionality in the new subnet area.
Ensure that you have attached all your APs to the same subnet for proper operation.
The handset can change subnets if you have enabled DHCP and switch on the handset
within range of APs on a new subnet. Note that the wireless telephones cannot “roam”
across subnets, since their IP addresses do not change while operational.
Avaya Aura®Session Manager and Avaya Aura®Communications Manager
The Avaya Aura®Session Manager and Avaya Aura®Communications Manager
provides access to telephony services and connects to another device such as a PBX or
gateway and from there, other wired phones and the PSTN.
HTTP server
An HTTP server is required to distribute software to the handsets. In a system with no
HTTP server, you may use a TFTP server for this purpose.
TFTP (Trivial File Transfer Protocol) server
You may use a TFTP server to distribute software to the handsets if there is no HTTP
server. It may be on a different subnet than the APs and the handsets.
NTP (Network Time Protocol) Server
If you use WPA2 Enterprise security, the handset confirms if the PEAP certificate has a
valid date and time with the NTP server on the network, if the server is available. If an
NTP Server is not available, the certificate will be assumed valid and operate
accordingly. When you use an NTP server, the server provides date and time
information to the handset.
Authentication Server (if using WPA2 Enterprise)
You must use a RADIUS authentication server to provide username/password based
authentication using RSA certificates for PEAPv0/MSCHAPv2 or PAC files for EAP-
FAST.
You can use the following authentication servers with R3.0:
Juniper Networks Steel-belted Radius Enterprise Edition (formerly Funk), v6.1

16 Avaya 3641/3645/6120/6140 IP Wireless Handset SIP Administration Guide June 2012
Microsoft Internet Security and Acceleration (ISA) Server 2003
Cisco Secure Access Control Server (ACS), v4.1
FreeRADIUS v2.0.1 and 1.1.7
Other RADIUS servers may work properly with Avaya handsets, but have not been
tested. Inquiries on untested servers will receive limited, “Best Effort” support.
