OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.
The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required
to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not
installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to
comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable
protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.
Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital
devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television
communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its
peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:
• Turn the television or radio antenna until the interference stops.
• Move the equipment to one side or the other of the television or radio.
• Move the equipment farther away from the television or radio.
• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits
controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

An Overview of the Conference Station
The Cisco Unified IP Conference Station 7937G is a full-featured teleconference station that provides
voice communication over an Internet Protocol (IP) network. It functions much like a digital business
phone, allowing you to place and receive calls and to access features such as mute, hold, transfer,
dial, call forward, and more. In addition, because conference stations are connected to your data
speed
network, they offer enhanced IP telephony features, including access to network information and
services, and customizable features and services. The conference stations also support certain security
features.
The conference station provides a backlit LCD screen, support for up to ten speed dial numbers, and a
variety of other sophisticated functions.
The conference station, like other network devices, must be configured and managed. The conference
stations encode G.711a, G.711u, G.729a, G.729ab, and decode all variants of G.711 and G.729. The
conference stations also support 16-bit/16-kHz wideband audio.

Networking Protocol Purpose Usage Notes
Cisco Discovery
Protocol (CDP)
Dynamic Host
Configuration Protocol
(DHCP)
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.
DHCP dynamically allocates and
assigns an IP address to network
devices.
Tabl e 1-1 provides an overview of the networking protocols that the
The conference station 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 must manually
configure the IP address, subnet mask, gateway, and a TFTP
server on each conference station locally.
Chapter 1 An Overview of the Conference Station
DHCP enables you to connect a
conference station into the network
and have the conference station
become operational without you
needing to manually assign an IP
address or to configure additional
network parameters.
Hypertext Transfer
Protocol (HTTP)

addresses and sends packets across
the network.
RTP is a standard protocol for
transporting real-time data, such as
interactive voice and video, over data
networks.
SCCP includes a messaging set that
allows communications between call
control servers and endpoint clients
like IP conference stations. SCCP is
proprietary to Cisco Systems.
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 DCHP
configurations, refer to the “Cisco TFTP” chapter in
Unified Communications Manager System Guide.
Cisco
The conference stations uses HTTP for the XML services
and for troubleshooting purposes.
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 conference
station with DHCP. If you are not using DHCP, you must
manually assign these properties to each conference station
locally.
The conference station uses the RTP protocol to
receive real-time voice traffic from other conference
send/
stations and gateways.
The conference station uses SCCP for call control.

• Network Configuration Menu, page 4-5
The conference station uses TCP to connect to
Unified Communications Manager and to access
Cisco
XML services.
TFTP requires a TFTP server in your network, which can be
automatically identified from the DHCP server. If you want
a conference station to use a TFTP server other than the one
specified by the DHCP server, you must manually assign a
TFTP server from the Network Configuration menu on the
conference station.
The conference station transmits and receives RTP streams,
which utilize UDP.
What Features are Supported on the Conference Station?
The conference station functions much like a digital business conference station, allowing you to place
and receive teleconference station calls. In addition to traditional telephony features, the conference
station includes features that enable you to administer and monitor the conference station as a network
device.
This section includes the following topics:
• Feature Overview, page 1-5
• Configuring Telephony Features, page 1-6
• Configuring Network Parameters Using the Conference Station, page 1-6
• Providing Users with Feature Information, page 1-7
Feature Overview
Conference stations provide traditional telephony functionality, such as call forwarding and transferring,
redialing, speed dialing, conference calling, and voice messaging system access. Conference stations
also provide a variety of other features. For an overview of the telephony features that the conference
station supports, see the
As with other network devices, you must configure conference stations to prepare them to access
Unified Communications Manager and the rest of the IP network. By using DHCP, you have fewer
Cisco
settings to configure on a conference station, 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 conference station, see
“Telephony Features Available for the Conference Station” section on page 5-1.

What Features are Supported on the Conference Station?
The conference station can interact with other services and devices on your IP network to provide
enhanced functionality. For example, you can 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 5-6 and the
“Setting Up Services” section on page 5-8.
Finally, because the conference station 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 conference stations. See
Statistics on the Conference Station,” for more information.

The conference station can be powered with external power or with Power over Ethernet (PoE). External
power is provided through a separate power supply. PoE is provided by a switch through the Ethernet
cable attached to a conference station.
Note When you install a conference station that is powered by an optional external power supply, do the
following:
• Use a power interface cable to attach to the PoE cable and LAN wall port. See the “Installing the
Conference Station” section on page 3-4 for instructions on how to attach the power interface cable.
• Connect the power supply to the conference station and to a power outlet before you connect the
