Configuring Dialing Options

LifeSize Room provides simultaneous video, VoIP, or PSTN connectivity.
You can choose voice and video dialing options during the initial configuration or at any

other time by accessing the Administrator Preferences : Communications. Select the
protocol to use when dialing voice or video calls.

For voice calls, VoIP uses H.323 or SIP, Touch Tone and Pulse use PSTN.
For video calls, choose IP or IP + ISDN or ISDN for ISDN connectivity.
When placing a call off hook (using the Voice button on the phone) and voice dialing is set

to touch tone or pulse, you can only dial phone numbers using PSTN connectivity. When
voice dialing is set to VoIP, you can dial IP addresses as well as phone numbers.

When dialing on hook (using the remote control or using the Video button on the phone),
you can dial either phone numbers or IP addresses. This enables systems inside a
corporate network without access to a gateway to call other LifeSize Phones in the network
using system IP addresses.

Configuring Network Usage

General network configuration is available from the administrator preferences.

Configuring LAN Properties

To configure network settings, select the Administrator Preferences and Network buttons.
From this menu you can establish DHCP or Static IP network settings.

Note: If you change IP settings the system automatically restarts.

Dynamic Host Configuration Protocol (DHCP) is used to dynamically allocate and assign IP
addresses. DHCP allows you to move network devices from one subnet to another without
administrative attention. You can choose to enable DHCP if a DHCP server is present. If you
disable DHCP, you must identify an IP address (the locally configured IP address if not
assigned by a DHCP server), subnet mask (used to partition the IP address into a network
and host identifier), and gateway (IP address of the default gateway the system uses).

You can also define the broadcast IP address o f your network, hostna me of the system, and
identify the IP addresses to configure DNS servers.

As well, you can define the domain names to search when resolving hostnames. Domain
Name System (DNS) is used for translating names of network nodes into addresses; specify
this preference to use DNS to resolve the hostnames of devices to IP addresses.

LifeSize Room User Guide 25

Specifying H.323 Settings

To make a call using a name or extension with the H.323 protocol you must set the H.323
preferences (select Administrator Preferences : H.323). Enter the name and extension of
the device used when making calls with H.323. These are optional values that identify the
device to the gatekeeper. Any registered device can dial another using this ID and phone
number.

If the system is registered to a gatekeeper, the system displays its status. If you wish
LifeSize Room to automatically discover an H.32 3 ga te keep er set th e Gatekeeper Mode
preferences to Auto. You can also set the gatekeeper to Manual to manually choose a
gatekeeper. If set to Manual, specify the IP address and port for the primary gatekeeper.
Configuration of a secondary H.323 gatekeeper is optional.

Set the Gatekeeper ID only if the gatekeeper requires it (for example, configurations with
multiple gatekeepers). The Gatekeeper ID must match the Gatekee per ID configured on the
gatekeeper to which the system is registering. Do not configure this preference if the
gatekeeper does not require it as this may result in failure to register with the gatekeeper.

You can also enable H.245 tunneling to avoid creating an extra TCP connection for H.245
negotiation. To set H.245 preferences, access Administrator Preferences :
Communications : H.245 Tunneling.

Note: If you wish to display presentations (as described in "Presentations" on
page 18), disable H.245 Tunneling. This preference is disabled by default.

Configuring SIP Settings

Session Initiation Protocol (SIP) is the Internet Engineering Task Force's (IETF's) standard
for multimedia conferencing over IP. SIP is an ASCII-based, application-layer control
protocol that establishes, maintains, and terminates calls be tween two or more devices.

To configure SIP as the protocol to use for placing calls, select the SIP button in the
Administrator Preferences. You can then configure the SIP server or advanced SIP
preferences.

H.323 Name Also referred to as H.323 ID. This optional value is used when a

Gatekeeper is configured and requires the system to register with an
H.323 ID. If the Gatekeeper Administrator assigns an H.323 ID for the
system, this field should contain that ID.

H.323 Extension This optional value is used when a Gatekeeper is configured and requires

the system to register with an E164 number or extension. If the
Gatekeeper Administrator assigns an E164 number or extension for the
system, this field should contain that number.

26 LifeSize Room User Guide

For the server, enter the username, SIP server authorization name, and password for the
device, if required. The authorization name and password are the values LifeSize Room
uses for authentication; these values are only required if the registrar or proxy require
authentication.

You can also configure proxy settings to enable and configure the SIP proxy and SIP
registrar. SIP devices use register settings to dynamically register their current location.

Advanced SIP preferences enable you to change the SIP UDP or TCP signaling ports and
the communication path to use for SIP registration.

Configuring NAT/Firewall Settings

You can configure your system to use a static Network Address Translation (NAT) server to
traverse your firewall by setting Administrator Preferences : NAT/Firewall. You can set
the public IP address and identify UDP and TCP port numbers to allow communications with
devices outside of your private network. This configuration also requires changes on your
router to forward the selected ports to the private IP address of the LifeSize device.

Configuring Call Preferences

Users can set preferences for calls such as network bandwidth and auto answer options.
Refer to "User Preferences" on page 21 for details about these preferences. For more
information about Auto Answer options, refer to "Automatically Answering Calls" on
page 12.

Administrators can also configure the maximum call time in Administrator Preferences :

Call.
Managing Bandwidth

By default, calls automatically dete ct the av ailable ba ndwidth in the connection and connect
at that rate. If a device with lower bandwidth joins a call, the call slows to the highest
common bandwidth of all devices in the call. If a device with the lowest bandwidth in a call
disconnects from the call, the call increases its speed to the originating common bandwidth.

Administrators can specify the maximum call speed for a call by setting the Administrator
Preferences : Calls : Incoming/Outgoing Maximum Bandwidth preferences. This setting
overrides any bandwidth a user may specify when placing an outgoing call.

Customizing Your System

The system supports 12 different languages. Users can select a preferred language during
the initial configuration of the system or change it at an y tim e by ch ang ing the valu e in User

LifeSize Room User Guide 29

Configuring VGA Output

Automatic configuration of VGA displays may not detect all displays. The following
conditions may occur with some VGA monitors:

• Failure to read the Extended Display Identification Data (EDID) of the display.
LifeSize Room detects the display as VGA, but cannot determine its supported

resolutions. LifeSize Room configures the display output to VGA at 1280x768. EDID is
a VESA standard data format that contains general information about a display and its
capabilities, including vendor information, maximum image size, color characteristics,
factory pre-set timings, frequency range limits, and character strings for the display
name and serial number.

• Failure to detect the display as a VGA device.
LifeSize Room configures the output to 720p. Most VGA monitors display this signal,

however, the data is not centered and may be tinted green. You must manually
configure the appropriate display as VGA to resolve this issue.

• The resolution of the display is unsupported.
LifeSize Room is a high definition video confe rencing system th at requ ire s displa ys that

support 1280x720 or 1280x768 resolutions. If a VGA display EDID does not cont ain one
of these resolutions, LifeSize Room automatically configures it for 1280x768. Most
multi-sync VGA displays can adjust to this resolution and scale the dat a to fit the screen,
which is typically 4x3. If scaling occurs, the resulting image may be slightly distorted. For
example, a display that only supports 1024x768 will scale the 1280x768 image causing
it to appear narrow. If a display cannot adjust to the 1280x768 resolution, its screen
remains blank or a message displays indicating the resolution is not supported. LifeSize
Room does not support displays that do not support 1280x768.

When LifeSize Room does not automatically address one of these conditions, you must
manually configure the display output. You can configure the display output from the
LifeSize Room onscreen interface or from the LCD interface on the LifeSize Phone
connected to your LifeSize Room system as described in the following sections.

Configuring Display Output from LifeSize Room

If your LifeSize Room system displays the initial configuration screen or the display is not
showing an image, you must configure the display from the LifeSize Phone. Refer to
"Configuring Display Output from LifeSize Phone" on page 30.

common problems you may encounter with your LifeSize Room.

When experiencing a problem, visually inspect the unit. Ensure the system has not been
exposed to water or heat sources or appears physically damaged.

Improperly connected or loose cables are common causes of problems with har dware unit s.
When investigating a system problem, first check all the external controls and cable
connections. Check that connections are correct and secure, and that nothing is obstructing
the cables.

LifeSize Room User Guide 34

Camera Issues

The infrared (IR) sensor for the remote control is located in front of the camera . The reach of
the remote control signal is 10 meters. If your system is not responding, first ensure the
camera is positioned correctly and that usage of the remote is within 10 meters of the
camera.

If you are unable to pan, tilt, or zoom the camera, ensure the remote control contains three
AAA batteries that are in good working condition. Also verify that no objects are obstructing
the sensor on the front of the camera.

If no video displays from the camera, en sure the ca mer a is conn ecte d to LifeSize ro om wi th
a camera cable to the camera 1 input as described in "Installing LifeSize Room" on page 3.
Also ensure that the primary input is set to the high definition camera as described in
"Selecting Input" on page 16. You may need to adjust camera brightness or white balance;
set the Diagnostics: High Definition Camera preference until the picture is clearer.

Ve rify that the light on the front of the camera is lit, indicating that power is active, and reboot
the system if necessary to verify that the camera turns on.

The camera included with your LifeSize Room system includes designated calibration files
for that particular system. Therefore, if you have more than one LifeSize Room system and
wish to exchange or move a camera from one system to a nothe r, once you connect it to the
system it initializes and downloads the necessary camera files for the new codec. This
process takes approximately three to four minutes the first time you connect the new camera
to the new codec. Do not unplug the camera during this process.

Adjusting Room Lighting

You can assist the system to maintain the best possible image quality by altering the
environmental lighting and background colors of your environment. The optimal lighting for
standard conference rooms using LifeSize Room is 3 00 to 500 LUX. Consult your LifeSize
Channel Partner for details ab out the specific lighting requirements for your environment.

Avoid direct sunlight on the subject matter, the background, or the camera lens as this
creates harsh contrasts.

If light levels are too low you may consider adding artificial lighting. However you should
avoid direct illumination of the subject matter and camera lens. Avoid colored lighting.
Indirect light from shaded sources or reflected light from p ale walls of ten produces excellent
results. Avoid harsh side lighting or strong light from above.

Dim scenes can also be improved by manually adjusting the camera brightness setting. To
manually adjust the camera brightness, set the Diagnostics: High Definition Camera:
Camera Brightness preference.

35 LifeSize Room User Guide

Display Issues

The following issues are related to the user interface or the display on the LifeSize Phone.

Display Failures

If data does not appear on the display, ensure the unit is properly plugged in. Ensure cables
are properly connected into inputs on the display and that the display cable is connected to
the Display 1 output on the back panel of the codec.

Also ensure you have selected the correct input. Refer to "Selecting Input" on page 16 for
more information.

If using a second display and nothing appears or yo u see dat a from only one in put, you may
be using an unsupported display or the secondary input is turned off. Navigate to User
Preferences : Appearance : Secondary Display Layout and ensure it is not set to None.
If this preference is disabled and you are unable to modify it, you are using an unsupported
display.

If you connect to an unsupported display an error message displays and the user interface
may not appear correctly or you may see distorted images. Refer to the Release Notes for a
list of supported displays. Some displays, though unsupported, may appear to work;
however, you will experience significant quality and performance issues and the system will
not operate properly. To achieve optimal resolution LifeSize recommends using the HD-15
to Component RCA cables included with your system.

If the video and LifeSize Room display appear washed out or too bright, check the input
settings of your HDTV to make sure the HDTV is displaying the appropriate resolution.
Some HDTVs (particularly plasma displays) allow you to configure the native resolution of
the input device from the HDTV administration interface.

If you are connecting a display using an HD-15 to Component RCA cable and the screen
displays a series of black lines, adjust the NTSC/P AL switch to rectify the problem.

Refer to "Configuring VGA Input" on page 28 and "Configuring VGA Output" on page 29 for
more information about configuring VGA.

LifeSize Room User Guide 36

IP Address Displays Invalid Value

If the IP address displays an invalid value, one of the following conditions may be occurring:

Poor Quality Display
If you have poor quality or unreadable data on the LifeSize Phone display, adjust the User

Preferences : LCD Contrast setting. The default setting (6) is recommended.

If the colors on the display appear incorrect verify that the RGB cable is properly connected
to the display.

If you experience poor motion handling or visible tiling in the far end picture during a video
call, check the following:

• You have adequate bandwidth for the data rate at which you are trying to establish the
call.

• The Internet or private line connection you are using is optimized for video calls.

• The switch/router configuratio n in you r network is configured for full duplex 100-base T.

Missing Input

If you have not connected all possible video inputs, the input selection dialog displays a blue
image by default. If you select an input that is not connected, a full screen view of random
data displays. Connect the necessary input or choose a different input as described in
"Selecting Input" on page 16.

Unable to Display Presentations

If you are unable to display presentations as described in "Presentations" on page 18,
ensure you have disabled the H.245 tunneling preference. Access Administrator

Preferences : Communications : H.245 Tunneling. This preference is disabled by default.

address, but no IP address has been
entered in the address field.

Identify and enter the necessary IP information if you disable
DHCP.

Network connection is unavailable. Check your network connection.

37 LifeSize Room User Guide

Audio Issues

The following issues are related to the audio quality.

Absent Dial Tone

If you do not receive a dial tone after pressing the or key to initiate a call, ensure
the speaker volume is adjusted appropriately.

Also ensure the line out is securely connected.
An absent dial tone may also result from an unavailabl e analog phone line connecti on. If you

are connecting with PSTN, ensure the analog phone connection is secure and that it is
connected to an active phone line jack.

Problematic Sound Quality

If you are unable to hear the phone ring when an incoming call arrives, the speaker volume
may be set too low. (The LEDs flash blue to indicate an incoming call.) Adjust the volume
using the up and down volume key. If you still experience audio problems, adjust the Ring
Tone Volume preference (from the User or Administrator Preferences : Audio menu).

Muffled audio reception fro m the far side may b e caused by highly reverb erant rooms. If you
are experiencing poor audio reception, add more sound absorbency to the room and speak
in close proximity to the phone.

Adjust the priority order for your audio codec if you have chosen a low-bandwidth audio
codec to be first. Ensure that the far end caller has configured the phone correctly and is in
an acoustically benign environment. For best results, ensure the far end caller is using a
LifeSize Phone. Audio quality from your LifeSize Room system will vary when calling a non­LifeSize audio or video unit. LifeSize Room will use the audio codec that the non-LifeSize
system supports.

Degradation in the audio quality can also be caused by faulty microphones or dust and
debris accessing the phone. Do not use any kind of liquid or aerosol clea ner on the phone. A
soft, slightly damp cloth should be sufficient to clean the top surface of the phone if
necessary.

If you experience a high frequency buzzing sound when you plug your LifeSize Room
system into external powered speakers, you may be experiencing common mode noise. To
eliminate this condition, insert an Isolation Transformer (also called a Ground Loop
Eliminator) from your local electronics store between the LifeSize Room output and the
loudspeaker input.

LifeSize Room User Guide 38

Distorted Audio

Poor audio quality may result from a bad network connection. Ensure that your network
connection is capable of handling the correct bandwidth; LifeSize recommends that your
network connection be capable of at least 100Mbps (100-baseT) for best performance.

Also ensure the loudspeaker is not obscured or damaged at either end of the call. Do not
stack items on top of the phone. Ensure both ends are not muted. Verify that the Audio Out
cables are properly connected to th e disp la y and that any external speaker systems are
powered and configured correctly. If an external speaker system has its own volume control,
adjust the volume to near maximum (in the range from 7-10) on the LifeSize audio output
and adjust the volume control on the external speaker system for the best results.

Power and Connectivity Issues

Network status is indicated at all times in the bottom right corner of the screen by the
following icons:

When you place a call, the Call St atus dialog displays, indicating th e current state of the ca ll
(such as dialing, ringing, connected, answered, etc.). The state of a call is also indicated in
the Call Manager dialog.

If a call does not successfully connect, verify that you have dialed a working number and
that the far end destination is powered on and available. Verify that network settings are
appropriate.

When placing a call using an IP address, if you experience one way audio or video, contact
your network administrator to make sure that the IP address you are using has access to
open network ports 1024 to 66536 to ensure that video and audio traffic is available.

Performance Issues

If you are experiencing performance issues, unplug the display a nd plug it back in. If an error
message displays, indicating you are using an unsupported monitor, connect to a different
display with a supported resolution. Refer to the LifeSize Room Release Notes for a list of
supported displays with this release.
