Cisco IP Phone 8861 and 8865 Overview
The Cisco IP Phone 8861 and 8865 are the platforms that provide 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 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
8861 and 8865 in order to take advantage of the 802.11a/n/ac data rates available.
Despite the optimizations that Cisco has implemented in the Cisco IP Phone 8861 and 8865, 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 conversations. Adherence to these 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 8861 and 8865 is not intended to be used as a medical device and should not be used to make clinical decisions.

Requirements
The Cisco IP Phone 8861 and 8865 are IEEE 802.11a/b/g/n/ac devices that provide voice communications.
The environment must be validated to ensure it meets the requirements to deploy the Cisco IP Phone 8861 and 8865.
Site Survey
Before deploying the Cisco IP Phone 8861 and 8865 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 8861 and 8865 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).
The wireless LAN must be validated to ensure it meets the requirements to deploy the Cisco IP Phone 8861 and 8865.
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 8861 and 8865 always have adequate signal and can hold a signal long enough in
order to roam seamlessly where signal based triggers are utilized vs. packet loss triggers.
Also need to ensure that the upstream signal from the Cisco IP Phone 8861 and 8865 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 8861 and 8865 can hold a signal for at least
5 seconds.
Channel Utilization
Channel Utilization levels should be kept under 40%.
The Cisco IP Phone 8861 and 8865 convert the 0-255 scale value to a percentage, so 105 would equate to around 40%
in the Cisco IP Phone 8861 and 8865.
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 8861 and 8865 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%.

Cisco IP Phone 8861 and 8865 Wireless LAN Deployment Guide
8
Multipath
Multipath should be kept to a minimal as this can create nulls and reduce signal levels.
Call Control
The Cisco IP Phone 8861 and 8865 utilize Session Initiation Protocol (SIP) for call control with the following applications.
• Cisco Unified Communications Manager (CUCM)
Minimum = 8.5(1)
Recommended = 8.6(2), 9.1(2), 10.5(2), 11.0(1), 11.5(1), and later
• Cisco Unified Communications Manager Express (CUCME)
Minimum = 10.0
Recommended = 11.0, 11.5, 11.7, and later
• Cisco Unified Survivable Remote Site Telephony (SRST)
Minimum = 10.0
Recommended = 11.0, 11.5, 11.7, and later
Note: Cisco Unified Communications Manager requires a device package to be installed or service release update in order to
enable Cisco IP Phone 8861 and 8865 device support.
Device packages for Cisco Unified Communications Manager are available at the following location.
http://software.cisco.com/download/navigator.html?mdfid=278875240
Prior to release 11.0 of Cisco Unified Communications Manager Express, the Cisco IP Phone 8861 and 8865 are to utilize the
fast track method utilizing the Cisco Unified IP Phone 9971 as the reference model (use 7975 as reference model if needing
softkey template support).
With release 11.0 and 11.5 of Cisco Unified Communications Manager Express, the Cisco IP Phone 8865 can utilize the Cisco
IP Phone 8861 as the reference model.
With release 11.7 and later of Cisco Unified Communications Manager Express, there is native support for the Cisco IP Phone
8865, therefore can use the Cisco IP Phone 8865 as the model type.

Note: Receiver sensitivity is the minimum signal needed to decode a packet at a certain data rate.
The above values are pure radio specifications and do not account for the gain of the single integrated antenna.
To achieve 802.11n/ac connectivity, it is recommended that the Cisco IP Phone 8861 and 8865 be within 100 feet of the access
point.
Regulatory
World Mode (802.11d) 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 8861 and 8865 operate best when the access point is 802.11d enabled, where it can determine which
channels and transmit powers to use per the local region.
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 8861 and 8865 will passively scan DFS channels first before engaging in active scans of those channels.
If 802.11d is not enabled, then the Cisco IP Phone 8861 and 8865 can attempt to connect to the access point using reduced
transmit power.

Bluetooth
The Cisco IP Phone 8861 and 8865 support 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 8861 and 8865.
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 8861 and 8865 support the following Bluetooth profiles.
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)

Cisco IP Phone 8861 and 8865 Wireless LAN Deployment Guide
17
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 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.
Languages
The Cisco IP Phone 8861 and 8865 currently support the following languages.
The corresponding locale package must be installed to enable support for that language. English is the default language on the
phone.

Wireless LAN Design
The following network design guidelines must be followed in order to accommodate for adequate coverage, call capacity and
seamless roaming for the Cisco IP Phone 8861 and 8865.
802.11 Network
Use the following guidelines to assist with deploying and configuring the wireless LAN.
5 GHz (802.11a/n/ac)
5 GHz is the recommended frequency band to utilize for operation of the Cisco IP Phone 8861 and 8865.
In general, it is recommended for access points to utilize automatic channel selection instead of manually assigning channels to
access points.
If there is an intermittent interferer, then the access point or access points serving that area may need to have a channel statically
assigned.
The Cisco IP Phone 8861 and 8865 support Dynamic Frequency Selection (DFS) and Transmit Power Control (TPC) from
802.11h, which are required when using channels operating at 5.260 - 5.720 GHz, which are 15 of the 24 possible channels.
Need to ensure there is at least 20 percent overlap with adjacent channels when deploying the Cisco IP Phone 8861 and 8865 in
an 802.11a/n/ac environment, which allows for seamless roaming. For critical areas, it is recommended to increase the overlap
(30% or more) to ensure that there can be at least 2 access points available with -67 dBm or better, while the Cisco IP Phone
8861 and 8865 also meet the access point’s receiver sensitivity (required signal level for the current data rate).
Dynamic Frequency Selection (DFS)
DFS dynamically instructs a transmitter to switch to another channel whenever radar signal is detected. If the access point
detects radar, the radio on the access point goes on hold for at least 60 seconds while the access point passively scans for
another usable channel.

Cisco IP Phone 8861 and 8865 Wireless LAN Deployment Guide
20
TPC allows the client and access point to exchange information, so that the client can dynamically adjust the transmit power.
The client uses only enough energy to maintain association to the access point at a given data rate. As a result, the client
contributes less to adjacent cell interference, which allows for more densely deployed, high-performance wireless LANs.
If there are repeated radar events detected by the access point (just or falsely), determine if the radar signals are impacting a
single channel (narrowband) or multiple channels (wideband), then potentially disable use of that channel or channels in the
wireless LAN.
The presence of an access point on a non-DFS channel can help minimize voice interruptions.
In case of radar activity, have at least one access point per area that uses a non-DFS channel (UNII-1). This ensures that a
channel is available when an access point’s radio is in its hold-off period while scanning for a new usable channel.
A UNII-3 channel (5.745 - 5.825 GHz) can optionally be used if available.
Below is a sample 5 GHz wireless LAN deployment.
For 5 GHz, 25 channels are available in the Americas, 16 channels in Europe, and 19 channels in Japan.
Where UNII-3 is available, it is recommended to use UNII-1, UNII-2, and UNII-3 only to utilize a 12 channel set.
If planning to use UNII-2 extended channels (channels 100 - 144), it is recommended to disable UNII-2 (channels 52-64) on the
access point to avoid having so many channels enabled.
Having many 5 GHz channels enabled in the wireless LAN can delay discovery of new access points.
2.4 GHz (802.11b/g/n)
In general, it is recommended for access points to utilize automatic channel selection instead of manually assigning channels to
access points.
If there is an intermittent interferer, then the access point or access points serving that area may need to have a channel statically
assigned.
In a 2.4 GHz (802.11b/g/n) environment, only non-overlapping channels must be utilized when deploying VoWLAN. Non-
overlapping channels have 22 MHz of separation and are at least 5 channels apart.
There are only 3 non-overlapping channels in the 2.4 GHz frequency range (channels 1, 6, 11).
