Power ReductionYou can reduce the amount of energy that the Cisco IP Phone consumes by using Power Save or EnergyWise(Power Save Plus) mode.

Power Save

In Power Save mode, the backlight on the screen is not lit when the phone is not in use. The phoneremains in Power Save mode for the scheduled duration or until the user lifts the handset or pressesany button.

Set up each phone to enable or disable Power Save settings. You can configure the phones to dim the backlight on a schedule.

Power Save Plus (EnergyWise)

The Cisco IP Phone supports Cisco EnergyWise (Power Save Plus) mode. When your network containsan EnergyWise (EW) controller (for example, a Cisco switch with the EnergyWise feature enabled),you can configure these phones to sleep (power down) and wake (power up) on a schedule to further

reduce power consumption.Set up each phone to enable or disable the EnergyWise settings. If EnergyWise is enabled, configurea sleep and wake time, as well as other parameters. These parameters are sent to the phone as part of the phone configuration XML file.

Power Negotiation over LLDPThe phone and the switch negotiate the power that the phone consumes. Cisco Unified IP Phone 8961, 9951,and 9971 operates at multiple power settings, which lowers power consumption when less power is available.

After a phone reboots, the switch locks to one protocol (CDP or LLDP) for power negotiation. The switchlocks to the first protocol (containing a power Threshold Limit Value [TLV]) that the phone transmits. If thesystem administrator disables that protocol on the phone, the phone cannot power up any accessories becausethe switch does not respond to power requests in the other protocol.

Cisco recommends that Power Negotiation always be enabled (default) when connecting to a switch thatsupports power negotiation.

If Power Negotiation is disabled, the switch may disconnect power to the phone. If the switch does not support power negotiation, disable the Power Negotiation feature before you power up accessories over PoE. Whenthe Power Negotiation feature is disabled, the phone can power the accessories up to the maximum that the

IEEE 802.3af-2003 standard allows.

When CDP and Power Negotiation are disabled, the phone can power the accessories up to 15.4W.Note

Usage notesPurposeNetwork protocol

DHCP is enabled by default. If disabled, you must manuallyconfigure the IP address, subnet

mask, gateway, and a TFTP server on each phone locally.

Cisco recommends that you useDHCP custom option 150. Withthis method, you configure theTFTP server IP address as theoption value. For additionalsupported DHCP configurations,see the “ Dynamic HostConfiguration Protocol ” chapter and the “ Cisco TFTP ” chapter inthe Cisco Unified Communications Manager System Guide .

If you cannot use option150, you may try usingDHCP option 66.

Note

DHCP dynamically allocates and assigns an IP address tonetwork devices.

DHCP enables you to connect an IP phone into the network and the phone to become operational without the need tomanually assign an IP address or to configure additionalnetwork parameters.

Dynamic Host ConfigurationProtocol (DHCP)

Cisco Unified IP Phones use HTTPfor XML services and for troubleshooting purposes.

HTTP is the standard way of transferring information andmoving documents across the Internet and the web.

Hypertext Transfer Protocol(HTTP)

Web applications with both HTTPand HTTPS support have twoURLs configured. Cisco UnifiedIP Phones that support HTTPS

choose the HTTPS URL.

HypertextTransfer Protocol Secure (HTTPS) is a combinationof the HypertextTransfer Protocol with theSSL/TLS protocolto provide encryption and secure identification of servers.

Hypertext Transfer ProtocolSecure (HTTPS)

The Cisco Unified IP Phoneimplements the IEEE 802.1Xstandard by providing support for the following authenticationmethods: EAP-FAST, EAP-TLS,and EAP-MD5.

When 802.1X authentication isenabled on the phone, you shoulddisable the PC port and voiceVLAN.

The IEEE 802.1X standard defines a client-server-basedaccess control and authentication protocol that restrictsunauthorized clients from connecting to a LAN through publicly accessible ports.

Until the client is authenticated, 802.1X access control allowsonly Extensible AuthenticationProtocol over LAN(EAPOL)traffic through the port to which the client is connected. After authentication is successful, normal traffic can pass throughthe port.

IEEE 802.1X

To communicate using IP, network devices must have an assigned IPaddress, subnet, and gateway.

IP addresses, subnets, and gatewayidentifications are automaticallyassigned if you are using the CiscoUnified IP Phone with DynamicHost Configuration Protocol(DHCP). If you are not usingDHCP, you must manually assignthese properties to each phonelocally.

The Cisco Unified IP Phonessupport IPv6 addresses. For moreinformation, see Cisco Unified

Communications Manager Features and Services Guide ,“ Internet Protocol Version 6(IPv6) ” chapter.

IP is a messaging protocol that addresses and sends packetsacross the network.

Internet Protocol (IP)

The Cisco Unified IP Phonesupports LLDP on the PC port.

LLDP is a standardized network discovery protocol (similar to CDP) that is supported on some Cisco and third-partydevices.

Link Layer Discovery Protocol(LLDP)

The Cisco Unified IP Phonesupports LLDP-MED on the SW port to communicate informationsuch as:

• Voice VLAN configuration

• Device discovery

• Power management

• Inventory management

TFTP requires a TFTP server inyour network that theDHCP server can automatically identify. If you

want a phone to use a TFTP server other than the one that the DHCPserver specifies, you mustmanually assign the IP address of the TFTP server by using the Network Configuration menu onthe phone.

For more information, see the“ Cisco TFTP ” chapter in the CiscoUnifiedCommunicationsManager System Guide .

TFTP allows you to transfer files over the network.

On the Cisco Unified IP Phone, TFTP enables you to obtaina configuration file specific to the phone type.

Trivial File Transfer Protocol(TFTP)

UDP is used only for RTP streams.SIP signaling on the phones do notsupport UDP.

UDP is a connectionless messaging protocol for delivery of data packets.

VLAN InteractionThe Cisco Unified IP Phone 8961, 9951, and 9971 contains an internal Ethernet switch, enabling forwardingof packets to the phone, and to the computer (access) port and the network port on the back of the phone.

If a computer is connected to the computer (access) port, the computer and the phone share the same physicallink to the switch andshare the same port on the switch. This shared physical link has the following implicationsfor the VLAN configuration on the network:

• The current VLANs might be configured on an IP subnet basis. However, additional IP addresses mightnot be available to assign the phone to the same subnet as other devices that connect to the same port.

• Data traffic present on the VLAN supporting phones might reduce the quality of VoIP traffic.

• Network security may indicate a need to isolate the VLAN voice traffic from the VLAN data traffic.

You can resolve these issues by isolating the voice traffic onto a separate VLAN. The switch port to whichthe phone connects would be configured for separate VLANs for carrying:

• Shorten the length of the external device cable.

• Apply ferrites or other such devices on the cables for the external device.

Cisco cannot guarantee the performance of external devices, cables, and connectors.

In European Union countries, use only external speakers, microphones, and headsets that are fully compliantwith the EMC Directive [89/336/EC].

Caution

USB Port InformationThe Cisco Unified IP Phone supports a maximum of five devices that connect to each USB port. Each devicethat connects to the phone is included in the maximum device count. For example, your phone can supportfive USB devices (such as three Cisco Unified IP Color Key Expansion modules, one hub, and one other standard USB device) on the side port and five additional standard USB devices on the back port. The Cisco

Unified IP Phone 8961 does not contain a back USB port. Many third-party USB products count as multipleUSB devices; for example, a device containing a USB hub and headset can count as two USB devices. For more information, see the USB device documentation.

Note • Unpowered hubs are not supported, and powered hubs with more than four ports are not supported.

• USB headsets that connect to the phone through a USB hub are not supported.

• The Cisco Unified Video Camera that connects to the phone through a USB hub is not supported.

Phone Configuration FilesConfiguration files for a phone are stored on the TFTP server and define parameters for connecting to CiscoUnified Communications Manager. In general, any time you make a change in CiscoUnified CommunicationsManager that requires the phone to be reset, a change is automatically made to the phone configuration file.

Configuration files also contain information about which image load the phone should be running. If thisimage load differs from the one currently loaded on a phone, the phone contacts the TFTP server to requestthe required load files.

If you configure security-related settings in Cisco Unified Communications Manager Administration, the phone configuration file will contain sensitive information. To ensure the privacy of a configuration file, youmust configure it for encryption. For more information, see the “ Configuring Encrypted Phone ConfigurationFiles ” chapter in Cisco Unified Communications Manager Security Guide . A phone requests a configurationfile whenever it resets and registers with Cisco Unified Communications Manager.

A phone accesses a default configuration file named XmlDefault.cnf.xml from the TFTP server when thefollowing conditions exist:

• You have enabled autoregistration in Cisco Unified Communications Manager

• The phone has not been added to the Cisco Unified Communications Manager database

A Cisco Unified IP Phone, like other network devices, must be configured and managed. These phones encodeG.711 a-law, G.711 mu-law, G.722, G.729a, G.729ab, iLBC, and iSAC codecs, and decode G.711 a-law,G.711 mu-law, G.722, G.729, G.729a, G.729b, G.729ab, iLBC, and iSAC codecs.

Using a cell, mobile, or GSM phone, or two-way radio in close proximity to a Cisco Unified IP Phonemight cause interference. For more information, see the manufacturer ’s documentation of the interferingdevice.

Caution

Cisco Unified IP Phones provide traditional telephony functionality, such as call forwarding and transferring,redialing, speed dialing, conference calling, and voice messaging system access. Cisco Unified IP Phonesalso provide a variety of other features.

As with other network devices, you must configure Cisco Unified IP Phones to prepare them to access CiscoUnified Communications Manager and the rest of the IP network. By using DHCP, you have fewer settingsto configure on a phone. If your network requires it, however, you can manually configure information suchas: an IP address, TFTP server, and subnet information.

Cisco Unified IP Phones can interact with other services and devices on your IP network to provide enhanced

functionality. For example, you can integrate Cisco Unified Communications Manager with the corporateLightweight Directory Access Protocol 3 (LDAP3) standard directory to enable users to search for coworker contact information directly from their IP phones. You can also use XMLto enable users to access informationsuch as weather, stocks, quote of the day, and other web-based information.

Finally, because the Cisco Unified IP Phone is a network device, you can obtain detailed status informationfrom it directly. This information can assist you with troubleshooting any problems users might encounter when using their IP phones. You can also obtain statistics about a current call or firmware versions on the phone.

To function in the IP telephony network, the Cisco Unified IP Phone must connect to a network device, suchas a Cisco Catalyst switch. You must also register the Cisco Unified IP Phone with a Cisco UnifiedCommunications Manager system before sending and receiving calls.

VoIP Wireless Network OverviewThis chapter provides an overview of the interaction between a wireless-capable Cisco Unified IP Phone 9971and other key components of a VoIP network in a wireless localarea network (WLAN) corporate environment.When you deploy a Cisco Unified IP Phone on a wireless LAN, you must use Cisco Unified CommunicationsManager Release 7.1(3) or later and the SIP protocol.

Some networks contain wired components that support wireless components. The wired components includeswitches, routers, and bridges with special modules to enable wireless capability.

The Cisco Unified IP Phone 9971 supports Cisco Centralized Key Management (CCKM), a centralized keymanagement protocol, and provides a cache of session credentials on the wireless domain server (WDS) with802.1x+WEP or WPA(TKIP) only. APs must register to the WDS for fast roaming to work. CCKM is alsosupported on the Cisco Unified Wireless LAN Controller alone. CCKM is not supported with WPA2 or WPA(AES). For details about CCKM, see the Cisco Fast Secure Roaming Application Note at: http://www.cisco.com/en/US/products/hw/wireless/ps4570/prod_technical_reference09186a00801c5223.html .

Administration, to provide wireless voice communication. Cisco Access Points can run in standalone or unifiedmode. Unified mode requires the Cisco Unified Wireless LAN Controller.

The Cisco Unified IP Phone 9971 exhibits Wi-Fi capabilities which can be used with 802.11a, 802.11b, and802.11g Wi-Fi.

The following figure shows a typical WLAN topology that enables the wireless transmission of voice for wireless IP telephony.

Figure 1: WLAN with Wireless IP Phones

Cisco Unified Wireless AP RequirementsAPs are critical components in a WLAN because they provide the wireless links or " hot spots " to the network.When a Cisco Unified IP Phone powers on, it searches for and becomes associated with an access point (AP)

if the phone wireless access is set to On. The Cisco Unified IP Phone scans for APs with SSIDs and encryptiontypes that it recognizes. The phone builds and maintains a list of eligible APs and uses the following variablesto determine the best AP:

• Received Signal Strength Indicator (RSSI): Signal strength of available APs within the RF coveragearea. The phone attempts to associate with the AP with the highest RSSI value and lowest channel usagevalues (QBSS) that possess matching SSID and encryption types.

• Traffic Specification (TSpec): Calculation of call limits and WLAN load balancing. The TSpec valueof each voice stream allows thesystem to allocate bandwidth to voice deviceson a first-come, first-served basis.

APs transmit and receive RF signals over channels within the 2.4 GHz or 5 GHz frequency band. To providea stable wireless environment and reduce channel interference, you must specify nonoverlapping channelsfor each AP. The recommended channels for 802.11b and 802.11g in North America are 1, 6, and 11.

In a non-controller-based wireless network, we recommend that you statically configure channels for eachAP. If your wireless network uses a controller, use the Auto-RF feature for minimal voice disruption.

Cisco Unified IP Phones use the same APs as wireless data devices. However, voice traffic over a WLANrequires different equipment configurations and layouts than a WLAN that is used exclusively for data traffic.Data transmission can tolerate a higher level of RF noise, packet loss, and channel contention than voice

transmission.Packet loss during voice transmission can cause choppy or broken audio and can make the phonecall inaudible. Packet errors can also cause blocky or frozen video.

Because the Cisco Unified IP Phone 9971 is a desktop (not mobile) phone, changes in the local environmentcan cause phones to roam between access points and can affect the voice and video performance. In contrast,data users remain in one place or occasionallymove to another location.Theability to roam while maintaininga call is one of the advantages of wireless voice, so RF coverage needs to include stairwells, elevators, quietcorners outside conference rooms, and passageways.

The Cisco Unified IP Phone 9971 does not support Voice over the Wireless LAN (VoWLAN) via Outdoor MESH technology (Cisco 1500 series).

No support exists for third-party access points because no interoperability testing occurs with these access points. However, if the access point supports the key features and follows the standards, the Cisco UnifiedWireless IP Phone is compliant.

Wi-Fi compliant APs that are manufactured by third-party vendors support the Cisco Unified IP Phone 9971, but mightnot supportkey features such as Wi-Fi MultiMedia (WMM),Unscheduled Auto PowerSave Delivery(U-APSD), Traffic Specification (TSPEC), QoS Basic Service Set (QBSS), Dynamic Transmit Power Control(DTPC), or proxy ARP.

AP Authentication and Encryption Options

Authentication and encryption schemes are set up within the wireless LAN. VLANs are configured in thenetwork and on the APs and specify different combinations of authentication and
