CHAPTER
1
An Overview of the
Cisco Unified IP Phone
The Cisco Unified IP Phones 7906G and 7911G provide voice communication
over an Internet Protocol (IP) network. It functions much like a standard digital
business telephone, allowing you to place and receive phone calls and to access
features such as mute, hold, transfer, and speed dial. In addition, because the
phone is connected to your data network, it offers enhanced productivity features,
including access to network information, XML applications, and customizeable
features.
The Cisco Unified IP Phone, like other network devices, must be configured and
managed. The phone encodes G.711a, G.711µ, G.729a, G.729ab, G.728/iLBC,
and decodes all variants of G.711, G.728/iLBC, and G.729. The phone also
supports wideband (16bits, 16kHz) audio.

What Networking Protocols Are Used?
What Networking Protocols Are Used?
Cisco Unified IP Phones support several industry-standard and Cisco networking
protocols required for voice communication. Tabl e 1 -1 provides an overview of
the supported networking protocols on the Cisco Unified IP Phones 7906G and
7911G.
Table 1-1Supported Networking Protocols on the Cisco Unified IP Phone
Networking ProtocolPurposeUsage Notes
Bootstrap Protocol
(BootP)
Cisco Discovery
Protocol (CDP)
Cisco Peer to Peer
Distribution Protocol
(CPPDP)
BootP enables a network device such
as the Cisco Unified IP Phone to
discover certain startup information,
such as its IP address.
CDP is a device-discovery protocol
that runs on all Cisco-manufactured
equipment.
Using CDP, a device can advertise its
existence to other devices and receive
information about other devices in
the network.
CPPDP is a Cisco proprietary
protocol used to form a peer to peer
hierarchy of devices. CPPDP is also
used to copy firmware or other files
from peer devices to neighboring
devices.
If you are using BootP to assign IP
addresses to the
Cisco Unified IP Phone, the BOOTP
Server option shows “Yes” in the
network configuration settings on the
phone.
The Cisco Unified IP Phone uses
CDP to communicate information
such as auxiliary VLAN ID, per port
power management details, and
Quality of Service (QoS) configuration
information with the Cisco Catalyst
switch.
CPPDP is used by the Peer Firmware
Sharing feature.

Chapter 1 An Overview of the Cisco Unified IP Phone
What Networking Protocols Are Used?
Table 1-1Supported Networking Protocols on the Cisco Unified IP Phone (continued)
Networking ProtocolPurposeUsage Notes
Dynamic Host
Configuration Protocol
(DHCP)
DHCP dynamically allocates and
assigns an IP address to network
devices.
DHCP enables you to connect an IP
phone into the network and have the
phone become operational without
you needing to manually assign an IP
address or to configure additional
network parameters.
HyperText Transfer
Protocol (HTTP)
HTTP is the standard way of
transferring information and moving
documents across the Internet and the
World Wide Web.
IEEE 802.1XThe IEEE 802.1X standard defines a
client-server-based access control
and authentication protocol that
restricts unauthorized clients from
connecting to a LAN through
publicly accessible ports.
Until the client is authenticated,
802.1X access control allows only
Extensible Authentication Protocol
over LAN (EAPOL) traffic through
the port to which the client is
connected. After authentication is
successful, normal traffic can pass
through the port.
DHCP is enabled by default. If
disabled, you must manually
configure the IP address, subnet
mask, gateway, and a TFTP server on
each phone locally.
Cisco recommends that you use
DHCP custom option 150. With this
method, you configure the TFTP
server IP address as the option value.
For additional information about
DHCP configurations, refer to the
“Cisco TFTP” chapter in the
Cisco Unified Communications
Manager System Guide.
The Cisco Unified IP Phones use
HTTP for the XML services and for
troubleshooting purposes.
The Cisco Unified IP Phone
implements the IEEE 802.1X
standard by providing support for the
EAP-MD5 option for 802.1X
authentication.
When 802.1X authentication is
enabled on the phone, you should
disable the PC port and voice VLAN.
See the “Supporting 802.1X
Authentication on Cisco Unified IP
Phones” for additional information.

What Networking Protocols Are Used?
Table 1-1Supported Networking Protocols on the Cisco Unified IP Phone (continued)
Networking ProtocolPurposeUsage Notes
Internet Protocol (IP)IP is a messaging protocol that
addresses and sends packets across
the network.
Real-Time Transport
Protocol (RTP)
RTP is a standard protocol for
transporting real-time data, such as
interactive voice and video, over data
networks.
Real-Time Control
Protocol (RTCP
RTCP works with RTP to provide
QoS data (such as jitter, latency, and
round trip delay) on RTP streams.
To communicate using IP, network
devices must have an assigned IP
address, subnet, and gateway.
IP addresses, subnets, and gateways
identifications are automatically
assigned if you are using the
Cisco Unified IP Phone with
Dynamic Host Configuration
Protocol (DHCP). If you are not
using DHCP, you must manually
assign these properties to each phone
locally.
Cisco Unified IP Phones use the RTP
protocol to send and receive
real-time voice traffic from other
phones and gateways.
RTCP is disabled by default, but you
can enable it on a per phone basis
using
Cisco Unified Communications
Manager. For more information, see
the “Network Configuration” section
on page 4-34.
Secure Real-Time
Transport Protocol
(SRTP)

SRTP is available in addition to RTP.
SRTP adds security by encrypting
media streams during data transport.
Cisco Unified IP Phone 7906G and 7911G for Cisco Unified Communications Manager 6.0
For SRTP to work, the phone or
phones being called must also
support SRTP or else those phones
cannot decrypt the secure media

Networking ProtocolPurposeUsage Notes
Session Initiation
Protocol (SIP)
Skinny Client Control
Protocol (SCCP)
Session Description
Protocol (SDP)
SIP is the Internet Engineering Task
Force (IETF) standard for
multimedia conferencing over IP. SIP
is an ASCII-based application-layer
control protocol (defined in
RFC 3261) that can be used to
establish, maintain, and terminate
calls between two or more endpoints.
SCCP includes a messaging set that
allows communications between call
control servers and endpoint clients
such as IP Phones. SCCP is
proprietary to Cisco Systems.
SDP is the portion of the SIP protocol
that determines which parameters are
available during a connection
between two endpoints. Conferences
are established using only the SDP
capabilities that are supported by all
endpoints in the conference.
Like other VoIP protocols, SIP is
designed to address the functions of
signaling and session management
within a packet telephony network.
Signaling allows call information to
be carried across network
boundaries. Session management
provides the ability to control the
attributes of an end-to-end call.
You can configure the Cisco
Unified IP Phone to use either SIP or
Skinny Client Control Protocol
(SCCP).
Cisco Unified IP Phones use SCCP
for call control. You can configure
the Cisco Unified IP Phone to use
either SCCP or Session Initiation
Protocol (SIP).
SDP capabilities, such as codec
types, DTMF detection, and comfort
noise, are normally configured on a
global basis by Cisco Unified
Communications Manager or Media
Gateway in operation. Some SIP
endpoints may allow these
parameters to be configured on the
endpoint itself.

When security is implemented,
Cisco Unified IP Phones use the TLS
protocol when securely registering
with Cisco Unified Communications
Manager.
TFTP allows you to transfer files
over the network.
On the Cisco Unified IP Phone,
TFTP enables you to obtain a
configuration file specific to the
phone type.
TFTP requires a TFTP server in your
network, which can be automatically
identified from the DHCP server. If
more than one TFTP server is
running in your network, you must
manually assign a TFTP server to
each phone locally.
UDP is a connectionless messaging
protocol for delivery of data packets.

Feature Overview
Cisco Unified IP Phones provide core business features, such as call forwarding
and transferring, redialing, speed dialing, conference calling, and voice
messaging system access. Cisco Unified IP phones also provide a variety of other
features. For an overview of the telephony features that the
Cisco Unified IP Phone supports, see the “Telephony Features Available for the
Cisco Unified IP Phone” section on page 5-2.
As with other network devices, you must configure Cisco Unified IP Phones to
prepare them to access Cisco Unified Communications Manager and the rest of
the IP network. Using DHCP, you have fewer settings to configure on a phone, but
if your network requires it, you can manually configure an IP address, TFTP
server, and subnet mask. For instructions on configuring the network settings on
the Cisco Unified IP Phones, see Chapter 4, “Configuring Settings on the
Cisco Unified IP Phone.”
Chapter 1 An Overview of the Cisco Unified IP Phone
The Cisco Unified IP Phone can interact with other services and devices on your
IP network to provide enhanced functionality. For example, you can integrate the
Cisco Unified IP Phones with the corporate Lightweight Directory Access
Protocol 3 (LDAP3) standard directory to enable users to search for co-workers
contact information directly from their IP phones. Or, you can also use XML to
enable users to access information such as weather, stocks, quote of the day, and
other web-based information. For information about configuring such services,
see the “Configuring Corporate and Personal Directories” section on page 5-23
and the “Setting Up Services” section on page 5-25.
Finally, because the Cisco Unified IP Phone is a network device, you can obtain
detailed status information from it directly. This information can assist you with
troubleshooting any problems users might encounter when using their IP phones.

administrators to provide, see Appendix A, “Providing Information to Users.”
Understanding Security Features for Cisco Unified IP
Phones
Implementing security in the Cisco Unified Communications Manager system
prevents identity theft of the phone and Cisco Unified Communications Manager
server, prevents data tampering, and prevents call signaling and media stream
tampering.
To alleviate these threats, the Cisco Unified Communications network establishes
and maintains authenticated and encrypted communication streams between a
phone and the server, digitally signs files before they are transferred to a phone
and encrypts media streams between Cisco Unified IP phones.
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, you must configure it

FeatureDescription
Customer-site certificate installationEach Cisco Unified IP Phone requires a unique certificate for
device authentication. Phones include a manufacturing
installed certificate (MIC), but for additional security, you
can specify in Cisco Unified Communications Manager
Administration that a certificate be installed by using the
Certificate Authority Proxy Function (CAPF). Alternatively,
you can install an Locally Significant Certificate (LSC) from
the Security Configuration menu on the phone. See the
“Configuring Security on the Cisco Unified IP Phone”
section on page 3-17 for more information.
Device authenticationOccurs between the Cisco Unified Communications Manager
server and the phone when each entity accepts the certificate
of the other entity. Determines whether a secure connection
between the phone and a Cisco Unified Communications
Manager should occur, and, if necessary, creates a secure
signaling path between the entities using TLS protocol.
Cisco Unified Communications Manager does not register
phones configured in authenticated or encrypted mode unless
they can be authenticated by the
Cisco Unified Communications Manager.
File authenticationValidates digitally-signed files that the phone downloads.
The phone validates the signature to make sure that file
tampering did not occur after the file creation. Files that fail
authentication are not written to Flash memory on the phone.
The phone rejects such files without further processing.
Signaling AuthenticationUses the TLS protocol to validate that no tampering has
occurred to signaling packets during transmission.
Manufacturing installed certificateEach Cisco Unified IP Phones 7906G and 7911G contains a
unique MIC, which is used for device authentication. The
MIC is a permanent unique proof of identity for the phone,
and allows Cisco Unified Communications Manager to
authenticate the phone.

Secure SRST reference
(SCCP phones only)
After you configure a SRST reference for security and then
reset the dependent devices in Cisco Unified
Communications Manager Administration, the TFTP server
adds the SRST certificate to the phone cnf.xml file and sends
the file to the phone. A secure phone then uses a TLS
connection to interact with the SRST-enabled router.
Media encryptionUses SRTP to ensure that the media streams between
supported devices proves secure and that only the intended
device receives and reads the data. Includes creating a media
master key pair for the devices, delivering the keys to the
devices, and securing the delivery of the keys while the keys
are in transport.
Signaling Encryption
(SCCP phones only)
Ensures that all SCCP signaling messages that are sent
between the device and the Cisco Unified Communications
Manager server are encrypted.
CAPF (Certificate Authority Proxy
Function)
Implements parts of the certificate generation procedure that
are too processing-intensive for the phone, and it interacts
with the phone for key generation and certificate installation.
The CAPF can be configured to request certificates from
customer-specified certificate authorities on behalf of the
phone, or it can be configured to generate certificates locally.

Identifying Encrypted and Authenticated Phone Calls
When security is implemented for a phone, you can identify authenticated or
encrypted phone calls by icons on the LCD screen on the phone.
In an authenticated call, all devices participating in the establishment of the call
are authenticated by the Cisco Unified Communications Manager. When a call in
progress is authenticated end-to-end, the call progress icon to the right of the call
duration timer in the phone LCD screen changes to the following icon:
In an encrypted call, all devices participating in the establishment of the call are
authenticated by the Cisco Unified Communications Manager. In addition, call
signaling and media streams are encrypted. An encrypted call offers the highest
level of security, providing integrity and privacy to the call. When a call in
progress is being encrypted, the call progress icon to the right of the call duration
timer in the phone LCD screen changes to the following icon:

Establishing and Identifying Secure Conference Calls
You can initiate a secure conference call and monitor the security level of
participants. A secure conference call is established using this process:
1.A user initiates the conference from a secure phone (encrypted or
authenticated security mode).
2.Cisco Unified Communications Manager assigns a secure conference bridge
to the call.
3.As participants are added, Cisco Unified Communications Manager verifies
the security mode of each phone (encrypted or authenticated) and maintains
the secure level for the conference.
4.The phone displays the security level of the conference call. A secure
conference displays
(encrypted) or ( authenticated) icon to the
right of “Conference” on the phone screen. If icon displays, the
conference is not secure.
NoteThere are interactions, restrictions, and limitations that affect the security level of
the conference call depending on the security mode of the participant’s phones
and the availability of secure conference bridges. See Tab le 1- 4 and Ta ble 1 -5 for
information about these interactions.

Supporting 802.1X Authentication on Cisco Unified IP Phones
These sections provide information about 802.1X support on the Cisco Unified IP
Phones:
•Overview, page 1-23
•Required Network Components, page 1-24
•Best Practices—Requirements and Recommendations, page 1-24
Overview
Cisco Unified IP phones and Cisco Catalyst switches have traditionally used
Cisco Discovery Protocol (CDP) to identify each other and to determine
parameters such as VLAN allocation and inline power requirements. However,
CDP is not used to identify any locally attached PCs. Therefore, Cisco Unified IP
Phones provide an EAPOL pass-through mechanism, whereby a PC locally
attached to the IP phone may pass through EAPOL messages to the 802.1X
authenticator in the LAN switch. This capability prevents the IP phone from
having to act as the authenticator, yet allows the LAN switch to authenticate a data
end point prior to accessing the network.
In conjunction with the EAPOL pass-through mechanism, Cisco Unified IP
Phones provide a proxy EAPOL-Logoff mechanism. If the locally attached PC is
disconnected from the IP phone, the LAN switch would not see the physical link
fail, because the link between the LAN switch and the IP phone is maintained. To
avoid compromising network integrity, the IP phone sends an EAPOL-Logoff
message to the switch on behalf of the downstream PC, which triggers the LAN
switch to clear the authentication entry for the downstream PC.
The Cisco Unified IP phones contain an 802.1X supplicant in addition to the
EAPOL pass-through mechanism. This supplicant allows network administrators
to control the connectivity of IP phones to the LAN switch ports. The initial
release of the IP phone 802.1X supplicant implements the EAP-MD5 option for
802.1X authentication.

Understanding Security Features for Cisco Unified IP Phones
Required Network Components
Support for 802.1X authentication on Cisco Unified IP Phones requires several
components, including:
•Cisco Unified IP Phone—The phone acts as the 802.1X supplicant, which
initiates the request to access the network.
•Cisco Secure Access Control Server (ACS) (or other third-party
authentication server)—The authentication server and the phone must both be
configured with a shared secret that is used to authenticate the phone.
•Cisco Catalyst Switch (or other third-party switch)—The switch must support
802.1X so it can act as the authenticator and pass the messages between the
phone and the authentication server. When the exchange is completed, the
switch grants or denies the phone access to the network.
Chapter 1 An Overview of the Cisco Unified IP Phone
Best Practices—Requirements and Recommendations
•Enable 802.1X Authentication—If you want to use the 802.1X standard to
authenticate Cisco Unified IP Phones, make sure that you have properly
configured the other components before enabling it on the phone. See the
“802.1X Authentication and Status” section on page 4-43 for more
information.
•Configure PC Port—The 802.1X standard does not take into account the use
of VLANs and thus recommends that only a single device be authenticated to
a specific switch port. However, some switches (including Cisco Catalyst
switches) support multi-domain authentication. The switch configuration
determines whether you can connect a PC to the phone PC port.
–
Enabled—If you are using a switch that supports multi-domain
authentication, you can enable the PC port and connect a PC to it. In this
case, Cisco Unified IP Phones support proxy EAPOL-Logoff to monitor
the authentication exchanges between the switch and the attached PC.
For more information about IEEE 802.1X support on the Cisco Catalyst
switches, refer to the Cisco Catalyst switch configuration guides at:
Disabled—If the switch does not support multiple 802.1X-compliant
devices on the same port, you should disable the PC Port when 802.1X
authentication is enabled. See the “Security Configuration Menu” section

authentication, you can continue to use the voice VLAN.
–
Disabled—If the switch does not support multi-domain authentication,
disable the Voice VLAN and consider assigning the port to the native
VLAN. See the “Security Configuration Menu” section on page 4-32 for
more information.
•Enter MD5 Shared Secret—If you disable 802.1X authentication or perform
a factory reset on the phone, the previously configured MD5 shared secret is
deleted. See the “802.1X Authentication and Status” section on page 4-43 for
more information.
Understanding Security Features for Cisco Unified IP Phones
Security Restrictions
A user cannot barge into an encrypted call if the phone that is used to barge is not
configured for encryption. When barge fails in this case, a reorder tone (fast busy
tone) plays on the barge initiator's phone.
If the initiator phone is configured for encryption, the barge initiator can barge
into an authenticated or nonsecure call from the encrypted phone. After the barge
occurs, Cisco Unified Communications Manager classifies the call as nonsecure.
If the initiator phone is configured for encryption, the barge initiator can barge
into an encrypted call, and the phone indicates that the call is encrypted.
A user can barge into an authenticated call, even if the phone that is used to barge
is nonsecure. The authentication icon continues to appear on the authenticated
devices in the call, even if the initiator phone does not support security.

Preparing to Install the
Cisco Unified IP Phone on Your
Network
Cisco Unified IP Phones enable you to communicate using voice over a data
network. To provide this capability, the IP Phones depend upon and interact with
several other key Cisco Unified Communications and network components,
including Cisco Unified Communications Manager, DNS and DHCP servers,
TFTP servers, and media resources.
This chapter provides an overview of the interaction between the Cisco Unified IP
Phones 7906G and 7911G and other key components of the Voice-over-IP (VoIP)
network, and focuses on the interactions between the Cisco Unified IP
Phones 7906G and 7911G and Cisco Unified Communications Manager, TFTP
server, and switches. It includes these topics:

Understanding Interactions with Other
Cisco Unified Communications Products
To function in the Unified Communications network, the Cisco Unified IP Phone
must be connected to a networking device, such as a Cisco Catalyst switch. You
must also register the Cisco Unified IP Phone with a
Cisco Unified Communications Manager system before sending and receiving
calls.

Understanding How the Cisco Unified IP Phone Interacts with
Cisco Unified Communications Manager
Cisco Unified Communications Manager is an open and industry-standard call
processing system. Cisco Unified Communications Manager software sets up and
tears down calls between phones, integrating traditional PBX functionality with
the corporate IP network. Cisco Unified Communications Manager manages the
components of the Cisco Unified Communications system—the phones, the
access gateways, and the resources necessary for such features as call
conferencing and route planning. Cisco Unified Communications Manager also
provides authentication and encryption if configured for the communications
system.
For information about configuring Cisco Unified Communications Manager to
work with the IP devices described in this chapter, refer to
Cisco Unified Communications Manager Administration Guide, Cisco Unified
Communications Manager System Guide, and to Cisco Unified Communications
Manager Security Guide.
For an overview of security functionality for the Cisco Unified IP Phone, see the
“Understanding Security Features for Cisco Unified IP Phones” section on

Administration, go to the following URL and install the latest support patch for
your version of Cisco Unified Communications Manager:
•Telephony Features Available for the Cisco Unified IP Phone, page 5-2
Understanding How the Cisco Unified IP Phone Interacts with the
VLAN
The Cisco Unified IP Phone 7911G has an internal Ethernet switch, which enables
forwarding of packets to the phone and to the network port and access port on the
back of the phone. The Cisco Unified IP Phone 7906G has an Ethernet port, which
enables forwarding of packets to the phone and to the network port.
If a computer is connected to the access port (Cisco Unified IP Phone 7911G), the
computer and the phone share the same physical link to the switch and the same
port on the switch. This shared physical link affects the VLAN configuration on
the network in the following ways:
•Although current VLANs might be configured on an IP subnet basis,
additional IP addresses may not be available to assign the phone to the same
subnet as other devices that connect to the same port.
•Data traffic present on the data/native VLAN may reduce the quality of
Voice-over-IP traffic.
•Network security may necessitate the isolation of the VLAN voice traffic
from the VLAN data traffic.
You can resolve these issues by isolating the voice traffic onto a separate VLAN,
so that the switch port to which the phone is connected uses separate VLANs for
the following types of traffic:
•Voice traffic to and from the IP phone (auxiliary VLAN, on the
Cisco Catalyst 6000 series, for example)

Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network
Providing Power to the Cisco Unified IP Phones 7906G and 7911G
•Data traffic to and from the PC connected to the switch through the access
port of the IP phone (native VLAN, 7911G only)
Isolating the phones on a separate, auxiliary VLAN improves the quality of the
voice traffic and allows a large number of phones to be added to an existing
network in which there are not enough IP addresses for each phone.
For more information, refer to the documentation included with a Cisco switch.
You can also access related documentation at this URL:

Power Outage
The Cisco Unified IP Phone Series use the CP-PWR-CUBE-3 power
supply.
The Cisco Unified IP Phone Power Injector may be used with any
Cisco Unified IP Phone. Functioning as a midspan device, the injector
delivers inline power to the attached phone. The Cisco Unified IP Phone
Power Injector is connected between a switch port and the IP Phone, and
supports a maximum cable length of 100m between the unpowered switch
and the phone.
•The Cisco Unified IP Phones 7906G and 7911G support both Cisco
inline power and IEEE 802.3af Power over Ethernet.
•To ensure uninterruptible operation of the phone, make sure that the
switch has a backup power supply.
•Make sure that the CatOS or IOS version running on your switch
supports your intended phone deployment. Refer to the documentation
for your switch for operating system version information.
Your accessibility to emergency service through the phone is dependent on the
phone being powered. If there is an interruption in the power supply, Service and
Emergency Calling Service dialing will not function until power is restored. In the
case of a power failure or disruption, you may need to reset or reconfigure
equipment before using the Service or Emergency Calling Service dialing.

Understanding Phone Configuration Files
Understanding Phone Configuration Files
Configuration files for a phone are stored on the TFTP server and define
parameters for connecting to Cisco Unified Communications Manager. In
general, any time you make a change in Cisco Unified Communications Manager
that requires the phone to be reset, a change is made to the phone’s configuration
file automatically.
Configuration files also contain information about which image load the phone
should be running. If this image load differs from the one currently loaded on a
phone, the phone contacts the TFTP server to request the required load files.
These files are digitally signed to ensure the authenticity of the files’ source.
In addition, if the device security mode in the configuration file is set to
Authenticated and the CTL file on the phone has a valid certificate for
Cisco Unified Communications Manager, the phone establishes a TLS connection
to Cisco Unified Communications Manager. Otherwise, the phone establishes a
TCP connection.
NoteIf the device security mode in the configuration file is set to Authenticated or
Encrypted but the phone has not received a CTL file, the phone will continuously
try to obtain a CTL file so that it can register securely.
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, you must configure it
for encryption. For detailed information, refer to the “Configuring Encrypted
Phone Configuration Files” chapter in Cisco Unified Communications Manager Security Guide.
A phone requests a configuration file 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 these conditions exist:
•You have enabled auto-registration in Cisco Unified Communications
Manager
•The phone has not been added to the Cisco Unified Communications
Manager Database
•The phone is registering for the first time
Cisco Unified IP Phone 7906G and 7911G for Cisco Unified Communications Manager 6.0
OL11954-01
2-7
Page 62
Understanding the Phone Startup Process
If auto registration is not enabled and the phone has not been added to the
Cisco Unified Communications Manager Database, the phone registration request
will be rejected. In this case, the phone will reset and attempt to register
repeatedly.
If the phone has registered before, the phone will access the configuration file
named SEPmac_address.cnf.xml, where mac_address is the MAC address of the
phone. For more information about how the phone interacts with the TFTP server,
refer to Cisco Unified Communications Manager System Guide, “Cisco TFTP”
chapter.
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, you must configure it
for encryption. For more information, refer to the “Configuring Encrypted Phone
Configuration Files” chapter in Cisco Unified Communications Manager Security Guide.
Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network
SIP Dial Rules
For Cisco Unified IP Phones running under SIP, the administrator uses dial rules
to configure SIP phone dial plans. These dial plans must be associated with a SIP
phone device to enable dial plans to be sent to the configuration file. If the
administrator does not configure a SIP phone dial plan, the phone does not display
any indication of a dial plan. In this case, you must press the Dial softkey, unless
the phone supports key press markup language (KPML).
For more information on configuring SIP dial rules, refer to the
Cisco Unified Communications Manager Administration Guide.
Understanding the Phone Startup Process
When connecting to the VoIP network, the Cisco IP Phone goes through a
standard startup process, as described in Ta ble 2 -3. Depending on your specific
network configuration, not all of these steps may occur on your
Cisco Unified IP Phone.

StepDescriptionRelated Topics
1.Obtaining Power
from the Switch.
2.Loading the Stored
Phone Image.
3.Configuring
VLAN.
If a phone is not using external power, the switch
provides in-line power through the Ethernet cable
attached to the phone.
The Cisco IP Phone has non-volatile Flash
memory in which it stores firmware images and
user-defined preferences. At startup, the phone
runs a bootstrap loader that loads a phone image
stored in Flash memory. Using this image, the
phone initializes its software and hardware.
If the Cisco IP Phone is connected to a Cisco
switch, the switch next informs the phone of the
voice VLAN defined on the switch port. The
phone needs to know its VLAN membership
before it can proceed with the Dynamic Host
Configuration Protocol (DHCP) request for an IP
address.
See the “Providing
Power to the
Cisco Unified IP Phone
s 7906G and 7911G”
section on page 2-4.

section on page 9-2.
If a third-party switch is used and VLANs are
configured, the VLAN on the phone must be
manually configured.
4.Obtaining an IP
Address.
If the Cisco IP Phone is using DHCP to obtain an
IP address, the phone queries the DHCP server to
obtain one. If you are not using DHCP in your
network, you must assign static IP addresses to
each phone locally.

5.Accessing a TFTP
Server.
6.Requesting the
CTL file.
In addition to assigning an IP address, the DHCP
server directs the Cisco Unified IP Phone to a
TFTP Server. If the phone has a statically-defined
IP address, you must configure the TFTP server
locally on the phone; the phone then contacts the
TFTP server directly.
NoteYou can also assign an alternative TFTP
server to use instead of the one assigned by
DHCP.
The TFTP server stores the certificate trust list
(CTL) file. This file contains a list of
Cisco Unified Communications Managers and
TFTP servers that the phone is authorized to
connect to. It also contains the certificates
necessary for establishing a secure connection
between the phone and
Cisco Unified Communications Manager.

8.Contacting
Cisco Unified

Manager.
The TFTP server has configuration files, which
define parameters for connecting to
Cisco Unified Communications Manager and
other information for the phone.
The configuration file defines how the
Cisco Unified IP Phone communicates with
Cisco Unified Communications Manager and
provides a phone with its load ID. After obtaining
the file from the TFTP server, the phone attempts
to make a connection to the highest priority
Cisco Unified Communications Manager on the
list. If security is implemented, the phone makes a
TLS connection. Otherwise, it makes a non-secure
TCP connection.
If the phone was manually added to the database,
Cisco Unified Communications Manager
identifies the phone. If the phone was not
manually added to the database and
auto-registration is enabled in
Cisco Unified Communications Manager, the
phone attempts to auto-register itself in the
Cisco Unified Communications Manager
database.

Adding Phones with Auto-Registration
By enabling auto-registration before you begin installing phones, you can:
•Add phones without first gathering MAC addresses from the phones.
•Automatically add a Cisco Unified IP Phone to the Cisco Unified
Communications Manager database when you physically connect the phone
to your IP telephony network. During auto-registration, Cisco Unified
Communications Manager assigns the next available sequential directory
number to the phone.
individually
•Can add groups of same model of
phone.
•Can schedule when phones are
added to the
Cisco Unified Communications
Manager database.
•Quickly enter phones into the Cisco Unified Communications Manager
database and modify any settings, such as the directory numbers, from
Cisco Unified Communications Manager.
•Move auto-registered phones to new locations and assign them to different
device pools without affecting their directory numbers.

Adding Phones to the Cisco Unified Communications Manager Database
NoteCisco recommends you use auto-registration to add less than 100 phones to your
network. To add more than 100 phones to your network, use the Bulk
Administration Tool (BAT). See the “Adding Phones with BAT” section on
page 2-16.
Auto-registration is disabled by default. In some cases, you might not want to use
auto-registration: for example, if you want to assign a specific directory number
to the phone or if you plan to implement authentication or encryption, as
described in Cisco Unified Communications Manager Security Guide. For
information about enabling auto-registration, refer to “Enabling
Auto-Registration” in the Cisco Unified Communications Manager Administration Guide.
NoteWhen you configure the cluster for mixed mode through the Cisco CTL client,
auto-registration is automatically disabled. When you configure the cluster for
non-secure mode through the Cisco CTL client, auto-registration is automatically
enabled.

Adding Phones with Auto-Registration and TAPS
You can add phones with auto-registration and TAPS, the Tool for
Auto-Registered Phones Support, without first gathering MAC addresses from
phones.
TAPS works with the Bulk Administration Tool (BAT) to update a batch of phones
that were already added to the Cisco Unified Communications Manager database
with dummy MAC addresses. Use TAPS to update MAC addresses and download
pre-defined configurations for phones.

To implement TAPS, you or the end-user dial a TAPS directory number and follow
voice prompts. When the process is complete, the phone will have downloaded its
directory number and other settings, and the phone will be updated in
Cisco Unified Communications Manager Administration with the correct MAC
address.
Auto-registration must be enabled in Cisco Unified Communications Manager
Administration (System > Cisco Communications Manager) for TAPS to
function.
NoteWhen you configure the cluster for mixed mode through the Cisco CTL client,
auto-registration is automatically disabled. When you configure the cluster for
non-secure mode through the Cisco CTL client, auto-registration is automatically
enabled.

Chapter 3 Setting Up the Cisco Unified IP Phone
Headset
Although Cisco Systems performs some internal testing of third-party headsets
for use with the Cisco Unified IP Phones, Cisco does not certify or support
products from headset or handset vendors. Because of the inherent environmental
and hardware inconsistencies in the locations where Cisco Unified IP Phones are
deployed, there is not a single “best” solution that is optimal for all environments.
Cisco recommends that customers test the headsets that work best in their
environment before deploying a large number of units in their network.
In some instances, the mechanics or electronics of various headsets can cause
remote parties to hear an echo of their own voice when they speak to
Cisco Unified IP Phone users.
Cisco Systems recommends the use of good quality external devices, like headsets
that are screened against unwanted radio frequency (RF) and audio frequency
(AF) signals. Depending on the quality of these devices and their proximity to
other devices such as cell phones and two-way radios, some audio noise may still
occur.

OL11954-01
Page 81
Chapter 3 Setting Up the Cisco Unified IP Phone
The primary reason that support of a headset would be inappropriate for an
installation is the potential for an audible hum. This hum can either be heard by
the remote party or by both the remote party and the Cisco Unified IP Phone user.
Some potential humming or buzzing sounds can be caused by a range of outside
sources, for example, electric lights, being near electric motors, large PC
monitors. In some cases, a hum experienced by a user may be reduced or
eliminated by using the Cisco Unified IP Phone Power Cube 3
(CP-PWR-CUBE-3).
Audio Quality Subjective to User
Beyond the physical, mechanical and technical performance, the audio portion of
a headset must sound good to the user and the party on the far end. Sound is
subjective and Cisco cannot guarantee the performance of any headsets or
handsets, but some of the headsets and handsets on the sites listed below have
been reported to perform well on Cisco Unified IP Phones.
Understanding the Cisco Unified IP Phones 7906G and 7911G Components
Nevertheless, it is ultimately still the customer’s responsibility to test this
equipment in their own environment to determine suitable performance.
For information about headsets, see:
http://www.vxicorp.com/cisco
http://www.plantronics.com/cisco
http://www.jabra.com
Connecting a Headset
To connect a headset to the Cisco Unified IP Phone, plug it into the RJ-9 Handset
port on the back of the phone. Depending on headset manufacturer’s
recommendations, an external amplifier may be required. Refer to headset
manufacturer's product documentation for details.
You can use the headset with all of the features on the Cisco Unified IP Phone,
including using the Volume button.

Using External Devices with Your Cisco Unified IP Phone
The following information applies when you use external devices with the
Cisco Unified IP Phone:
Cisco recommends the use of good quality external devices (headsets) that are
shielded (screened) against unwanted radio frequency (RF) and audio frequency
(AF) signals.
Depending on the quality of these devices and their proximity to other devices
such as mobile phones or two-way radios, some audio noise may still occur. In
these cases, Cisco recommends that you take one or more of the following actions:
•Move the external device away from the source of the RF or AF signals.
•Route the external device cables away from the source of the RF or AF
signals.
•Use shielded cables for the external device, or use cables with a better shield
and connector.
•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 the system because Cisco has no
control over the quality of external devices, cables, and connectors. The system
will perform adequately when suitable devices are attached using good quality
cables and connectors.
CautionIn European Union countries, use only external headsets that are fully compliant
with the EMC Directive [89/336/EC].

Configuring Security on the Cisco Unified IP Phone
The security features protect against several threats, including threats to the
identity of the phone and to data. These features establish and maintain
authenticated communication streams between the phone and the
Cisco Unified Communications Manager server, and digitally sign files before
they are delivered.
For more information about the security features, see the “Understanding Security
Features for Cisco Unified IP Phones” section on page 1-12. Also, refer to
A Locally Significant Certificate (LSC) installs on phones after you perform the
necessary tasks that are associated with the CAPF. You can use
Cisco Unified Communications Manager Administration to configure an LSC, as
described in Cisco Unified Communications Manager Security Guide.
Alternatively, you can install an LSC from the Security Configuration menu on
the phone. This menu also lets you update or remove an LSC.
