Caution: Only qualified persons should service the system.
The installation and service of this hardware is to be performed only by service personnel
having appropriate training and experience necessary to be aware of hazards to which they
are exposed in performing a task and of measures to minimize the danger to themselves or
other persons.
Electrical shock hazards from the telecommunication network and AC mains are possible
with this equipment. To minimize risk to service personnel and users, the system must be
connected to an outlet with a third-wire ground. Service personnel must be alert to the
possibility of high leakage currents becoming available on metal system surfaces during
power line fault events near network lines. These leakage currents normally safely flow to
Protective Earth ground via the power cord. Therefore, it is mandatory that connection to
an earthed outlet is performed first and removed last when cabling to the unit. Specifically,
operations requiring the unit to be powered down must have the network connections
(central office lines) removed first.

computing device pursuant to Part 15 of the FCC Rules and with ICES.003, CLASS A
Canadian EMI Requirements. Operation of this equipment in a residential area is not
permitted and is likely to cause interference.
Repairs to certified equipment should be made by an authorized maintenance facility designated
by the supplier. Any repairs or alterations made by the user to this equipment, or equipment
malfunctions, may give the telecommunications company cause to request the user to disconnect
the equipment. Users should ensure for their own protection that the electrical ground connections
of the power utility, telephone lines and internal metallic water pipe system, if present, are
connected together. This precaution may be particularly important in rural areas.

Nortel Networks WLAN Handsets 2210/2211
Each of the WLAN Handsets 2210/2211 has a user guide that explains the specific feature access
for the handsets. Information about using the features of the WLAN Handsets 2210/2211 is
contained in the Nortel Networks WLAN Handset 2210/2211 User Guide.
In this document, the following handsets are referred to generically as “WLAN handsets”:
•
•
Nortel Networks WLAN Handset 2210
Nortel Networks WLAN Handset 2211
The WLAN Handsets 2210/2211 are very similar. The differences are the following:
•
The WLAN Handset 2211 is slightly larger and more rugged than the WLAN IP Handset
2210. It is more suitable in an environment where it might be knocked or bumped (for
example, in a warehouse). The WLAN Handset 2210 is sleeker, smaller, and lighter and is
more suitable for an office-type environment.
•
•
•
The WLAN Handset 2211 has a slightly larger battery pack, although the battery life is the
same for both models.
The WLAN Handset 2211 supports the Push-To-Talk (PTT) feature. PTT is not available on
the WLAN Handset 2210.
The WLAN Handset 2210 does not have an adjustable ringer volume.
IP telephones
This document references Nortel Networks IP Phone 2004. The IP Phone 2004 has a user card that
explains the buttons on the device, including the Featurebutton, which is a softkey located under
the display on the phone. The Telephone Feature User Guide can be used with this telephone, as
most Business Communications Manager (BCM) features can be accessed from this telephone.
The IP Phone 2004 also has a display menu that provides quick access to listed features.
The WLAN Handsets 2210/2211 have a separate feature card that provides a quick reference for
accessing the system through the handset. The card also explains how to access the BCM features

Overview
Description
The Nortel Networks Wireless Local Area Network Handsets 2210 and 2211 (WLAN Handsets
2210/2211) operate over an 802.11b wireless Ethernet LAN providing users a wireless Voice over
IP (VoIP). The WLAN Handsets 2210/2211 emulate the Nortel Networks IP Phone 2004 to
provide the VoIP functionality.
To be able to connect to the Business Communications Manager (BCM), the WLAN Handsets
2210/2211 must be supplied with the Internet Protocol (IP) address of the Nortel Networks WLAN
IP Telephony Manager 2245 and, optionally, a Trivial File Transfer Protocol (TFTP) Server. The
WLAN Handsets 2210/2211 accept IP address configuration parameters either from manual
configuration or from a Dynamic Host Configuration Protocol (DHCP) Server. DHCP automatic
discovery mode provides WLAN IP Telephony Manager 2245 and TFTP Server IP addresses to
the WLAN Handsets 2210/2211. In addition, DHCP allows the Unified Manager (UM) and BCM
Monitor to recognize the WLAN Handsets 2210/2211 as such. The BCM can be the DHCP Server,
or a separate DHCP Server can be installed in the network.
The 802.11b protocol provides no mechanism for differentiating audio packets from data packets.
The WLAN IP Telephony Manager 2245 provides a Quality of Service (QOS) mechanism that is
implemented in the WLAN Handsets 2210/2211 and the Access Points (APs) to enhance voice
quality over the wireless network. The WLAN IP Telephony Manager 2245 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 or no delay.
The WLAN Handsets 2210/2211 use the TFTP Server to update the wireless telephone firmware
over the 802.11b WLAN.
Note: In this document, Nortel Networks WLAN IP Telephony Manager 2245 refers to
the SpectraLink Voice Priority (SVP) Server.
Note: For the purposes of this book, it is assumed that site planning and deployment is
complete. A general description of the process is provided. This can assist you when
Network configuration
There are many possible configurations for a WLAN IP Telephony network. A typical
Overview

Figure 1 Basic network configuration
The basic WLAN IP Telephony network consists of the following components:
•
•
•
•
•
•
BCM (call server)
TFTP Server (optional)
DHCP Server (optional)
WLAN IP Telephony Manager 2245
WLAN Handset 2210/2211
Access Point (AP)
BCM
To support the WLAN Handsets 2210/2211, the BCM system must run Release 3.6.1 (patch) or
later software versions. BCM systems with 3.6 or earlier software versions must be upgraded to
support the handsets.
TFTP Server
A TFTP Server distributes firmware to the WLAN Handsets 2210/2211 and WLAN IP Telephony
Manager 2245. It can reside on a different subnet than the BCM and APs. The TFTP Server can be
located on either side of the firewall.
Overview
31
If too many wireless handsets are attempting to download new firmware simultaneously, the
downloads can slow down or error messages can be returned. To reduce the number of retries and
error messages, manage the download process by staggering the times the wireless handsets
download the firmware.
The TFTP Server must be capable of supporting multiple TFTP sessions.
Nortel Networks has tested the following TFTP Servers. They are listed in order of preference.

Assuming the IP address of the TFTP Server has been configured on the
WLAN Handsets 2210/2211, each time a WLAN handset is powered on, the following occurs:

3
The WLAN handset checks its version of firmware against the firmware on the TFTP Server,
which takes less than two seconds on a quiet network.
If the firmware versions are different, the WLAN handset downloads the new firmware from
the TFTP Server. This process takes about 30 seconds.
If the TFTP Server is offline or unreachable, the WLAN handset tries for about ten seconds
before giving up and using its existing version of firmware.
DHCP Server
For detailed DHCP Server instructions, refer to the Configuring DHCP chapter of the
Programming Operations Guide (N0008589).
DHCP is a standardized protocol that enables clients to be dynamically assigned with various
configuration parameters, such as:
•
•
•
•
IP address
subnet mask
default Gateway
other critical network configuration information
DHCP Servers centrally manage such configuration data, and are configured by network
administrators with settings that are appropriate for a given network environment.
Overview
32
The IP-related parameters of the WLAN Handsets 2210/2211 can be configured manually or
through a DHCP Server (RFC 1541 and RFC 1533). The DHCP Server can be on either side of the
firewall, according to the site administrator’s preference. The DHCP Server is optional if the
WLAN handsets and WLAN IP Telephony Manager 2245 are statically configured.
Each wireless handset effectively uses two IP addresses in the wireless subnet. One is for the
physical set, and one is the second alias IP address that is used on the WLAN IP Telephony
Manager 2245 Server. A contiguous block of addresses, equal to the number of handsets
supported, must be marked as unavailable for distribution when you allocate addresses in a subnet
scope on the DHCP Server.
The DHCP Server can require specific configuration modifications when multiple WLANs are
connected to a single Wireless Security Switch (WSS). Refer to the documentation that
accompanies the specific WSS being used for any special DHCP configuration requirements.
handset uses the DHCP options listed when DHCP use is enabled.

DHCP Option 66 - This can be used to specify the address of the TFTP Server. If this Option is
not present the phone will look at the Next server/ Boot server (siaddr) option for the address
of the TFTP server.
Vendor Specific Option 43, 128, 144, 157, 191, or 251 - Only one of these options is required.
The DHCP Server encodes the Server 1 information using the same format as the IP Phone
2004. If the Server 2 information is also present in the option, it is ignored.
DHCP Option 151 - This option contains the IP address of the WLAN IP Telephony Manager
2245. If Option 151 is not configured, the wireless handset performs a Domain Name Service
(DNS) lookup of the name “SLNKSVP2”, if Options 6 (DNS Server) and 15 (Domain Name)
are configured.
Overview

Firewall
In many installations there will be a firewall installed between the wired and wireless parts of the
network. It is beyond the scope of this document to specify how a firewall is managed, but the
following guidelines can be used when configuring firewalls:
•
The TFTP Server, DHCP Server, and Syslog Server can be anywhere in the network (that is,
they are not restricted to being in the same subnet as the handsets and WLAN IP Telephony
Manager 2245). From an administrative point of view, it may be more convenient to place
these components in the wired portion of the network. If a firewall is between the WLAN
Handsets 2210/2211, and the WLAN IP Telephony Manager 2245 and the servers, the firewall
will need to be configured to allow the TFTP (User Datagram Protocol [UDP] port 69 -
bidirectional) and Syslog traffic (UDP port 514 - unidirectional) and a DHCP relay agent.
•
When the WLAN Handsets 2210/2211 are hosted by a BCM, the following port numbers are
used:
— UNIStim signaling uses UDP port 7000
— Media to and from the handset uses UDP ports 51000–51200.
Note: The media ports are configurable. The values shown above are the default values.
•
•
•
If other Nortel call servers are used in the network (for example, BCM, MCS5100, CS2100),
the system administrator will need to determine which UDP ports are used for Realtime
Transport Protocol (RTP) and RTCP and make the appropriate provisions in the firewall.
If third party gateways are configured in the system, the system administrator will need to
determine which UDP ports are used for RTP and RTCP and make the appropriate provisions
in the firewall.
All media and signaling goes through the WLAN IP Telephony Managers 2245 (that is, it will
all originate from one, or a few, Media Access Control [MAC] addresses). If the firewall is
capable of filtering based on MAC address, the administrator can create a simple access
control filter based on a small number of MAC addresses.
Note: For IP Telephony firewall information, refer to the Optional VoIP trunk
configurations chapter in the 20XX IP Telephony Configuration Guide (N0008591). Also
refer to the Configuring IP Firewall Filters chapter of the Programming Operations
Guide (N0008589).
WLAN IP Telephony Manager 2245
The WLAN IP Telephony Manager 2245, also referred to as SVP II Server, is a device that
manages IP telephony network traffic on the WLAN IP Telephony system. It is required in order
to use the 11Mbit/s maximum transmission speed available in the WLAN Handsets 2210/2211.
The WLAN IP Telephony Manager 2245 acts as a proxy for the WLAN handsets. It provides a
number of services including a Quality of Service (QoS) mechanism, AP bandwidth management,
and efficient Radio Frequency (RF) link use.
Overview
34
The WLAN IP Telephony Manager 2245 works with the APs to provide QoS on the WLAN. All
voice packets are encapsulated by the WLAN handsets. The encapsulated voice packets to and
from the WLAN handsets are handled by the WLAN IP Telephony Manager 2245 and routed to
and from the BCM.
SVP is the QoS mechanism implemented on the WLAN handsets and APs 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 with minimum
delay. SVP is fully compliant with the IEEE 802.11 and 802.11b standards.
Each subnet where the WLAN handsets operate requires at least one WLAN IP Telephony
Manager 2245. One unit can process 90 simultaneous calls. If greater capacity is required, multiple
units can be used in a master-slave arrangement.
Note: The WLAN Handset 2211 uses IP multicast addresses for the Push-To-Talk (PTT)
feature. This requires that multicasting be enabled on the subnet used for the WLAN
Handset 2211 and the WLAN IP Telephony Manager 2245. Refer to the Nortel Networks
WLAN Handset 2210/2211 User Guide for more information on the PTT feature.

Functional description
The WLAN IP Telephony Manager 2245 provides the following services to the WLAN Handsets
2210/2211:
•
It acts as a proxy for every WLAN handset; that is, all Unified Networks IP Stimulus
(UNIStim) signaling and RTP media to and from the wireless handset pass through the WLAN
IP Telephony Manager 2245. Except for the initial DHCP and TFTP sessions, the wireless
handsets only communicate with the WLAN IP Telephony Manager 2245.
Each WLAN IP Telephony Manager 2245 is configured with an IP address with which all of
the wireless handsets communicate. In addition, each WLAN IP Telephony Manager 2245 is
configured with a pool of IP addresses. When a wireless handset registers with a WLAN IP
Telephony Manager 2245, the wireless handset is assigned one of the IP addresses from the
pool. All communication between this WLAN IP Telephony Manager 2245 and other devices
(BCM, IP Phones, gateways, and other wireless handsets) is always done through its pool of IP
addresses. In this sense, the WLAN IP Telephony Manager 2245 acts as a Network Address
Translation (NAT).
The WLAN IP Telephony Manager 2245 has a single physical Ethernet interface and MAC
address. Therefore, all of the IP addresses are mapped to a single MAC address.
•
The WLAN IP Telephony Manager 2245 tags and untags packets with the SVP header. SVP
packets have the protocol byte of the IP header set to 0x77. SVP-compliant APs use this
proprietary tagging to give priority to tagged packets. For UDP (UNIStim and RTP) packets
going from the wireless handset to the network, the WLAN IP Telephony Manager 2245
replaces the SVP protocol number, 0x77, with the UDP number, 0x11. For packets going from
the network to the wireless handset, the protocol number is changed from 0x11 to 0x77.
There can be no Layer 3 routing in the path because packets that traverse the network between
the wireless handset and the WLAN IP Telephony Manager 2245 are not standard IP packets
(the packets use a non-standard protocol number). Therefore, the wireless handsets and
WLAN IP Telephony Managers 2245 must be in the same logical subnet.
Overview
36
•
RTP packets between the wireless telephone and the WLAN IP Telephony Manager 2245
always contain 30 milliseconds (ms) worth of voice, regardless of what has been configured
on the BCM. The WLAN IP Telephony Manager 2245 repackages the RTP packets to conform
to the size that has been configured in the BCM. This provides more efficient use of the
available RF bandwidth at the expense of slightly increased jitter and latency.
•
•
The WLAN IP Telephony Manager 2245 is configured with a maximum allowable number of
simultaneous media streams on a single AP. The WLAN IP Telephony Manager 2245 keeps
track of the number of media streams on each AP and blocks calls to and from a wireless
handset that would exceed the configured capacity.
There is a keep-alive packet exchange that runs between the wireless handset and the WLAN
IP Telephony Manager 2245 every 30 seconds. If the wireless handset detects the WLAN IP
Telephony Manager 2245 is unreachable, the wireless handset resets itself and attempts to
re-establish a connection with the master WLAN IP Telephony Manager 2245, where there is
more than one WLAN IP Telephony 2245 in the system.
Capacities
The WLAN IP Telephony Manager 2245 requires a CAT5 cable connection between its network
port and the Ethernet switch. The WLAN IP Telephony Manager 2245 auto-negotiates to the type
of port on the Ethernet switch and supports 10BaseT, 100BaseT, full-duplex, and half-duplex port
types.
In any subnet where wireless handsets are used, each subnet must have one or more WLAN IP
Telephony Managers 2245. A WLAN IP Telephony Manager 2245 group on a subnet consists of
one or more WLAN IP Telephony Managers 2245 and their associated wireless handsets. Only
one master WLAN IP Telephony Manager 2245 can be on a subnet.
The WLAN infrastructure, if properly deployed, can support the same capacity offered in the
BCM for IP terminals. When planning for WLAN set deployment, follow standard BCM IP
terminal engineering practices. When planning your WLAN infrastructure deployment, follow
your AP vendor’s standard voice deployment site survey practices.
WLAN IP Telephony Manager 2245 firmware upgrade
When a WLAN IP Telephony Manager 2245 reboots or is manually reset by the operator, the
following occurs:
1
2
The WLAN IP Telephony Manager 2245 checks its version of firmware against the version on
the TFTP Server.
If the firmware versions are different, the WLAN IP Telephony Manager 2245 downloads the
new firmware.

Roaming and handover
Roaming is the ability of the wireless handset to go anywhere in the WLAN Extended Service Set
(ESS) RF signal coverage area and to make and receive calls. Handover is the ability of the
wireless handset to maintain an active call without interruption while moving within a WLAN ESS
RF signal coverage area. This means that the wireless handset hands over the WLAN RF signal
from AP to AP without interrupting the data stream.
APs on the same subnet
The WLAN Handsets 2210/2211 can perform handover and roaming across SVP-compliant APs
that reside on the same subnet as the wireless handset and WLAN IP Telephony Manager 2245
APs on different subnets using WSS
If you use Nortel Networks WSS 2250/2270 and Nortel Networks Access Ports 2230, both
operating in Layer 3 mode, the WLAN Handsets 2210/2211 can perform roaming and handover
across Access Ports 2230 on different subnets. The WSS 2270 operating in Layer 3 mode is on the
same subnet as the WLAN IP Telephony Manager 2245 group. The WSS 2270 allows the wireless
handset to retain its original IP address, whether the IP address was configured statically or
obtained by DHCP. This means that roaming and handover can occur across Access Ports 2230
placed on any subnet.
Note: The WSS 2270 must be running version 2.0.71.0 (or later) software.
Overview
38
Mobility across different subnets when using DHCP
If a WSS is not in use, and the IP address of the wireless handset has been acquired through
DHCP, the wireless handset must be powered down and powered up when entering a new subnet.
This enables functionality of the wireless handset when entering the WLAN RF signal coverage
area of a different WLAN IP Telephony Manager 2245 group on a different subnet. Normal
functionality returns once the wireless handset:
•
•
•
establishes communication within the Extended Service Set ID (ESSID) of the new WLAN
obtains another IP address from the DHCP Server
checks in with the group master
If the wireless handset is configured to use the ESSID of the new WLAN, it automatically
discovers the ESSID of the APs operating in broadcast mode.

Access Point
The 802.11b APs provide the connection between the wired Ethernet LAN and the wireless
(802.11) LAN. APs work in all markets and must be positioned in all areas where the WLAN
handsets are used. The number and placement of APs affects the coverage area and capacity of the
WLAN IP Telephony system. Typically, the requirements for use of WLAN Handsets 2210/2211
are similar to those of other wireless data devices.
The APs must be SVP-compliant to support QoS. For a list of supported APs, refer to Appendix A:
When a user on an active call is moving about, the call switches from one AP to another in the
subnet. This changeover is transparent to the user.
Overview
39
It is essential to know where to install the APs to provide effective coverage for the WLAN
handsets. The first step is to define exactly where the coverage is needed, which requires a site
Tips: A site survey must be performed before installing a wireless LAN. Nortel Networks
also recommends a site survey when an existing network structure is modified or when
physical changes are made to a site.
Nortel Networks recommends the use of the Nortel Networks Site Survey Tool to perform
the site survey.
Network planning
.It is necessary to ensure that all connections and interfaces for the IP Telephony network be
configured as full-duplex. Duplex mismatches anywhere on the WLAN can cause the wireless IP
Telephony system not to function normally.
IP address planning
The WLAN IP Telephony Manager 2245, the optional WLAN Application Gateway 2246, and
each of the wireless handsets and APs associated with them, requires an IP address.
Note: The master WLAN IP Telephony Manager 2245 must have an IP address statically
configured. If using DHCP for the rest of the network, the DHCP Server must have the
static IP address of the master WLAN IP Telephony Manager 2245 configured on it. If
using DNS, the DNS Server must have the static IP address of the master WLAN IP
Telephony Manager 2245 configured on it.
The wireless handsets can be configured to use DHCP or can be assigned a static IP address. If
there is no DHCP Server, the system administrator must determine what IP addresses are to be
used for static addressing. As well, whether static IP addressing or DHCP is used, a pool of alias IP
addresses must be configured on the WLAN IP Telephony Manager for the use of the wireless
handsets. Ensure that the pool of alias IP addresses is reserved exclusively for the use of the
wireless handsets.
configuring a static IP address on a WLAN IP Telephony Manager 2245. Refer to “Configuring
the network” on page 48 for information on configuring a static IP address for a WLAN
static IP address on the WLAN Handsets 2210/2211. Refer to the vendor-specific documentation
for information on assigning IP addresses to the APs.
Tip: Record the static IP address assignments and store them in a safe place.
Overview
40
IP addressing with DHCP
A pool of alias IP addresses must be configured on the WLAN IP Telephony Manager 2245 for the
addresses on the WLAN IP Telephony Manager 2245.
The use of a 22-bit subnet mask provides IP addresses for approximately 500 wireless handsets
(1024 nodes). Allocate a pool of an equal number of IP addresses on the DHCP Server and WLAN
IP Telephony Manager 2245 for the wireless handsets.
For example:
142.223.204.1 to 142.223.205.254 are allocated on the DHCP Server for the use of the wireless
handsets.
142.223.206.1 to 142.223.207.254 are configured on the WLAN IP Telephony Manager for IP
aliases for the wireless handsets.
Ensure that all these IP addresses are reserved on the DHCP Server for the use of the wireless
handsets and not assigned to any other device.
Programming Records
Use the WLAN Programming Records spreadsheet (a Microsoft ExcelTM file) to record settings for
each handset. The spreadsheet is located on the BCM documentation CD. Use the recorded
page 55 for instructions on configuring the handsets.

WLAN Handsets 2210/2211 configuration
This section describes the WLAN Handsets 2210/2211 and explains how to configure them.
Tasks:
• Configure WLAN Handset 2210 and WLAN Handset 2211 (“Configuring the WLAN Handsets
• Program the features on the WLAN handsets (“Programming the WLAN Handsets 2210/2211”
• Test the WLAN handsets (“Appendix C: Testing the WLAN Handsets 2210/2211” on page
109)
Note: The WLAN Handsets 2210/2211 require special configuration to enable them to
communicate with the optional WLAN Application Gateway 2246. Ensure that these
WLAN Handsets 2210/2211
The WLAN Handsets 2210/2211 use VoIP technology on IEEE 802.11-compliant WLANs. APs
use radio frequencies to transmit signals to and from the WLAN handsets.
Employees carry WLAN handsets to make and receive calls as they move throughout the building.
The WLAN handsets are used only on the premises; they are not cellular phones. Just like wired
telephones, the WLAN handsets receive calls directly, receive transferred calls, transfer calls to
other extensions, and make outside and long-distance calls (subject to corporate restrictions).
The radio frequencies use Spread Spectrum radio technology, which comes in two variations:
•
•
Direct Sequence (DS)
Frequency Hopping (FH)
The WLAN Handsets 2210/2211 use Direct Sequence Spread Spectrum (DSSS) radio technology
to optimize bandwidth and minimize jitter on the WLAN IP Telephony network. The WLAN
handsets are not compatible with FH.
The WLAN Handsets 2210/2211 on an 802.11b network operate at a transmission rate of up to
11 Mbit/s in a DSSS system.

Language
The menus and screens of the WLAN Handsets 2210/2211 display in English only. International
characters are supported for BCM prompts, depending on the market profile. BCM-based prompts
display in English, French, and Spanish.
Wired Equivalent Privacy
The WLAN Handsets 2210/2211 support Wired Equivalent Privacy (WEP) as defined by the
802.11b specification. WEP increases the security of the wireless LAN to a level similar to a wired
Ethernet LAN. WEP is turned on and off using the APs.
Loss of signal
If a wireless handset is out of range of all APs, it waits 20 seconds for a signal to return. If a signal
is not re-acquired within 20 seconds, the wireless handset loses connection to the BCM and any
calls are dropped. When the wireless handset comes back into range of an AP, it re-establishes a
connection to the BCM and goes through the system registration process.
Note: If a wireless handset is out of contact with the system for four seconds during the
UNIStim messaging process (worst case scenario), then a UNIStim failure could result.
This can cause the wireless handset to lose the UNIStim association with the BCM.

Codecs
The WLAN Handsets 2210/2211 are compatible with the G.711 and G.729a/ab codecs. No
configuration is required on the wireless handsets.
If the WLAN Handsets 2210/2211 are registered to the same BCM as IP Phone 200x sets, then the
system administrator must configure only the subset of codecs that is supported by both the
WLAN Handsets 2210/2211 and the IP Phone 200x sets.
If it is necessary for the IP Phone 200x to use a codec that is not supported on the WLAN Handsets
2210/2211 (for example, G.723.1), the wireless handsets must be configured on their own separate
node.
Jitter buffer
The WLAN Handsets 2210/2211 do not support a configurable jitter buffer. If they receive the
Jitter Buffer ConfigurationUNIStim message, the command is ignored. Any
adjustment to the jitter buffer setting has no effect on the handsets.
RTP and RTCP
The WLAN Handsets 2210/2211 do not support RTCP. If RTCP packets are sent to the phone
(these are actually sent to the WLAN IP Telephony Manager 2245), they are discarded. When the
handsets are queried for their RTCP statistics, the handsets respond with 0 for jitter, 0 for latency
and 0 for packet loss.
IP Phone 2004 mapping
The WLAN Handsets 2210/2211 emulate the IP Phone 2004. All IP Phone 2004 functions and
messaging features are supported, where possible. The speakerphone function and functions that
information on the limitations of the WLAN Handsets 2210/2211.
The large screen area of the IP Phone 2004 and its numerous keys are mapped onto the smaller
screen and fewer buttons of the wireless handsets. The button mapping from the IP Phone 2004 to
the WLAN Handsets 2210/2211 is designed to preserve nearly all of the functionality of the IP
Phone 2004 within a small, mobile device.
