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

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.

(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.

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.

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.

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.

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

NoteCisco recommends you use auto-registration and TAPS to add less than 100 conference stations to your
network. To add more than 100 conference stations to your network, use the Bulk Administration Tool
(BAT). See the “Adding Conference Stations with BAT” section on page 2-9.
To implement TAPS, you or the end-user dial a TAPS directory number and follow voice prompts. When
the process is complete, the conference station will have downloaded its directory number and other
settings, and the conference station will be updated in Cisco
Administration with the correct MAC address.
Auto-registration must be enabled in Cisco Unified Communications Manager Administration for TAPS
to function.

Understanding the Conference Station Components
The conference station includes these components:
•Network Ports
•Audio Auxiliary Port
Network Ports
The underside of the conference station includes these connector ports:
•Ethernet network port (RJ-45)—Labeled “LAN”
•Two external microphone ports (mini-VGA)—Labeled with stenciled microphone icons
Each type of port supports 10/100 Mbps half- or full-duplex connections to external devices. You can
use either Category 3 or 5 cabling for 10-Mbps connections, but you must use Category 5 for 100 Mbps
connections.
Use the Ethernet network port to connect the conference station to the network. You must use a
straight-through cable on this port. The conference station can also obtain inline power from a switch
over this connection (Power over Ethernet).
Figure 3-1 shows how to connect the conference station to
the network using Power over Ethernet (PoE). If you use an external power source, rather than PoE, to
connect the conference station to the network, see
Figure 3-2. For more information on powering the
conference station, see the “Providing Power to the Conference Station” section on page 2-2.

through the startup process, the cause may be faulty cables, bad connections, network outages, lack of
power, and so on. Or, the conference station may not be functional.
To determine whether the conference station is functional, follow these suggestions to systematically
eliminate these other potential problems:
1. Verify that the network port is functional:
–
Exchange the Ethernet cables with cables that you know are functional.
–
Disconnect a functioning conference station from another port and connect it to this network
port to verify the port is active.
–
Connect the conference station that will not start up to a different network port that is known to
be good.
–
Connect the conference station that will not start up directly to the port on the switch,
eliminating the patch panel connection in the office.
2. Verify that the conference station is receiving power:
“Verifying the Conference Station Startup Process” section
–
If you are using external power, verify that the electrical outlet is functional.
–
If you are using in-line power, use the external power supply instead.
–
If you are using the external power supply, switch with a unit that you know to be functional.
3. If the conference station still does not start up properly, perform a factory reset of the conference
station. For instructions, see the
If after attempting these solutions, the LCD screen on the conference station does not display any
characters after at least five minutes, contact a Cisco technical support representative for additional
assistance.

Checking Network Connectivity
If the network is down between the conference station and the TFTP server or
Unified Communications Manager, the conference station cannot start up properly. Ensure that the
Cisco
network is currently running.
Verifying TFTP Server Settings
You can determine the IP address of the TFTP server used by the conference station by choosing
Applications > Settings > Network Configuration, and then scrolling to the TFTP Server 1 option.
If you have assigned a static IP address to the conference station, you must manually enter a setting for
the TFTP Server 1 option. See the
If you are using Dynamic Host Configuration Protocol (DHCP), the conference station obtains the
address for the Trivial File Transfer Protocol (TFTP) server from the DHCP server. A valid TFTP server
must be set in DHCP option 150 or option 66 on the DHCP server.
You can also enable the conference station to use an alternate TFTP server. Such a setting is particularly
useful if the conference station was recently moved from one location to another. See the
Configuration Menu” section on page 4-5 for instructions.

“Network
Verifying IP Addressing and Routing
You should verify the Internet Protocol (IP) addressing and routing settings on the conference station. If
you are using DHCP, the DHCP server should provide these values. If you have assigned a static IP
address to the conference station, you must enter these values manually.
On the conference station, choose Applications > Settings > Network Configuration, and look at the
following options:
•DHCP Server—If you have assigned a static IP address to the conference station, you do not need
to enter a value for the DHCP Server option. However, if you are using a DHCP server, this option
must have a value. If it does not, check your IP routing and VLAN configuration. Refer to
Troubleshooting Switch Port Problems, available at this URL:
http://www.cisco.com/warp/customer/473/53.shtml
•IP Address, Subnet Mask, Default Router—If you have assigned a static IP address to the conference
station, you must manually enter settings for these options. See the
section on page 4-5 for instructions.
If you are using DHCP, check the IP addresses distributed by your DHCP server. Refer to Understanding and Troubleshooting DHCP in Catalyst Switch or Enterprise Networks, available at this URL:
If you are using DNS to refer to the TFTP server or to Cisco Unified Communications Manager, you
must ensure that you have specified a Domain Name System (DNS) server. Verify this setting by
choosing Applications > Settings > Network Configuration, and scrolling to the DNS Server 1 option.
You should also verify that there is a CNAME entry in the DNS server for the TFTP server and for
Unified Communications Manager.
Cisco
You must also ensure that DNS is configured to do reverse look-ups.

If none of these options contain IP addresses or show Active or Standby, the conference station is not
properly registered with Cisco
Unified Communications Manager. See the “Registering the Conference
Station with Cisco Unified Communications Manager” section on page 9-6 for tips on resolving this
problem.
Cisco Unified Communications Manager and TFTP Services Are Not Running
If the Cisco Unified Communications Manager or TFTP services are not running, conference stations
may not be able to start up properly. However, in such a situation, it is likely that you are experiencing
a system-wide failure and that other conference stations and devices are unable to start up properly.
If the Cisco Unified Communications Manager service is not running, all devices on the network that
rely on it to make conference station calls will be affected. If the TFTP service is not running, many
devices will not be able to start up successfully.

conference station has been added to the server or if auto-registration is enabled. Review the information
and procedures in the
“Adding Conference Stations to the Cisco Unified Communications Manager
Database” section on page 2-7 to ensure that the conference station has been added to
Cisco Unified Communications Manager.
To verify that the conference station is in the Cisco Unified Communications Manager database, choose
Device > Phone from Cisco Unified Communications Manager Administration and search for the
conference station based on its MAC Address. For information about determining a MAC address, see

Symptom: Conference Station Unable to Obtain IP Address
If a conference station is unable to obtain an IP address when it starts up, the conference station may not
be on the same network or VLAN as the DHCP server, or the switch port to which the conference station
is connected may be disabled.
Make sure that the network or VLAN to which the conference station is connected has access to the
DHCP server, and make sure that the switch port is enabled.

Conference Station Resets Unexpectedly
If users report that their conference stations are resetting during calls or while idle on their desk, you
should investigate the cause. If the network connection and Cisco
connection are stable, a conference station should not reset on its own.
Typically, a conference station resets if it has problems connecting to the Ethernet network or to
Unified Communications Manager. These sections can help you identify the cause of a conference
•Eliminating DNS or Other Connectivity Errors, page 9-8
•Checking Power Connection, page 9-9

Unified Communications Manager
Verifying Physical Connection
Verify that the Ethernet connection to which the conference station is connected is up. For example,
check if the particular port or switch to which the conference station is connected is down and that the
switch is not rebooting. Also make sure that there are no cable breaks.
Identifying Intermittent Network Outages
Intermittent network outages affect data and voice traffic differently. Your network might have been
experiencing intermittent outages without detection. If so, data traffic can resend lost packets and verify
that packets are received and transmitted. However, voice traffic cannot recapture lost packets. Rather
than retransmitting a lost network connection, the conference station resets and attempts to reconnect its
network connection.
If you are experiencing problems with the voice network, you should investigate whether an existing
problem is simply being exposed.
Verifying DHCP Settings
Follow this process to help determine if the conference station has been properly configured to use
DHCP:
1. Verify that you have properly configured the conference station to use DHCP. See the
“Network Configuration Menu” section on page 4-5 for more information.
2. Verify that the DHCP server has been set up properly.
3. Verify the DHCP lease duration. Cisco recommends that you set it to 8 days.
Conference stations send messages with request type 151 to renew their DHCP address leases. If the
DHCP server expects messages with request type 150, the lease will be denied, forcing the
conference station to restart and request a new IP address from the DHCP server.

Checking Static IP Address Settings
If the conference station has been assigned a static IP address, verify that you have entered the correct
settings. See the
“Network Configuration Menu” section on page 4-5 for more information.
Verifying Voice VLAN Configuration
If the conference station appears to reset during heavy network usage (for example, following extensive
web surfing on a computer connected to the same switch as conference station), it is likely that you do
not have a voice VLAN configured.
Isolating the conference stations on a separate auxiliary VLAN increases the quality of the voice traffic.
See the
page 2-1 for details.

Eliminating DNS or Other Connectivity Errors
Chapter 9 Troubleshooting and Maintenance
If the conference station continues to reset, follow these steps to eliminate DNS or other connectivity
errors:
Procedure
Step 1Use the Erase softkey to reset conference station settings to their default values. See the “Resetting or
Restoring the Conference Station” section on page 9-11 for details.
Step 2Modify DHCP and IP settings:
a. Disable DHCP.
b. Assign static IP values to the conference station. Use the same default router setting used for other
functioning conference stations.
c. Assign TFTP server. Use the same TFTP server used for other functioning conference stations.
See the “Network Configuration Menu” section on page 4-5 for instructions on modifying the above
three settings.
Step 3On the Cisco Unified Communications Manager server, verify that the local host files have the correct
Unified Communications Manager server name mapped to the correct IP address.
Cisco
Step 4From Cisco Unified Communications Manager Administration, choose System > Server to locate the
server, and then click the server name. Verify that the server is referred to by its IP address and not by
its DNS name.
Step 5From Cisco Unified Communications Manager Administration, choose Device > Phone to locate the
conference station, and then click the conference station name. Verify that you have assigned the correct
MAC address to this conference station. For information about determining a MAC address, see the

through the network connection; if power comes
through the connection, the network card can be
destroyed. To protect a network card, wait 10
seconds or longer after unplugging the cable from
the conference station before plugging it into a
computer. This delay gives the switch enough time to
recognize that there is no longer a conference station
on the line and to stop providing power to the cable.
