Enabling Telepresence
You can set the system to telepresence mode in whi\Bch a conference administrator controls calls from a control panel (such as \B
LifeSize Control or the Call Manager in the web administration in\Bterface).
Enabling telepresence removes the user interface from view. When the system is idle, only the background image appears\B in the 
display. \fn administrator can access the u\Bser interface by pressing OK and entering the administrator password.
During a call, users see the vid\Beo from the call and the \Bmute indicators. The navigation bar, PIP windows, caller ID information, 
and call status mess\Bages do not appear \Bon the screen. 
Users can invoke the Call Manager dialog and \Bcall statistics and c\Bhoose video inputs \Bwith the remote control. The numeric keys 
on the remote control play touch tones. Users can change\B this behavior from the Call Manager.
To enable or disabl\Be telepresence and lock or\B unlock cameras, configure preferences in Admi\bist\fato\f P\fefe\fe\bces : 
Telep\fese\bce.
Configuring Communications Preferences
You can specify opti\Bons that control which protocols the system uses during calls by configuring preferences in Admi\bist\fato\f 
P\fefe\fe\bces : Commu\bicatio\bs.

Configuring Dialing Op\Ttions
You can choose voice and video dia\Bling options during the initial confi\Bguration, when performing a system reset, or at any 
other time by accessing Admi\bist\fato\f P\fefe\fe\bces : Commu\bicatio\bs : Ge\be\fal. 
Receiving Presentations
This system can receive and initiate presentations during a call through a secondary H.239 media chan\Bnel. 
By default, the presentation function is enabled. 
To disable presentations access Admi\bist\fato\f P\fefe\fe\bces : Commu\bicatio\bs : Ge\be\fal : P\fese\btatio\bs.
Consider disabling \Bthe presentation function if your system experiences interoperability issues with third party systems that 
do not support presentations.
NOTE
Vi\ftual Li\bk (Data Sha\fi\bg)
Virtual Link allows this system to share IP-based presentation data during call. 
For the most current product information, including a\B summary of new features, resolved and known issues, 
interoperability with third party products, and documentation \Berrata, refer to the Release Notes at www.lifesize.com/
support.
Specifying H.323 Settings
By default, this system supports the H.323 protocol for placing and receiving video and\B voice calls. 
You can disable sup\Bport for H.323 calls by selecting Disabled for the H.323 preference in Admi\bist\fato\f P\fefe\fe\bces : 
Commu\bicatio\bs : H.323 when the system is not in a call\B. 
If you choose Disabled\B for the H.323 preference, the system cannot place or \Breceive calls with the H.3\B23 protocol.
NOTE
If both H.323 and SI\BP preferences are set to Disabled, a warning message appea\Brs and indicates that video calls \Bcannot be 
placed or received with this configur\Bation.
When H.323 is enab\Bled, you can specify an \BH.323 name or extension to use when placing\B a call. The H.323 name and \B
extension identify the \Bdevice to the gatekeeper. \fny registered device can dial anoth\Ber one using this n\Bame and extension. 
The H.323 Name preference is an optional\B value that is used \Bwhen a gatekeeper is configured and requires the system to 
register with an H.323 ID\B. 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\B value that is used \Bwhen a gatekeeper is configured and 
requires the system to register with an E164 num\Bber or extension. If the gatekeeper administrator assigns an E164 number \Bor 
extension for the system, enter that number for the H.323 Extension preference.
Set the \batekeeper ID only if th\Be gatekeeper requires it (for example, configurations with\B multiple gatekeepers). The 
\batekeeper 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 \batekeeper Mode preference to \futo if you wish to have the system automatically discover a gatekeeper. You can 
also set the \batekeeper Mode preference to Manual to manually choose \Ba gatekeeper. If set to Manual, specify the IP add\Bress 
and port for the primary gatekeeper. 
When you select the Register button in Admi\bist\fato\f P\fefe\fe\bces : Commu\bicatio\bs : H.323, icons appear in \Bthe status 
bar to indicate the status of the r\Begistration process with the H.323\B 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  appears. If the system 
is registered to a gatekeeper, the system displays its status.
Configuring a secondary H.323 gatekeeper with the \batekeeper IP \fddress 2 and \batekeeper Port 2 preferences is optional.

Enabling H.460 Support for H.323 Calls
This system supports the H.460 protocol for firewall and N\fT traversal of H.323 cal\Bls. 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\B enable H.460 supp\Bort, the system ignores preferences in Admi\bist\fato\f P\fefe\fe\bces : 
Netwo\fk : NAT.
To enable H.460 cli\Bent support on a system, configure the H.323 preferences in Admi\bist\fato\f P\fefe\fe\bces : 
Commu\bicatio\bs : H.323 with the following exceptions:
• Choose Manual for the \batekeeper Mode preference.
• For the \batekeeper IP \fddress 1 and \batekeeper Port 1 preferences, enter the IP address and port number of the H.46\B0 
server that is configured in your environment.
• Choose Enabled for the H.460 preference.
• Navigate to Register and click OK. 
NOTE
If you enable H.460 an\Bd specify the IP add\Bress and port number of a secon\Bdary gatekeeper with the \batekeeper IP 
\fddress 2 and \batekeeper Port 2 preferences, the system ignores the secondary gatekeeper.   
Configuring SIP Settings
By default, support for Session Initiation Protocol (SIP) is enabl\Bed on the system. To configure SIP as the protocol to use for 
placing calls, configure SIP preferences in Admi\bist\fato\f P\fefe\fe\bces : Commu\bicatio\bs : SIP. You can also disabl\Be support 
for SIP by choosing Disable\Bd for the SIP preference when the system is not in a call\B. 
If you choose Disabled\B for the SIP preference, the system cannot place or \Breceive calls with the SIP\B protocol.
NOTE
If both H.323 and SI\BP preferences are set to Disabled, a warning message appea\Brs and indicates that video calls \Bcannot be 
placed or received with this configur\Bation.
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 sys\Btem uses for authentication; th\Bese values are only required if the registrar or proxy 
require authentication.
If you are planning on plac\Bing and receiving calls on \Bthis system with Microsoft Office Communications Server, 
L\b recommends that admin\Bistrators choose Microsoft OCS for SIP Server Type in Admi\bist\fato\f P\fefe\fe\bces : 
Commu\bicatio\bs : SIP. The default is \futo. For more information about using M\Bicrosoft OCS with LifeSize communications 
devices, refer to the technical note on the Support page of www.lifesize.com.
You can change the c\Bommunication 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 \Bthe status bar to indicate the status of the r\Begistration 
process with the SIP s\Berver. 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 S\BIP UDP signaling port. You can also enable\B TCP signaling and change \Bthe TCP signaling port. You can 
enable Transport Layer Security ( TLS) signaling and change \Bthe 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\B the other. Choosing 
Disabled for the SIP Registrar preference automatically disables\B TLS signaling. If neither TCP nor TLS signaling is enabled, only 
UDP signaling is enabled.

Installation
NOTE
The system reboots if you change the UDP si\Bgnaling port, enable or disabl\Be 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 supp\Borts SRTP, the media is encr\Bypted and encryption icons appear\B in the caller ID, Call Manager list, and Call 
Statistics list in the\B user interface during a call. Refer to “Caller ID” on page 59 for a description of the icons. 
If the far end does \Bnot support SRTP, the media is not e\Bncrypted and call encryption icons do not \Bappear in the user \B
interface.
Configuring \fppearance Preferences
Users can configure preferences in Use\f P\fefe\fe\bces : Appea\fa\bce and Backg\fou\bds that affect the appearance or \Bbehavior 
of the following:
• screen saver that appears when\B the system is idle and the \Bscreen saver timeout
• system sleep timeout
• timeout interval for the appearance o\Bf the user interface after a call connects
• language in which \Bthe user interface appears
• background image or colo\Br that appears in the\B user interface
Help text appears at the bottom of the screen to assist users in s\Belecting an option for each preference. \fdministrators can also 
access these preferences in Admi\bist\fato\f P\fefe\fe\bces : Ge\be\fal, Backg\fou\bds, and Layout. 
To hide or show L\b&LifeSize branding, access Admi\bist\fato\f P\fefe\fe\bces : Appea\fa\bce : Ge\be\fal : Compa\by Logo. 
Choose None to hide the branding\B. The Default option shows the branding. 
Video Layout Preferences
\fll users can config\Bure the Picture In Picture video layout preference in Use\f P\fefe\fe\bces: Appea\fa\bce. Refer to “Managing 
PIP” on page 60 for more information about setting \Bthis preference.

Configuring Display Pr\Teferences
Only administrators can configure preferences that affect display types, resolutions, and energy management option\Bs. 
Display preferences appear in Admi\bist\fato\f P\fefe\fe\bces : Appea\fa\bce : Displays. Typically, you configure display 
resolutions when you install your system or change a dis\Bplay and to troubleshoot display issues. 
You can set the Displ\Bay 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.
L\b 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 si\Bgnal and show text indicating this sta\Bte. This may result in the text image burning 
into the screen. Some displays may recognize the loss of the si\Bgnal and power off, but then not wake up when the system 
wakes up.
Configuring Video Behaviors
\fdministrators can adjust vide\Bo behaviors to control cameras and vid\Beo quality by configuring preferences in Admi\bist\fato\f 
P\fefe\fe\bces : Video.
Controlling the Camera Use by Far End Users
To prevent far end users f\Brom controlling your PTZ near end ca\Bmera, including co\Bnfiguring and controlling camera presets, 
choose Disabled for the Admi\bist\fato\f P\fefe\fe\bces : Video : Video Co\bt\fol : Fa\f Co\bt\fol of Nea\f Came\fa preference. If 
you choose Enabled, you can still prevent far end users f\Brom configuring and using near\B end camera presets by choosing 
Disabled for the Far Set of Camera Presets and Far Move to Camera Presets preferences.
Locking the Camera Presets
By default, all user\Bs can configure PTZ camera presets. To prevent all users (near\B and far end) from configuring camera 
presets, select Locked for the Admi\bist\fato\f P\fefe\fe\bces : Video : Video Co\bt\fol : Came\fa P\fesets Lock preference. 
To prevent only far end us\Bers from configuring camera presets, choose Disabled \Bfor the Far Control of Near Camera or Far Set 
of Camera Presets preferences.
Customizing Input Device Names
You can define a cus\Btom input name by changing the default valu\Be for HD Camera 1 Name in Admi\bist\fato\f P\fefe\fe\bces : 
Video : Video Co\bt\fol. Customized names are limited to 16 characters. 
The default name is \BHD Camera 1.

Selecting Priority of Quality Metrics for Source Video
You can favor sharpness or motion as \Ba priority for the quality of primary video that the syst\Bem sends to the far end during a 
call. 
If you favor sharpness by selecting a smaller numb\Ber for the Admi\bist\fato\f P\fefe\fe\bces : Video : Video Quality : P\fima\fy 
Video Motio\b preference, in lower bandwidth calls \Bthe system sends the primary video at a lower frame rate and a higher 
resolution. 
The default value (1\B0) favors motion.
\fdjusting Video Encoder Quality
You can adjust the qu\Bality of the video imag\Be sent to the far end during a call by specifying a relative lower or higher 
resolution in the Admi\bist\fato\f P\fefe\fe\bces : Video : Video Quality : Video E\bcode\f Quality preference. 
Moving the slider to the right decreases the resolution of the vid\Beo sent to the far end and i\Bmproves the quality of the video 
image.
Consider using this \Bpreference to make minor adjustments \Bto the quality of the video imag\Be sent to the far end.
\fdjusting the MTU of Video Packets
Video packets that exceed the maximum tra\Bnsmission unit (MTU) size for any router or segment along the network path may 
be fragmented or dropped. This results in poor qual\Bity video at the receiving device. 
You can set the MTU of video packets that your system sends. 
The default value is\B 1 440 bytes. The allowed range is 900 to1 500 bytes. 
To set the MTU for video packets, access Admi\bist\fato\f P\fefe\fe\bces : Video : Video Quality : Video MTU.
Record and Stream
“Record and Stream” in Admi\bist\fato\f P\fefe\fe\bces : Video is related to use of the LifeSize Video Center which is a network 
server that stores and streams video sent by LifeSize video communicati\Bons systems enable for streaming and recording.
Viewers access these vi\Bdeos and live streams from the server through a browser-based interface on the computers.
