Terminology
The following terms are used in this document to describe UVC Multipoint features. These terms might
differ from terms used with other Lifesize video systems. Familiarize yourself with these terms to best
understand the capabilities of your UVC Multipoint.
active
State of the conference after the first participant joins.
call
Individual participant who joins a conference.
conference
Call with multiple participants, hosted by the bridge.
on-demand
conference
Live conference that is not scheduled in advance and has no scheduled start time.
scheduled
conference
Conference that is planned in advance and includes a specific participant capacity for a given start
and end time.
fixed
capacity
Capacity is fixed regardless of resolution. A 1080p port uses as much capacity as a 480p port.
flexible
capacity
Capacity adjusts based on resolution. 1080p typically offers the least amount of capacity but the
highest quality. 480p and below offer the most capacity.
flexport
A licensed port that allows you to consume resources based on the conference resolution.
live
Conference is available and ready to accept participants. On-demand conferences are always live;
participants need not join for a conference to be live.
port
Used for conference connection ports that determine the number of simultaneous participants that
can be hosted on a single conference.
Virtual
Operator
When enabled, answers calls to the bridge that do not specify a conference ID. Prompts you to
enter the conference ID.

For example, a UVC Multipoint licensed for 10 flexports is capable of hosting a total of 40 video and audioonly calls in one of the following configurations:
•
Five 1080p30 video calls and 35 audio-only calls
•
Ten 720p30 video calls and 30 audio-only calls
•
Twenty 480p video calls and 20 audio-only calls
Flexports also allow you to host multiple conferences with different resolutions. In the following example,
three conferences are scheduled using UVC Multipoint licensed for 10 flexports. Conference A uses
1080p30 to host video systems; Conference B uses 720p30 to host video systems and desktop, phone, or
tablet clients; Conference C uses 480p30 to host desktop and mobile clients. The bridge divides its
capacity according to the needs of the conferences.

2 video calls
2 flexports
4 audio-only calls
4 audio-only ports
Conference C:
480p30
4 video calls
2 flexports
• 1 1080p30 video call
• 2 720p30 video calls
• 4 480p30 video calls
• 28 audio-only calls
If Conference C adds 4 video calls (using the remaining 2 flexports), the bridge can host a total of 12 video
participants.

Lifesize UVC Multipoint Deployment Guide
Capacity and Resource Rationing
The actual capacity of your UVC Multipoint relies on machine capacity and how conferences are used,
especially with a mix of shared encoder, dedicated encoder and Microsoft Lync conferences occurring
simultaneously. Conference bandwidth also affects capacity. Some third party video devices might require
more bandwidth to operate at the selected resolution, which reduces overall capacity.
UVC Multipoint allows administrators to over provision their flexport licenses to support single, high
capacity conferences, and to support virtual machine migration from lower capacity servers to higher
capacity servers. However, over provisioning can overload the server, and when it does, UVC Multipoint
rations its resources to ease the server overload. When the server exceeds 85 percent of the maximum
load for a defined time, UVC Multipoint reduces the resolution, frame rate or call capacity for each active
conference.
Resource rationing occurs incrementally, with the goal of reducing performance just enough to lighten the
server load and avoid affecting call quality. Different levels of rationing are enforced when the server load
exceeds 85 percent for approximately 20 seconds, including:
•
Reducing the frame per second (f/s) rate
•
Reducing resolution*
•
Rejecting new calls
•
Dropping callers until the server load falls to acceptable levels.
The table shows the progression of rationing, based on your conference resolution setting.

Lifesize UVC Multipoint Deployment Guide
As the server load improves, UVC Multipoint reverses the progression and improves performance, level by
level.
When rationing occurs, the rationing level is indicated on the dashboard. When rationing occurs to the
extent that calls cannot be added,
appears.
Lifesize recommends that you migrate your UVC Multipoint installation to a higher capacity server when
rationing occurs regularly.
Increasing Capacity
If you choose 360p for the maximum video resolution for the conference (when creating a conference in
Advanced settings), you can also choose the Increase Capacity option to reduce resource usage when
the system load is high, and therefore allow additional callers. Frame rate per second (f/s) is reduced from
30 f/s to 20 f/s and on-screen overlays and indicators do not display.

Lifesize UVC Multipoint Deployment Guide
Firewall Traversal
Three methods of firewall traversal are available.
NOTE
Using more than one traversal method is not supported. For example, you
cannot configure an IP address with static NAT if you configure UVC
Multipoint with two network interfaces.
Multiple network
interfaces
Configure one interface with the private IP address and the second interface with the
public IP address.
Read more about multiple network interfaces in the Lifesize UVC Platform Installation
and Deployment Guide.
Single network interface
with static NAT
Video devices in the network can call the private IP address. External video devices
can call the static NAT IP address. Enabling or disabling this feature in UVC Platform
requires you to restart UVC Multipoint.
Initial Configuration
Perform initial configuration on UVC Platform.
Complete the following procedures

1. Install UVC Platform.
Lifesize UVC Platform Installation and Deployment Guide
2. Activate a license for UVC Multipoint.
3. Enable UVC Multipoint.
Enabling Lifesize UVC Multipoint
4. Ensure that you can access the interface
from your private network.
In a browser, enter the IP address or fully qualified domain name
of UVC Multipoint on HTTPS:
https://lifesize_UVC_multipoint_IP_address/uvcmcu/
https://multipoint.example.com/uvcmcu/
Enabling Lifesize UVC Multipoint
1. Open a browser and log in to UVC Platform. The default administrator credentials for UVC Platform
and all enabled applications are:
Username: administrator
Password: admin123
NOTE
Create additional administrator accounts as described in step 5.
7
Lifesize UVC Multipoint Deployment Guide
2. Ensure sufficient IP addresses are available.
A dual home configuration (using the LAN and WAN network interfaces) requires two static IP
addresses. The WAN interface must use a public IP address.
NOTE
Lifesize strongly recommends that you configure the LAN and WAN on
different subnets.
Add an IP address as follows:
a. Navigate to System Settings > Network Settings > IP addresses – Edit.
b. Click Add address.
c. Enter the new IP address.
If you are configuring an IP address that uses 1:1 static NAT, enter the public IP address in NAT
public IP address. If you add or remove a 1:1 static NAT configuration, you must reboot UVC
Multipoint.
NOTE
You cannot use a 1:1 static NAT address in a dual home configuration.
Press Tab to automatically complete the remaining values, or enter each remaining value. Review
any values entered by the server.
d. Click Apply Changes.
3. If you are using both network interfaces, navigate to System Settings > Network Settings > IP
addresses > Default gateway – Edit to ensure that the default gateway is set on the correct interface.
When you first install UVC Platform, you set the default gateway to the address in the network set
eth0 console command.
Typically, you set the default gateway on the WAN interface and configure static routes for the LAN
interface to route traffic to all known LAN address ranges through the gateways specified in the static
routes. Configure a static route in System Settings > Routes – Add Route. Enter the LAN IP address
in Destination.
If you are using a LAN/LAN configuration, you set the default gateway on one of the networks and use
static routes for the other network.
4. Enable UVC Multipoint. Ensure port 8180 is open to your UVC Platform.
NOTE
You must activate a license for UVC Multipoint before performing these steps.
Refer to the Lifesize UVC Platform Installation and Deployment Guide.
a. Navigate to Operations and Maintenance > Applications enabled – Edit.
b. In Enable new application, select Multipoint.
c. Select one or two IP addresses.
d. Click Enable application.

Configuring Lifesize UVC Multipoint
Changes to preferences that cause the system to restart prompt you to verify the change. You cannot
change preferences that disconnect calls in progress. Change those preferences when the system is idle.
Configuring Your Network
To configure preferences that affect how your system functions with other servers and devices on your
local network, navigate to Preferences > Network.
Network QoS
Choose the type of TCP/IP QoS that your network uses: IP precedence or DiffServ. By
default, this preference is set to Off.
Audio, video, and
data priority
Specify the priority of audio, video, and data for Network QoS.
IntServ ToS
Choose the type of service for IP precedence. By default, this preference is set to None.
Video MTU
Video packets that exceed the MTU size for any router or segment along the network path
may be fragmented or dropped, resulting in poor quality video at the receiving device. Set
the MTU of video packets that your Lifesize system sends. The default value is 1440
bytes. The valid range is 800 to 1500 bytes. Lifesize recommends that you do not change
this value unless your network requires a different MTU.
Reserved UDP and
TCP Ports
By default, Lifesize systems communicate through UDP and TCP ports in the range 60000
- 64999. Lifesize recommends that you use the default range. However, you can restrict
the range of UDP and TCP ports that are available for communication. Valid values are in
the range 25000 - 65535.
NOTE: BFCP uses the lowest configured UDP and TCP ports.
9
Lifesize UVC Multipoint Deployment Guide
Configuring H.323
By default, the H.323 protocol is enabled on UVC Multipoint for placing and receiving video and voice calls.
To disable support for H.323 calls, clear Enable H.323 in Preferences > H.323.
NOTE
If both H.323 and SIP are Disabled, calls cannot be placed or received.
When H.323 is enabled, you can specify an H.323 name or extension. The H.323 name and extension
identify the device to the gatekeeper. Any registered device can dial another using this name and
extension. The H.323 name and H.323 extension preferences are optional values that a configured
gatekeeper uses, requiring the system to register with an H.323 ID or register with an E.164 number or
extension.
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. Select Enable authentication and enter the authentication username and
password.
Set Gatekeeper mode to Auto to allow the system to automatically discover a gatekeeper. You can also
set Gatekeeper mode to Manual to specify the IP address and port for the primary gatekeeper. The
default port is 1719.
When you click Apply, check Gatekeeper status to verify that UVC Multipoint registered to the
gatekeeper.
Configuring SIP
By default, support for SIP is enabled. To disable SIP calls, clear Enable SIP in Preferences > SIP.
NOTE
If you are registering to a Microsoft Lync Server, refer to Microsoft Lync
Conferences.
To use a SIP registrar, select Use SIP registrar, choose Auto for SIP server type, enter the Registrar
hostname, and specify the registrar port, 5060 by default. If the registrar requires authentication, enter the
bridge’s SIP username, Authorization username and Authorization password for the registrar. When
you click Apply, check Registrar status to verify that UVC Multipoint successfully registered to the
registrar.
To use a SIP proxy server, select Enable the SIP proxy server, enter the Proxy hostname, and specify
the proxy port, 5060 by default. Click Apply.
10
Lifesize UVC Multipoint Deployment Guide
Ports
UDP and TCP signaling are enabled, set to port 5060, and cannot be disabled.
If you enabled the use of a SIP registrar, you can select Use TLS. Direct SIP TLS calls are not supported.
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.
NOTE
The system restarts if you enable or disable TLS or SIP and click Apply.
Registering Individual Conferences
1. Provision the conference ID on the H.323 gatekeeper, SIP registrar or Lync server.
2. Set Register to On in the conference preferences. Conferences attempt to register to the gatekeeper,
SIP registrar, or Microsoft Lync server on which they have been provisioned. The following icons
indicate the status of the registration process.

•
presentation bandwidth percentage of the total bandwidth available for the primary and presentation
streams
NOTE
Changing the presentation bandwidth percentage does not affect ongoing
presentations. To use the new value, restart the presentation.
Define the following global video settings in Preferences > Video:
Default aspect ratio
Choose between 16 x 9 and 4 x 3 as the default aspect ratio to send to
participants whose supported aspect ratio cannot be determined.

Automatic recovery from video packet loss improves video reproduction. For
packet loss of 5% or less, this feature eliminates or greatly reduces video
artifacts. This feature is enabled by default.
12
Lifesize UVC Multipoint Deployment Guide
Section 3: Conferences
UVC Multipoint supports on-demand, scheduled and standard or lecturer-based conferences. Microsoft
Lync clients can be participants in all types of conferences. Refer to Microsoft Lync Conferences.
On-demand
conferences
On-demand conferences have no start or end times, are always live, and can be dialed
directly using a fixed conference ID. You can create up to 100 on-demand conferences,
by default. Read more at Conference and Video Settings.
Scheduled
conferences
Scheduled conferences have a specific start and end time, and ports are allocated by
participant.
The Scheduler manages the scheduling of ports and ensures that no conflicts exist. Each
participant in a conference uses one port. You can choose a minimum of 2 and up to the
maximum number of ports licensed on your bridge for the conference.
Scheduled conferences take priority over on-demand conferences, and port conflicts are
always settled in the scheduled conference’s favor. If a scheduled conference becomes
active, and on-demand conferences are using ports the scheduled conference needs, the
on-demand conferences terminate to free the necessary ports for the scheduled
conference.
Standard or lecturerbased conferences
Standard conferences offer standard camera views and controls. Lecture-based
conferences limit camera views and controls to simulate a classroom environment where
the conference leader controls participants’ views. In a lecture-based conference,
participant views are locked to focus on the lecturer. The lecturer sees all participants’
video and can share a presentation, if desired. If a lecturer leaves a conference while it is
in-progress, participants revert to a self-camera view with unmuted audio. When the
lecturer returns, the view automatically resets to lecture only and participant audio is
muted. For more information about creating a lecturer-based conference, see Select a
conference type: Standard or Lecturer.
NOTE: Lecture-based conferences are not supported on shared encoders.
Conferences use either shared or dedicated encoders:
Shared encoders
Two encoders are used per conference.
• 1080p or 720p conferences: Participants joining the meeting above 400 Kb/s share
the high quality encoder. Participants joining below 400 Kb/s share the low quality
encoder.
• 480p or 360p conferences: Participants joining the meeting above 128 Kb/s share
the high quality encoder. Participants joining below 128 Kb/s share the low quality
encoder.
Participants on a shared encoder all see the same layout, including their own video. The
lowest video quality connection on a shared encoder determines the video quality for all
participants. Shared encoder conferences lend themselves to conferences with many
participants.
Dedicated encoders
Each participant is assigned an encoder. The video connection quality of one participant
does not affect the quality of other participants. Self view is optional and each participant
can select their own layout.

Section 4: Maintaining Lifesize UVC Multipoint
Back Up, Restore, Reset, Restart
Navigate to System to maintain UVC Multipoint:
•
Create a backup file.
•
Restore from a backup file.
•
Reset the service to factory defaults.
•
Restart the bridge.
These options disconnect current calls. UVC Multipoint does not offer a maintenance mode that prevents
users from using the bridge. Choose a maintenance window when calls are unlikely to occur.
Restore the system to a valid backup file only. Restoring to a backup file created from previous software
versions might produce unexpected results. UVC Multipoint restarts after it restores the backup file.
