Configuring Network Usage  
To configure preferences that affect how your system functions with other servers and devices on your local network, access  
Administrator Preferences : Network : General.  
3
NOTE  
This unit cannot detect a change to its IP address if the change is due to a change in networks from a wiring closet or through  
software, such as a change to a router configuration. Reboot the system if the DNS changes.  
Specifying a Locally Configured IP Address  
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 enter 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).  
Specifying the Hostname and Domain Name Service (DNS) Servers  
You can enter the hostname of the system and the IP addresses to configure DNS servers. You can also enter the domain  
names to search when resolving hostnames. Domain Name System (DNS) translates names of network nodes into addresses;  
specify this preference to use DNS to resolve the hostnames of devices to IP addresses.  
Specifying Network Speed  
If you choose an option other than Auto for the Administrator Preferences : Network : General : Network Speed  
preference, ensure that it matches the speed and duplex configured on your network switch.  
NOTE  
If your Ethernet switch is configured for half duplex, you may experience poor quality video when placing calls greater  
than 512 Kb/s.  
To work around this issue, change your Ethernet switch configuration to a setting other than half duplex when using Auto  
for the Network Speed preference.  
36  
Installation  
Specifying a VLAN Tag  
If you have static virtual local area networks (VLANs) configured in your environment, you can configure your system to apply  
a VLAN tag to outgoing packets and only accept incoming tagged packets that have the same VLAN identifier.  
To enable this feature, navigate to Administrator Preferences : Network : General : VLAN Tag and specify the VLAN  
identifier of the VLAN to which the system is assigned. The value is a number in the range 1 through 4094.  
NOTE  
If you set or modify the VLAN Tag preference, the system reboots when you navigate to another screen.  
Specifying an NTP Server  
The system date and time that appear in the user interface are automatically set if one of the following conditions exists:  
3
•
The Administrator Preferences : Network : General : DHCP preference is set to Enabled, and the DHCP server can pass  
an NTP server address to your system.  
- or -  
•
The hostname or IP address of an NTP server is specified in Administrator Preferences : Network : General : NTP  
Server Hostname.  
NOTE  
An NTP server address that a DHCP server passes to your system overrides an NTP server hostname or address specified  
in the NTP Server Hostname preference.  
The System Information page displays the IP address of the NTP server that the system uses.  
NOTE  
The time zone is not set automatically. If you did not specify the time zone for your system during the initial configuration,  
the time that appears in the user interface may not be correct. To specify the time zone manually, refer to“Manually Setting  
System Date and Time”on page 47.  
Enabling IPv6 Addressing  
This system supports dual configuration of IPv4 and IPv6 addressing for the system IP address only. You cannot disable IPv4  
addressing on your system. Calls placed with an IPv6 address use the H.323 protocol.  
In addition to specifying a local IPv4 IP address (through either DHCP or by manually specifying a static IP address), you can  
assign an IPv6 address to your system if you are using IPv6 addressing on your network. Access Administrator Preferences :  
Network : General and choose Enabled for the IPv6 preference.  
If your IPv6 network sends router advertisements, select Auto for the IPv6 Configuration preference to automatically assign  
the IPv6 address to the system. The default option is Auto. If you select Manual for this preference, you can specify a static  
IPv6 address for the system in the IPv6 Address preference and the address of your IPv6 router in the IPv6 Router preference.  
NOTE  
Enabling or disabling IPv6 causes the system to reboot after you exit the preference screen.  
The IP address that appears at the top of the main screen in the user interface is the IPv4 address. The IPv6 address of the  
system appears in the System Menu on the System Information page.  
All other configuration preferences that require an IP address (for example, the NTP and DNS servers, H.323 gatekeeper,  
and SIP server) must be IPv4 addresses. You must also use the IPv4 address for your system to access the system remotely  
through the web administration interface and an ssh session.  
The directory supports IPv6 addresses. Users can also manually dial IPv6 addresses using the Video Call or Voice Call buttons  
on the main screen of the user interface and the 0x1a text entry method or screen keyboard. Refer to“Manually Dialing a  
Number from the Main Screen”on page 57 for information about changing the text entry mode.  
Installation  
37  
Enabling Network Address Translation (NAT)  
Network Address Translation (NAT) enables communication between devices on your LAN that have private IP addresses and  
devices that are accessed through a public IP network. Static NAT ensures that the same public IP address always maps to a  
system’s private IP address so that data from the public network intended for the private system can be routed to the system  
reliably.  
If you are using static NAT to associate a public IP address with the private IP address of your system, you must configure your  
system to work with your static NAT server. Access Administrator Preferences : Network : NAT and select Enabled for the  
Static NAT preference.  
Enter the public IP address, hostname, or fully qualified domain name of your system in NAT Public IP Address. The default  
entry method for this preference is numeric. To enter text, use the  
method to text.  
key on the remote control to change the entry  
3
NOTE  
If you are using a static firewall or NAT with fixed ports, you cannot register to a public gatekeeper. If you configure H.323  
settings and enable H.460 support, the system ignores preferences in Administrator Preferences : Network : NAT.  
Refer to“Enabling H.460 Support for H.323 Calls”on page 43 for more information.  
The following functions are not supported if your system is accessed from a web browser outside a firewall and static NAT is  
enabled:  
•

System Upgrade  
Directory Import  
To work around this issue, execute these functions from within the firewall.  
Restricting Reserved Ports  
By default, your system communicates through TCP and UDP ports in the range 2 048 to 65 534 for video, voice,  
presentations, and camera control. The system uses only a small number of these ports during a call. The exact number  
depends on the number of participants in the call, the protocol used, and the number of ports required for the type (video  
or voice) of call.  
To minimize the number of UDP and TCP ports that are available for communication, you can restrict the range by entering  
values in Administrator Preferences : Network : Reserved Ports. LG recommends that the range you choose, if other than  
a subset of the default range, begins with a port number greater than 10 000.  
NOTE  
Changing the TCP range causes an automatic reboot of the system.  
An H.323 video call with a presentation requires more ports than other types of calls.  
The following tables identify the number of ports required per connection by protocol and the type (video or voice) of call.  
Use this information if you need to further restrict the port range.

You can specify network Quality of Service (QoS) settings in the Administrator Preferences : Network : Network QoS  
preferences.  
Set these preferences according to the settings used in your network.  
NOTE  
Network QoS preferences are supported with IPv4 addressing only. If you enable IPv6 addressing on your LifeSize system,  
QoS preferences are ignored for IPv6 calls. For more information about IPv6 addressing, refer to“Enabling IPv6 Addressing”  
on page 36.  
You can specify DiffServ (differentiated services) or IntServ (integrated services) values for audio, video, and data packets.  
You can also set the IntServ Type of Service (ToS) preference.

Disabling Access to the Local Directory  
By default, users can place calls using entries in the local directory and add, remove, or modify these entries.  
For more information, refer to“Placing a Call from the Directory”on page 57.  
Administrators can disable user access to the local directory by setting Local Directory to Disabled in Administrator  
Preferences : Directory : General.  
3
Disabling access to the local directory also disables the following:  
•
•
saving entries from the REDIAL list to the local directory  
copying corporate directory entries to the local directory  
Administrators maintain access to the local directory on the web administration interface Directory page when the Local  
Directory preference is set to Disabled. For more information about managing the local directory from the web administration  
interface, refer to“Using Advanced Directory Features”on page 52.  
Populating the Corporate Directory  
Users can place calls from the directory by selecting a number to dial from a list of stored numbers.  
The corporate directory is H.350 compliant and can store up to 1000 entries in both an alphabetical and hierarchical format.  
All users can manage entries in the local directory. Only administrators can manage entries in the corporate directory.  
You can populate the corporate directory by configuring Auto Discovery preferences or Lightweight Directory Access  
Protocol (LDAP) preferences in Administrator Preferences :Directory. By default, auto discovery is enabled and LDAP  
is disabled. You can enable only one of these methods. The system automatically disables the other method to prevent  
duplicate entries from appearing in the corporate directory. The status of these methods, either enabled or disabled, appears  
on the Administrator Preferences : Directory screen. The connection status of the LDAP installation also appears on this  
page and on the System Information page.  
The values that can appear for the connection status include the following:

Configuring Auto Discovery  
Auto discovery enables the systems on your network to pass address information to other systems automatically.  
By default, when a system joins a network, it sends a broadcast packet to the local subnet to announce its presence.  
Any system on the local subnet that receives the packet and has Auto Discovery set to Enabled replies by sending address  
information about itself and a list of IP addresses of other systems that it has discovered.  
The system creates an entry in its corporate directory for every system on the local subnet from which it received a response.  
It then queries the list of other IP addresses that it received and the IP addresses that are stored in its own Redial list, but  
only if those addresses are allowed by the filters that you specify in the Auto Discovery Subnets and Auto Discovery Ignored  
Subnets preferences.  
By default, the system replies and sends queries to other systems in the local subnet only.  
Configure the Auto Discovery Subnets and Auto Discovery Ignored Subnets preferences to enable the system to discover  
other systems outside the local subnet and share that information with other systems.  
Specify subnet filters (separated by spaces) in the Auto Discovery Subnets preference to identify the subnets to which the  
LifeSize system can send queries and replies.  
By default, the preference is empty; the system sends queries and replies to other systems on the local subnet only.  
To exclude subnets from auto discovery, specify subnet filters in the Auto Discovery Ignored Subnets preference. If a  
destination address does not match one of the filters in the Auto Discovery Subnets preference, or if it matches one of the  
filters in the Auto Discovery Ignored Subnets preference, then the system does not query or reply to the system at that  
address.  
For example, you can configure the Auto Discovery Subnets preference to include a large subnet and the Auto Discovery  
Ignored Subnets preference to exclude a subset of the subnet. Consider a network that has several subnets with the IP  
address 10.* and a slow network connection to devices that have a 10.85.* address. If you enter 10.* in the Auto Discovery  
Subnets and 10.85.* in the Auto Discovery Ignored Subnets preference, the system queries and replies to all the systems that  
have a 10.* address, except those that have a 10.85.* address.  
If you set Auto Discovery to Disabled, the system does not send a broadcast message to the local subnet and cannot  
discover or be discovered by other systems.

Enabling Telepresence  
You can set the system to telepresence mode in which a conference administrator controls calls from a control panel (such as  
LifeSize Control or the Call Manager in the web administration interface).  
Enabling telepresence removes the user interface from view. When the system is idle, only the background image appears in the  
display. An administrator can access the user interface by pressing OK and entering the administrator password.  
During a call, users see the video from the call and the mute indicators. The navigation bar, PIP windows, caller ID information,  
and call status messages do not appear on the screen.  
Users can invoke the Call Manager dialog and call statistics and choose video inputs with the remote control. The numeric keys  
on the remote control play touch tones. Users can change this behavior from the Call Manager.  
To enable or disable telepresence and lock or unlock cameras, configure preferences in Administrator Preferences :  
Telepresence.

support.  
Specifying H.323 Settings  
By default, this system supports the H.323 protocol for placing and receiving video and voice calls.  
You can disable support for H.323 calls by selecting Disabled for the H.323 preference in Administrator Preferences :  
Communications : H.323 when the system is not in a call.  
If you choose Disabled for the H.323 preference, the system cannot place or receive calls with the H.323 protocol.  
NOTE  
If both H.323 and SIP preferences are set to Disabled, a warning message appears and indicates that video calls cannot be  
placed or received with this configuration.  
When H.323 is enabled, you can specify an H.323 name or extension to use when placing a call. The H.323 name and  
extension identify the device to the gatekeeper. Any registered device can dial another one using this name and extension.  
The H.323 Name preference is an optional value that 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, enter that ID for the H.323  
Name preference. The H.323 Extension preference is an optional value that 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, enter that number for the H.323 Extension preference.  
Set the Gatekeeper ID only if the gatekeeper requires it (for example, configurations with multiple gatekeepers). The  
Gatekeeper ID must match the gatekeeper ID configured for 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.  
Set the Gatekeeper Mode preference to Auto if you wish to have the system automatically discover a gatekeeper. You can  
also set the Gatekeeper Mode preference to Manual to manually choose a gatekeeper. If set to Manual, specify the IP address  
and port for the primary gatekeeper.  
When you select the Register button in Administrator Preferences : Communications : H.323, icons appear in the status  
bar to indicate the status of the registration process with the H.323 gatekeeper. The yellow H.323 icon  
appears when  
your system is trying to register with the gatekeeper. If the registration fails, the red H.323 icon  
is registered to a gatekeeper, the system displays its status.  
appears. If the system  
Configuring a secondary H.323 gatekeeper with the Gatekeeper IP Address 2 and Gatekeeper Port 2 preferences is optional.  
Installation  
43  
Enabling H.460 Support for H.323 Calls  
This system supports the H.460 protocol for firewall and NAT traversal of H.323 calls. You must have an H.460 server  
configured in your environment for this feature to function properly.  
NOTE  
If you configure H.323 settings and enable H.460 support, the system ignores preferences in Administrator Preferences :  
Network : NAT.  
To enable H.460 client support on a system, configure the H.323 preferences in Administrator Preferences :  
Communications : H.323 with the following exceptions:  
•
•
Choose Manual for the Gatekeeper Mode preference.  
For the Gatekeeper IP Address 1 and Gatekeeper Port 1 preferences, enter the IP address and port number of the H.460  
server that is configured in your environment.  
3
•
•
Choose Enabled for the H.460 preference.  
Navigate to Register and click OK.  
NOTE  
If you enable H.460 and specify the IP address and port number of a secondary gatekeeper with the Gatekeeper IP  
Address 2 and Gatekeeper Port 2 preferences, the system ignores the secondary gatekeeper.  
Configuring SIP Settings  
By default, support for Session Initiation Protocol (SIP) is enabled on the system. To configure SIP as the protocol to use for  
placing calls, configure SIP preferences in Administrator Preferences : Communications : SIP. You can also disable support  
for SIP by choosing Disabled for the SIP preference when the system is not in a call.  
If you choose Disabled for the SIP preference, the system cannot place or receive calls with the SIP protocol.  
NOTE  
If both H.323 and SIP preferences are set to Disabled, a warning message appears and indicates that video calls cannot be  
placed or received with this configuration.  
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 the system uses for authentication; these values are only required if the registrar or proxy  
require authentication.  
If you are planning on placing and receiving calls on this system with Microsoft Office Communications Server,  
LG recommends that administrators choose Microsoft OCS for SIP Server Type in Administrator Preferences :  
Communications : SIP. The default is Auto. For more information about using Microsoft OCS with LifeSize communications  
devices, refer to the technical note on the Support page of www.lifesize.com.  
You can change the communication path to use when registering with a SIP Registrar, either directly or through a proxy and  
configure proxy settings. SIP devices use register settings to dynamically register their current location.  
When you select the Register button and press OK, icons appear in the status bar to indicate the status of the registration  
process with the SIP server. The yellow SIP icon  
appears when your system is trying to register with the SIP server.  
If the registration fails, the red SIP icon  
appears.  
You can change the SIP UDP signaling port. You can also enable TCP signaling and change the TCP signaling port. You can  
enable Transport Layer Security (TLS) signaling and change the TLS signaling port only if the SIP Registrar preference is set  
to Enabled. TCP signaling and TLS signaling are mutually exclusive. Enabling one automatically disables the other. Choosing  
Disabled for the SIP Registrar preference automatically disables TLS signaling. If neither TCP nor TLS signaling is enabled, only  
UDP signaling is enabled.  
44  
Installation  
NOTE  
The system reboots if you change the UDP signaling port, enable or disable TCP or TLS signaling, or change the TCP or TLS  
signaling ports.  
If you enable TLS signaling, the system attempts to use Secure Real-time Transport Protocol (SRTP) for media encryption in  
SIP calls.  
If the far side supports SRTP, the media is encrypted and encryption icons appear in the caller ID, Call Manager list, and Call  
Statistics list in the user interface during a call. Refer to“Caller ID”on page 59 for a description of the icons.  
If the far end does not support SRTP, the media is not encrypted and call encryption icons do not appear in the user  
interface.

resolutions when you install your system or change a display and to troubleshoot display issues.  
You can set the Display Energy Saver preference to Enabled for connected displays to turn off the signal that the system  
sends to the display when the system goes to sleep.  
LG recommends that you test this feature for compatibility with your display before using it in your environment. Some  
displays may appear black when the signal from the system is no longer received, but not enter an energy saving state. Other  
displays may recognize the loss of the signal and show text indicating this state. This may result in the text image burning  
into the screen. Some displays may recognize the loss of the signal and power off, but then not wake up when the system  
wakes up.  
3
Configuring Video Behaviors  
Administrators can adjust video behaviors to control cameras and video quality by configuring preferences in Administrator  
Preferences : Video.  
Controlling the Camera Use by Far End Users  
To prevent far end users from controlling your PTZ near end camera, including configuring and controlling camera presets,  
choose Disabled for the Administrator Preferences : Video : Video Control : Far Control of Near Camera preference. If  
you choose Enabled, you can still prevent far end users from configuring and using near end camera presets by choosing  
Disabled for the Far Set of Camera Presets and Far Move to Camera Presets preferences.

Installation  
Selecting Priority of Quality Metrics for Source Video  
You can favor sharpness or motion as a priority for the quality of primary video that the system sends to the far end during a  
call.  
If you favor sharpness by selecting a smaller number for the Administrator Preferences : Video : Video Quality : Primary  
Video Motion preference, in lower bandwidth calls the system sends the primary video at a lower frame rate and a higher  
resolution.  
The default value (10) favors motion.  
Adjusting Video Encoder Quality  
You can adjust the quality of the video image sent to the far end during a call by specifying a relative lower or higher  
resolution in the Administrator Preferences : Video : Video Quality : Video Encoder Quality preference.  
Moving the slider to the right decreases the resolution of the video sent to the far end and improves the quality of the video  
image.  
3
Consider using this preference to make minor adjustments to the quality of the video image sent to the far end.  
Adjusting the MTU of Video Packets  
Video packets that exceed the maximum transmission unit (MTU) size for any router or segment along the network path may  
be fragmented or dropped. This results in poor quality video at the receiving device.  
You can set the MTU of video packets that your system sends.  
The default value is 1 440 bytes. The allowed range is 900 to1 500 bytes.  
To set the MTU for video packets, access Administrator Preferences : Video : Video Quality : Video MTU.

Near End Video Quality  
Before you place a call, examine the near end video image of the camera. If the image flickers, colors appear unbalanced, or the  
image appears too dark, you may need to adjust the room lighting or camera brightness and whitebalance.  
Placing a Call  
4
You can place a video or voice call with your VCS system in the following ways:  
•
•
Select a stored number from the REDIAL list on the main screen or from the directory.  
Manually dial a number using the Video Call or Voice Call buttons on the main screen.  
You can place a call with the IP addresses. This enables systems inside a corporate network without access to a gateway to call  
other systems in the network using system IP addresses.  
NOTE  
When microphone howling occurs during the Video or Voice call, the microphone will be shut off automatically and the icon  
for announcing that the microphone is shut off will appear on the lower right-hand corner of the screen automatically.  
Placing a Call from the REDIAL List  
The REDIAL list on the main screen stores up to 15 recently dialed numbers. A scroll bar appears when more than five entries are  
available for selection. The oldest entry in the list is automatically removed when the system receives a call after the maximum  
number of entries has been reached.  
The last call placed always appears at the top of the list. The entry includes the name of the system called and an icon that  
indicates whether the call was a voice  
appears below the list when the entry is selected. If the system receives a call, but does not answer it, the call appears in the  
REDIAL list as a missed call. The symbol appears next to the name in the entry. Select the entry to display the date and time  
or video  
call. The entry’s number (and bandwidth if the entry is a video call)  
of the missed call below the REDIAL list.  
To place a call from the REDIAL list, use the arrow keys on the remote control to select an entry and press OK.  
To change the bandwidth for a video call on the REDIAL list before placing the call, select Video Call on the main screen, press  
OK twice, and use the right arrow key to select the desired bandwidth from the list.  
Operation  
57  
NOTE  
•
•
•
•
Selecting Auto from the Video Call selection before placing a call does not change the bandwidth selection for an entry  
on the REDIAL list that does not have Auto as its last called bandwidth.  
You can adjust the maximum number of entries that appear in the REDIAL list by adjusting the [Maximum Redial  
Entries] preference in the User Preferences : Calls menu.  
The [None] option for the [Maximum Redial Entries] preference removes existing entries from the REDIAL list and  
prevents new entries from appearing on the list.  
You can also add entries from the REDIAL list to the local directory and manually remove entries or lock them to prevent  
them from being automatically removed when the maximum number of entries is reached. For more information, refer  
to“Managing the REDIAL List”on page 63.  
Placing a Call from the Directory  
The directory stores a list of names and numbers from which you can place calls. The directory includes three subdirectories: the  
local, corporate and meetings directories. The corporate directory is read only and managed by your administrator.  
4
Entries in the local directory are stored on the system and can be modified.  
To place a call from the directory, follow these steps:  
1. From the main screen, press the  
button on the remote control to access the directory.  
2. Use the arrow keys to select the Local, Corporate or Meetings directory and press OK.  
3. Use the arrow keys on the remote control to select the entry that you wish to dial.  
You can browse the directory using either the alphabetical or hierarchical method. When you use the alphabetical method,  
the entries appear in alphabetical order and you can select an alphabet group in the Browse column to quickly navigate to  
an entry. Hierarchies are predefined organizational units similar to folders or directories on a computer system. You can place  
an entry into a hierarchy when you create the entry or at any time by editing the Hierarchy field when editing the entry. For  
more information about creating hierarchies, refer to“Managing the Directory”on page 64. Using the hierarchical method,  
you can select a hierarchy in the Browse column to locate an entry. To move down one level in Browse, press OK. To move up  
one level, press the  
button. You can also use the  
and  
keys on the remote control to move up or down a page of  
entries when an entry is selected.

Check that the LED on front of the camera flashes bright blue when you use the remote  
control.  
The image is not visible.  
The sound is not audible  
Verify that the blue LED 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.  
If you are unable to hear the ringer when an incoming call arrives, adjust the Ring Tone  
Volume preference in User Preferences : Audio. Muffled audio reception from the far  
side may be caused by highly reverberant rooms. If you are experiencing poor audio  
reception, add more sound absorbency to the room and speak in close proximity to the  
microphone.  
Degradation in audio quality can also be caused by faulty microphones or dust and debris  
on the microphones. Do not use any kind of liquid or aerosol cleaner on the camera that  
includes microphones. A soft, slightly damp cloth is sufficient to clean the top surface of  
the units if necessary.  
Ensure both ends are not muted. Verify that the audio out cables are properly connected  
to the monitor and that any external speaker systems are powered and configured  
correctly.
