What Networking Protocols Are Used?

What Networking Protocols Are Used?

Cisco IP Phones support several industry- st anda rd an d Cisco net working
protocols for voice commu nica tion. Table 1-1 provides an overview of the
networking protocols that the Cisco IP Phon e mode ls 7902G/790 5G/791 2G
supports.

Table 1-1 Supported Networking Protocols on the Cisco IP Phone

Networking Prot ocol Pur pose Usage Notes

Cisco D is cove ry
Protocol (CDP)

Dynamic Host
Configuration Protocol
(DHCP)

CDP is a device-discovery protoc ol t hat
runs on all Cisc o-m anufac tur ed
equipment.

Using CDP, a device can advertise its
existence to other devices and receive
information ab out o the r d evices in th e
network.

DHCP dynamically allocates and assigns
an IP address to network devices.

DHCP enable s you to co nnec t an IP
phone into the net work and have the
phone become ope rationa l without you
needing to manually assign an IP ad dress
or configure additio nal net work
parameters.

The Cisco 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.

DHCP is enabled by default. If
disabled, you mu st ma nu ally
configure the IP ad dress, subn et
mask, gateway, and an TFTP
server on each ph one lo ca ll y.

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
supported DCHP configurations,
see Cisco CallManager System
Guide.

What Networking Protocol s Are Used?

Table 1-1 Supported Networking Protocols on the Cisco IP Phone (continued)

Networking Prot ocol Pur pose Usage Notes

Internet Protocol (IP) IP is a messaging protocol that addresses

and sends packets across the network.

Real-Time Transport
(RTP)

RTP is a standard for transporting
real-time data, such as interactive voice
and video, over data networks.

Transmission Control
Protocol (TCP)

Trivial File Transfer
Protocol (TFTP)

TCP is a a connection-oriented transport
protocol.

TFTP allows you to transfer f iles ov er the
network.

On the Cisc o IP Phone, TFTP en ab les
you to obtain a conf iguration fi le spec if ic
to the phone type .

User Datagram Protocol
(UDP)

UDP is a connectionless mess aging
protocol for delivery of data packets.

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

IP addresses, subnets, and
gateways identifications are
automatically a ssigned if you ar e
using the Cisco 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 IP Phones use the RTP
protocol to send and receive
real-time voice traffic from other
phones and gateways.

Cisco IP Phones use TCP to
connect to Cisco CallManager
and to access XML services.

TFTP requires a TFTP server in
your network, which c an be
automatically identif ied from the
DHCP server. If more than one
TFTP server is runnin g in yo ur
network, you must manuall y
assign a TFTP server to each
phone locally.

Cisco IP Phones receive and
process UDP messages.

Feature Overview

Cisco IP Phones provide traditional telephony functionality, such as call
forwarding and tra nsf er ring, r edi ali ng , spe ed di al ing, c onf eren ce ca llin g, an d
voice messaging system access. Cisco IP phones also provide a variety of other
features. For an overview telephony features the Cisco IP Phone models

section on page 5-2.

Like other network devices, you must configure the Cisco IP Phon es to prepare
them to access Cisco CallManager and the rest of the IP network. Using DHCP,
you have fewer settings to modify, but you can choose to assign a static IP if your
network requires it. For instructions on configuring the network sett ings on the
Cisco IP Phones, see Chapte r 4, “C onfiguring Network Set tings on the

Cisco IP Phone.”

Understanding How the Cisco IP Phone Interacts with
Cisco CallManager

Cisco CallManager is an open and indust ry-stand ard cal l processing system.
Cisco CallManager software runs on a Windows 2000 server and sets up and tears
down calls between phones, integrating traditional PBX functionality with the
corporate IP network. Cisco CallManager manages the components of the IP
telephony system—the phones, access gateways, and the resources necessary for
such features as call co nfere ncing a nd route pl anning .

For information about configuring Cisco CallManager to work with the I P devices
described in this chapter, refer to Cisco CallManager Administration Guide and

Cisco CallManager System Guide.

Understanding Interactions with Other Cisco IP Telephony Products

Understanding How the Cisco IP Phone Interacts with the
Cisco Catalyst Family of Switches

The Cisco IP Phone 7912G has an inte rn al Ethe rn et sw itch, enabl ing it to switch
incoming traffic to the phone, the access port, or to the network port (see the

“Connecting to the Network” section on page 2-8 for details). The Cisco IP Phone

models 7902G/7905G do not include an internal Ethernet switch or an access port.
If a computer is connected to the access port, the computer and the phone share

the same physical link to the switch and the same port on the switch.
This shared physical link has the foll owing implicati ons for the VLAN

configuration on the n etwor k:

• The current VLANs mi ght be configure d on an IP subnet ba sis. However,

additional IP addre sses may not be available to assign the phone to the same
subnet as other devices connected t o the same port .

• Data traff ic present on the VLAN suppor ting phones might reduce the quality

of Voice-over-IP traffic.

You can resolve these issues by isolating the voice traffic onto a separate VLAN
on each of the ports connecte d to a phone. The switch port configure d for
connecting a phone wou ld have separate VLAN s configured for carr ying:

OL-6313-01

• Voice tra ffic to and from the IP phone (a uxiliary VLAN)

• Data traffic to and from the PC connected to the switch through the access

port of the IP p hon e (n ative VLAN )

Isolating the phones on a separate, auxiliary VLAN increases the quality of the
voice traffic and allows a large number of phones to be added to an existing
network where the r e ar e not en oug h I P a dd resses.

For more information, refer to the documentation included with the
Cisco C atalyst switch.

Understanding the Phone Startup Process

Understanding the Phone Startup Process

When connecting t o t he VoIP network, the Cisco IP Phone go es thro ugh a
standard startup pro cess co mpos ed of u p to seven steps. De pendi ng on y our
specific network configuration, not all of the se step s may occur on yo ur
Cisco IP Phone.

Each of these steps is described in the sections that follow:

• Obtaining Power from the Swit ch, page 2- 4

• Loading the St ored Phon e Imag e, p age 2-5

• Configuring VLAN, page 2-5

• Obtaining an IP Address, pag e 2-5

Obtaining Power from the Switch

You can connect the Cisco IP Phone to a Cisco Catalyst switch with on e of the
modules that provid es power to t he p hon e (W S-X634 8-R J45V ) . See the

“Providing Power to the Ci sco I P Pho ne” se ction on pa ge 2 -9 fo r details .

If you use this opti onal co nfigura ti on, t he p hon e rece ives phan tom power an d
powers up when you connect the Cisco IP Phone t o the switc h. The phone then
sends Cisco Discovery Protocol (CDP) notifications to the switch indicating it is
ready to receive CDP packets and indicating the power requirement for the phone.
The switch allocates power an d sends it over the network cabl e.

Accessing TFTP Server

In addition to assigning an IP addr ess, the DHCP server dire cts the
Cisco 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.

Requesting Configuration Files

The TFTP server ha s co nfigura tion files ( .cnf file for ma t o r . cnf. xm l) f or
telephony devices, which define parameters for connecting to Cisco CallManager.
In general, any t ime you ma ke a chan ge in Ci sco C al lM an ager t hat requ i res the
phone (device) to be re set, a cha nge has b ee n ma de to the p hone' s con figurat ion
file.

The .cnf.xml file also contains the information that tells the phone which image
load it should be running. If this image load differs from the one currently loaded
on the phone, the phone cont acts th e TFTP server to re quest the new image file.

The phone first requests the file SEPxxxxxxxxxxxx.cnf.xml, where each xx is the
two-digit lowercase hexadecimal representation of each integer in the phone’s
MAC address. If the phone cannot find this file, it requests th e files
XMLDefault.cnf.xm l and SEDDefa ult.cnf.

After the phone ob tains one of t he .c nf .xml files or t he . c nf file, the
Cisco IP Phone 7902G request s the profile file ffxxxxxxxxxxxx, the
Cisco IP Phone 7905G requests th e profile file ldxxxxxxxxxxxx, and the
Cisco IP Phone 7912G requests the profile file gkxxxxxxxxxxxx, where each xx is

Connecting to the Network

The Cisco IP Phone 7912G has two RJ-45 ports labelled “network” and “access.”
The Cisco IP Phone m odels 7 902G/7 905G have one RJ- 45 por t. Ea ch p ort
supports 10/100 Mbps half - or full-dup lex connect ions to exter nal devices. You
can use either Category 3 or 5 cabling for 10-Mbps connections, but you must use
Category 5 for 100 Mbps conne ct ions. On both the network port and access port,
use full-duplex mode to avoid collisions.

See Figure 3-1 for the connec tion por ts available on the back of the Ci sco IP
Phone models 7902G/7905G. See Figure 3-2 for the connectio n ports a vail able on

Providing Power to the Cisco IP Phone

You can power a Cisco IP Phone f rom a n extern al p ower suppl y, from a switch
port, or from a power source between the pho ne and the swit ch.

The Cisco IP Phone can b e powered by the following sources :

OL-6313-01

• External power—optiona l Cisco AC adapter and power cord fo r conne cting

to a standard wall receptacle.

• Inline power—inline power pr ovider to th e Cisco IP Phone when co nne cte d

to a Cisco Catalyst switch capable of providing inline power.

Note Only the network port supports in line power from the

Cisco Catalyst switches.

• WS-PWR-PANEL—power patch panel t hat allows the Cisc o IP Pho ne to be

connected to existing Catalyst 400 0, 5000, and 60 00 family 10/1 00BaseTX
switchi ng modules.

This module sends power on pins 4, 5, 7, & 8, which are not used for Ethernet
signaling. The power patch panel also attempts to verify that the attached
device is a Cisco IP Phone before providing power.

Power Source Design

The phone and switch automatically determine which power source the phone
uses. If the power has to be switched to a different source, the phone user will
experience different results based on which power source is being used by the
phone.

Use the following in for mat ion t o choo se a power sou rce for t h e phone :

• If you plug a phone into the optional pow er supply before plugging it in to the

network, the phone is powered by the power supply.

• If you then unplug the phon e fr om the power suppl y, the phone resets. If th e

switch port is configured for 10/ 100 Mbp s, t he swi tch re co gniz es the lo ss of
power and brings t he phon e ba ck u p.

• If the switch port is configure d f or 10 M bps on ly, then you must u nplug the

network connection an d p lug i t ba ck i nto t he p hone for t he s wit ch t o
recognize the p hone’s loss of power.

• If, however, you plugged the network co nne ctio n in to the p hon e be for e yo u

plugged in the power cord, the phone receives power through the switch, and

Redundancy Feature

For redundancy, you can use the Cisco AC adapter even if you are using inline
power fr om the Cisco Cataly st s wi t ches . T he C is c o IP Phone can shar e the power
load being used from the inline power and external power source. If either the
inline power or the exte rnal powe r goes do wn, the phone c an switch entirely to the
other power source.

To use this re dund ancy fe a ture :

1. Set the inline power mode to auto on the Cisco Catalyst switch.

2. Connect the unpowered Cisco IP Phon e to the ne twork.

3. Connect the external power supply to the phone afte r the phone powers up.

Adding Phones to the Cisco Call Manager Database

Adding Phones to the Cisco CallManager Database

Before installing any Cisco IP phones, you must ma ke decisions about how you
want the phones to be added to the Cisco CallManager database. Because
Cisco C allManager handles call processing in the network, this is a critical step.

You can add phones to the Cisco CallMana ger dat abase au tomat ically us ing
auto-registration, manually using the Cisco CallManager Administration
application, or in groups with the Bulk Administration Tool (BAT).

Once you add a Cisco IP phone using the Cisco Cal lManage r Administra tion
application, the Phone Configuration Window in the application displays the
device name, registration status, and the IP ad dress of the Cisco CallMa nager to
which the device is registered.

This section covers the following topics:
