Cisco IP Phone 8800 Series Wireless LAN Deployment Guide

Cisco IP Phone 8800 Series Overview
The Cisco IP Phone 8800 Series is the platform that provides collaboration within enterprises. It brings together the capabilities
of Cisco Unified Communication applications, building upon the solid foundations of Cisco Unified Communications devices,
both wired and wireless.
Cisco’s implementation of 802.11, employing CCX, permits time sensitive applications such as voice and video to operate
efficiently across campus wide wireless LAN (WLAN) deployments. These extensions provide fast roaming capabilities and an
almost seamless flow of multimedia traffic, whilst maintaining security as the end user roams between access points.
It should be understood that WLAN uses unlicensed spectrum, and as a result it may experience interference from other devices
using the unlicensed spectrum. The proliferation of devices in the 2.4 GHz spectrum, such as Bluetooth headsets, Microwave
ovens, cordless consumer phones, means that the 2.4 GHz spectrum may contain more congestion than other spectrums. The 5
GHz spectrum has far fewer devices operating in this spectrum and is the preferred spectrum to operate the Cisco IP Phone
8800 Series in order to take advantage of the 802.11a/n/ac data rates available. Despite the optimizations that Cisco have
implemented in the Cisco IP Phone 8800 Series, the use of unlicensed spectrum means that uninterrupted communication can
not be guaranteed, and there may be the possibility of voice gaps of up to several seconds during multimedia conversations.
Adherence to the deployment guidelines will reduce the likelihood of these voice gaps being present, but there is always this
possibility. Through the use of unlicensed spectrum, and the inability to guarantee the delivery of messages to a WLAN device,
the Cisco IP Phone 8800 Series is not intended as a medical device and should not be used to make clinical decisions.
Requirements
The Cisco IP Phone 8800 Series is an IEEE 802.11a/b/g/n/ac device that provides voice communications.
The wireless LAN must be validated to ensure it meets the requirements to deploy the Cisco IP Phone 8800 Series.
Site Survey
Before deploying the Cisco IP Phone 8800 Series into a production environment, a site survey must be completed by a Cisco
certified partner with the advanced wireless LAN specialization. During the site survey the RF spectrum can be analyzed to
determine which channels are usable in the desired band (5 GHz or 2.4 GHz). Typically there is less interference in the 5 GHz
band as well as more non-overlapping channels, so 5 GHz is the preferred band for operation and even more highly
recommended when the Cisco IP Phone 8800 Series is to be used in a mission critical environment. The site survey will include
heatmaps showing the intended coverage plan for the location. The site survey will also determine which access point platform
type, antenna type, access point configuration (channel and transmit power) to use at the location. It is recommended to select
an access point with integrated antennas for non-rugged environments (e.g. office, healthcare, education, hospitality) and an
access point platform requiring external antennas for rugged environments (e.g. manufacturing, warehouse, retail).
See the Designing the Wireless LAN for Voice section for more information.
Refer to the Steps to Success website for additional information.
http://www.cisco.com/go/stepstosuccess
RF Validation
In order to determine if VoWLAN can be deployed, the environment must be evaluated to ensure the following items meet
Cisco guidelines.
Signal
The cell edge should be designed to -67 dBm where there is a 20-30% overlap of adjacent access points at that signal
level.
This ensures that the Cisco IP Phone 8800 Series always has adequate signal and can hold a signal long enough in order
to roam seamlessly where signal based triggers are utilized vs. packet loss triggers.

Cisco IP Phone 8800 Series Wireless LAN Deployment Guide

Also need to ensure that the upstream signal from the Cisco IP Phone 8800 Series meets the access point’s receiver
sensitivity for the transmitted data rate. Rule of thumb is to ensure that the received signal at the access point is -67
dBm or higher.
It is recommended to design the cell size to ensure that the Cisco IP Phone 8800 Series can hold a signal for at least 5
seconds.
Channel Utilization
Channel Utilization levels should be kept under 40%.
The Cisco IP Phone 8800 Series converts the 0-255 scale value to a percentage, so 105 would equate to around 40% in
the Cisco IP Phone 8800 Series current access point menu.
Noise
Noise levels should not exceed -92 dBm, which allows for a Signal to Noise Ratio (SNR) of 25 dB where a -67 dBm
signal should be maintained.
Also need to ensure that the upstream signal from the Cisco IP Phone 8800 Series meets the access point’s signal to
noise ratio for the transmitted data rate.
Packet Loss / Delay
Per voice guidelines, packet loss should not exceed 1% packet loss; otherwise voice quality can be degraded
significantly.
Jitter should be kept at a minimal (< 100 ms).
Retries
802.11 retransmissions should be less than 20%.
Multipath
Multipath should be kept to a minimal as this can create nulls and reduce signal levels.
Many different tools and applications can be used to evaluate these items in order to certify the deployment.

A power cube (CP-PWR-CUBE-4=) is required when utilizing the Cisco IP Phone 8861 in Wi-Fi mode.
Note: Channels 120, 124, 128 are not supported in the Americas, Europe, or Japan, but may be in other regions around the
world.
802.11j (channels 34, 38, 42, 46) are not supported.
Channel 14 for Japan is not supported.
World Mode (802.11d)
World Mode allows a client to be used in different regions, where the client can adapt to using the channels and transmit powers
advertised by the access point in the local environment.
The Cisco IP Phone 8800 Series requires the access point to be 802.11d enabled, where it can then determine which channels
and transmit powers to use.
Enable World Mode (802.11d) for the corresponding country where the access point is located.
Some 5 GHz channels are also used by radar technology, which requires that the 802.11 client and access point be 802.11h
compliant if utilizing those radar frequencies (DFS channels). 802.11h requires 802.11d to be enabled.
The Cisco IP Phone 8800 Series will passively scan DFS channels first before engaging in active scans of those channels.
If using 2.4 GHz (802.11b/g/n) and 802.11d is not enabled, then the Cisco IP Phone 8800 Series can attempt to use channels 1-
11 and reduced transmit power.
Note: World Mode is enabled automatically for the Cisco Unified Wireless LAN Controller.
World Mode must be enabled manually for Cisco Autonomous Access Points using the following commands:
Interface dot11radio X
world-mode dot11d country US both

Cisco IP Phone 8800 Series Wireless LAN Deployment Guide
15
To achieve 802.11n/ac connectivity, it is recommended that the Cisco IP Phone 8800 Series be within 100 feet of the access
point.
See the Designing the Wireless LAN for Voice section for more information on signal requirements.
Language Support
The Cisco IP Phone 8800 Series currently supports the following languages.
The corresponding locale package must be installed to enable support for that language. English is the default language on the
phone.
Download the locale packages from the Localization page at the following URL:
http://software.cisco.com/download/navigator.html?mdfid=278875240
Bluetooth
The Cisco IP Phone 8800 Series supports Bluetooth 3.0 technology allowing for wireless headset communications.
Bluetooth enables low bandwidth wireless connections within a range of 30 feet, however it is recommended to keep the
Bluetooth device within 10 feet of the Cisco IP Phone 8800 Series.
Up to ten headsets can be paired, where the previously connected headset is given priority.
The Bluetooth device does not need to be within direct line-of-sight of the phone, but barriers, such as walls, doors, etc. can
potentially impact the quality.
Bluetooth utilizes the 2.4 GHz frequency just like 802.11b/g/n and many other devices (e.g. microwave ovens, cordless phones,
etc.), so the Bluetooth quality can potentially be interfered with due to using this unlicensed frequency.
Bluetooth Profiles
The Cisco IP Phone 8800 Series supports the following Bluetooth profiles.
Arabic
French
Polish

Hands-Free Profile (HFP)
With Bluetooth Hands-Free Profile (HFP) support, the following features can be available if supported by the Bluetooth
headset.
•Ring
•Answer a call
•End a call
•Volume Control
•Last Number Redial
•Call Waiting
•Divert / Reject
•3 way calling (Hold & Accept and Release & Accept)
•Speed Dialing
Phone Book Access Profile (PBAP)
Phone Book Access Profile (PBAP) support enables the exchange of phone book objects between devices.
For more information, refer to the documentation from the Bluetooth headset manufacturer.
Coexistence (802.11b/g/n + Bluetooth)
If using Coexistence where 802.11b/g/n and Bluetooth are used simultaneously, then there are some limitations and deployment
requirements to be considered as they both utilize the 2.4 GHz frequency range.
Capacity
When using Coexistence (802.11b/g/n + Bluetooth), call capacity is reduced due to the utilization of CTS to protect the
802.11g/n and Bluetooth transmissions.
Multicast Audio
Multicast audio from Push To Talk (PTT), Music on Hold (MMOH) and other applications are not supported when using
Coexistence.
Voice Quality
Depending on the current data rate configuration, CTS may be sent to protect the Bluetooth transmissions when using
Coexistence.
In some environments, 6 Mbps may need to be enabled.
Note: It is highly recommended to use 802.11a/n/ac if using Bluetooth due to 802.11b/g/n and Bluetooth both utilizing 2.4
GHz, but also due to the above limitations.
Security
When deploying a wireless LAN, security is essential.
The Cisco IP Phone 8800 Series supports the following wireless security features.

Cisco IP Phone 8800 Series Wireless LAN Deployment Guide
17
WLAN Authentication
•WPA2 (802.1x authentication + AES or TKIP encryption)
•WPA (802.1x authentication + TKIP or AES encryption)
•WPA2-PSK (Pre-Shared key + AES encryption)
•WPA-PSK (Pre-Shared key + TKIP encryption)
•EAP-FAST (Extensible Authentication Protocol - Flexible Authentication via Secure Tunneling)
•PEAP-MSCHAPv2 (Protected Extensible Authentication Protocol - Microsoft Challenge Handshake Authentication
Protocol version 2)
•802.11r / Fast Transition (FT)
•CCKM (Cisco Centralized Key Management)
•None
WLAN Encryption
•AES (Advanced Encryption Standard)
•TKIP / MIC (Temporal Key Integrity Protocol / Message Integrity Check)
•WEP (Wired Equivalent Protocol) 40/64 and 104/128 bit
Note: Dynamic WEP with 802.1x authentication and Shared Key authentication are not supported.
EAP-TLS authentication via X.509 digital certificates is currently not supported.
PEAP + Server Validation is currently not supported.
The Cisco IP Phone 8800 Series also supports the following additional security features.
•Image authentication
•Device authentication
•File authentication
•Signaling authentication
•Secure Cisco Unified SRST
•Media encryption (SRTP)
•Signaling encryption (TLS)
•Certificate authority proxy function (CAPF)
•Secure profiles
•Encrypted configuration files
•Settings Access (can limit user access to configuration menus)
Extensible Authentication Protocol - Flexible Authentication via Secure
Tunneling (EAP-FAST)
Extensible Authentication Protocol - Flexible Authentication via Secure Tunneling (EAP-FAST) encrypts EAP transactions
within a Transport Level Security (TLS) tunnel between the access point and the Remote Authentication Dial-in User Service
(RADIUS) server such as the Cisco Access Control Server (ACS) or Cisco Identity Services Engine (ISE).

Cisco IP Phone 8800 Series Wireless LAN Deployment Guide
18
The TLS tunnel uses Protected Access Credentials (PACs) for authentication between the client (the Cisco IP Phone 8800
Series) and the RADIUS server. The server sends an Authority ID (AID) to the client, which in turn selects the appropriate
PAC. The client returns a PAC-Opaque to the RADIUS server. The server decrypts the PAC with its master-key. Both
endpoints now have the PAC key and a TLS tunnel is created. EAP-FAST supports automatic PAC provisioning, but it must
enable don the RADIUS server.
To enable EAP-FAST, a certificate must be installed on to the RADIUS server.
The Cisco IP Phone 8800 Series currently supports only automatic provisioning of the PAC, so enable Allow anonymous in-
band PAC provisioning on the RADIUS server as shown below.
Both EAP-GTC and EAP-MSCHAPv2 must be enabled when Allow anonymous in-band PAC provisioning is enabled.
EAP-FAST requires that a user account be created on the authentication server.
If anonymous PAC provisioning is not allowed in the production wireless LAN environment then a staging RADIUS server can
be setup for initial PAC provisioning of the Cisco IP Phone 8800 Series.
This requires that the staging RADIUS server be setup as a slave EAP-FAST server and components are replicated from the
product master EAP-FAST server, which include user and group database and EAP-FAST master key and policy info.
Ensure the production master EAP-FAST RADIUS server is setup to send the EAP-FAST master keys and policies to the
staging slave EAP-FAST RADIUS server, which will then allow the Cisco IP Phone 8800 Series to use the provisioned PAC in
the production environment where Allow anonymous in-band PAC provisioning is disabled.
When it is time to renew the PAC, then authenticated in-band PAC provisioning will be used, so ensure that Allow
authenticated in-band PAC provisioning is enabled.
Ensure that the Cisco IP Phone 8800 Series has connected to the network during the grace period to ensure it can use its existing
PAC created either using the active or retired master key in order to get issued a new PAC.
Is recommended to only have the staging wireless LAN pointed to the staging RADIUS server and to disable the staging access
point radios when not being used.

Cisco IP Phone 8800 Series Wireless LAN Deployment Guide

Protected Extensible Authentication Protocol (PEAP)
Protected Extensible Authentication Protocol (PEAP) uses server-side public key certificates to authenticate clients by creating
an encrypted SSL/TLS tunnel between the client and the authentication server.
The ensuing exchange of authentication information is then encrypted and user credentials are safe from eavesdropping.
PEAP-MSCHAPv2 is the supported inner authentication protocols. PEAP-GTC is not supported currently.
PEAP requires that a user account be created on the authentication server.

following links.

Fast Secure Roaming (FSR)
802.11r / Fast Transition (FT) is the recommended deployment model for all environment types where frequent roaming occurs.
Cisco Centralized Key Management (CCKM) is also supported, but requires 802.1x authentication.
802.11r (FT) and CCKM enable fast secure roaming and limits the off-network time to keep audio gaps at a minimum when on
call.
802.1x or PSK without 802.11r (FT) and 802.1x without CCKM can introduce delay during roaming due to its requirement for
full re-authentication. WPA and WPA2 introduce additional transient keys and can lengthen roaming time.
802.11r (FT) and CCKM centralizes the key management and reduces the number of key exchanges.
When 802.11r (FT) or CCKM is utilized, roaming times can be reduced from 400-500 ms to less than 100 ms, where that
transition time from one access point to another will not be audible to the user.
There are two types of 802.11r (FT) roaming.
•Over the Air
The client communicates directly with the target access point using 802.11 authentication with the FT authentication
algorithm.
•Over the Distribution
The client communicates with the target access point through the current access point. The communication between
the client and the target access point is carried in FT action frames between the client and the current access point via
the WLAN controller.

Power Management
The power supply (CP-PWR-CUBE-4=) is required to enable the Cisco IP Phone 8861 for wireless LAN mode, as there is no
internal battery.
Wireless LAN is automatically disabled temporarily when Ethernet is connected to the Cisco IP Phone 8861, but will be
automatically re-enabled once Ethernet is disconnected if Wireless LAN was enabled previously.
The Cisco IP Phone 8861 primarily uses active mode (no Wi-Fi power save) when in idle or on call.
Null Power Save (PS-NULL) frames are utilized for off-channel scanning.
