LifeSize UVC Multipoint Deployment Guide May 2014

LifeSize UVC Multipoint Deployment Guide 2 LifeSize UVC Multipoint LifeSize UVC Multipoint is a software MCU optimized for conferences that mix high definition video devices with desktop and mobile clients. The guide includes the following sections: Flexports and Capacity Deploying LifeSize UVC Multipoint Conferences Maintaining LifeSize UVC Multipoint Introduces flexports, resolution scale capacity, and machine capacity. Describes tasks to enable and configure the bridge. Describes how to create and manage conferences. Describes how to back up, restore, and reset the system and how to troubleshoot issues. If you are integrating UVC Multipoint with UVC ClearSea, refer to the LifeSize UVC ClearSea Deployment Guide for implementation details and instructions. Related documentation is available from lifesize.com/support. 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 call conference on demand conference scheduled conference fixed capacity flexible capacity flexport live port Virtual Operator State of the conference after the first participant joins. Individual participant who joins a conference. Conference with multiple participants, hosted by the bridge. Conference that is not scheduled in advance, has no scheduled start time, and is always live. Conference that is planned in advance and includes a specific participant capacity for a given start and end time. Capacity is fixed regardless of resolution. A 1080p port uses as much capacity as a 480p port. Capacity adjusts based on resolution. 1080p typically offers the least amount of capacity but the highest quality. 480p and below offer the most capacity. A licensed port that allows you to consume resources based on the conference resolution. Conference is available and ready to accept participants. On demand conferences are always live; participants need not join for a conference to be live. Used for conference connection ports that determine the number of simultaneous participants that can be hosted on a single conference. When enabled, answers calls to the bridge that do not specify a conference ID. Prompts you to enter the conference ID.

LifeSize UVC Multipoint Deployment Guide 3 Section 1: Flexports and Capacity Licensed flexports allow you to support a mix of high definition video devices and desktop or mobile clients. The number of required flexports is based on the resolution you select for the conference. Conference Resolution Number of Flexports Participants Video Audio 1080p30 2 1 7 720p30 1 1 3 480p30 1 2 2 360p30 1 4 0 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 on a UVC Multipoint licensed for 10 flexports. Conference A uses 1080p30 to host room systems. Conference B uses 720p30 to host room 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. Conference Call Scenario Licenses Consumed Available Remaining Ports Conference A: 1080p30 Conference B: 720p30 Conference C: 480p30 2 video calls 4 flexports 2 flexports remain, allowing one of the following: 2 video calls 2 flexports 1 1080p30 video call 4 audio-only calls 4 audio-only ports 2 720p30 video calls 4 480p30 video calls 4 video calls 2 flexports 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 4 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 will reduce 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 and frame rate for each active conference to lower levels. Resource rationing occurs in increments, attempting to reduce performance just enough to reduce the server load sufficiently. A new level of rationing occurs each time the server load exceeds 85 percent for approximately 20 seconds. The first two levels affect resolution. Original 1080p 900p 720p 640 560 512 480 464 400 360 336 288 Reduced 900p 720p 640p 560 512 480 464 400 360 336 288 240 The next three levels reduce frame rate to 20 f/s, 15 f/s, and 10 f/s, respectively. If server load again exceeds 85 percent, new calls are rejected and you can no longer move participants between conferences. Finally, if server load again exceeds 85 percent, the bridge drops the last 20 percent of the participants to join in increments every 20 seconds until the load drops below 60 percent. Conversely, if the server load for a sustained amount of time stays below 60 percent of the maximum load, UVC Multipoint reverses the process to improve 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 is reduced from 30 f/s to 20 f/s and onscreen overlays and indicators do not display.

LifeSize UVC Multipoint Deployment Guide 5 Section 2: Deploying LifeSize UVC Multipoint Deploying UVC Multipoint includes the following tasks: Prepare firewalls. Complete installation and initial configuration. Check for software updates and upgrade to the latest versions to ensure they are compatible. Configure UVC Multipoint. Optional: Use the REST API to control UVC Multipoint. Configuring your Firewall Initial Configuration LifeSize UVC Platform Installation and Deployment Guide Configuring Your Network Configuring H.323 Configuring SIP Access API documentation at http:// <UVC_Multipoint_IP_address>/uvcmcu/docs/native/ Configuring your Firewall If your LifeSize system communicates with other systems through a firewall, you must configure your firewall to allow incoming and outgoing traffic to the system through the following ports: TCP port 1720 UDP port 1719 UDP port 5060 TCP port 5060 TCP port 5061 H.323 call setup SIP call setup SIP call setup if TCP signaling is enabled for SIP calls TLS signaling in SIP calls if TLS signaling is enabled Reserved TCP and UDP ports Default range 60000-64999 80 (HTTP) 443 (HTTPS) Administration ports

LifeSize UVC Multipoint Deployment Guide 6 Firewall Traversal Three methods of firewall traversal are available. 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. UVC Transit If UVC Multipoint is deployed in the DMZ or Internet, alone or with UVC Transit Server, callers outside your network must use the public IP address of UVC Access to place calls to your video systems. Refer to the LifeSize UVC Transit Deployment Guide. Multiple network interfaces Single network interface with static NAT 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. Video devices in the network can call the private IP address. External video devices can call the static NAT IP address. Initial Configuration Perform initial configuration on UVC Platform. Complete the following procedures 1. Install UVC Platform. 2. Activate a licence for UVC Multipoint. Read more LifeSize UVC Platform Installation and Deployment Guide 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 Create additional administrator accounts as described in step 5.

LifeSize UVC Multipoint Deployment Guide 7 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. 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. 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. 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. 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.

LifeSize UVC Multipoint Deployment Guide 8 5. Optional: Create an administrator account for UVC Multipoint. a. Navigate to User Management > Users Add. b. Enter a username and password. c. Click Save. d. In Multipoint Server Permissions, select Multipoint Administrator. e. Click Save. 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 Audio, video, and data priority IntServ ToS Video MTU Reserved UDP and TCP Ports Choose the type of TCP/IP QoS that your network uses: IP precedence or DiffServ. By default, this preference is set to Off. Specify the priority of audio, video, and data for Network QoS. Choose the type of service for IP precedence. By default, this preference is set to None. 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. 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. : BFCP uses the lowest configured UDP and TCP ports.

LifeSize UVC Multipoint Deployment Guide 9 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. 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. 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.

LifeSize UVC Multipoint Deployment Guide 10 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. 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. Icons indicate the status of the registration process. H.323 SIP and Microsoft Lync Description Registered Registering Unable to reach the gatekeeper or SIP registrar Registration Failed Configuring the Virtual Operator Enable the Virtual Operator for participants who call in to UVC Multipoint without specifying a conference ID or who use an invalid conference ID. 1. Access Preferences > Virtual Operator and select the checkbox to enable the operator. 2. To allow users interacting with the Virtual Operator to create a temporary conference, select Allow users to create conferences. The on demand conference is removed two minutes after the last participant exits the call. 3. Enter a name for the operator, which appears in the caller ID and redial lists. 4. Select a language.

LifeSize UVC Multipoint Deployment Guide 11 Conference and Video Settings Define the following global conference settings in Preferences > Conferences: number of digits in conference IDs range of conference IDs maximum number of on demand conferences interval after which conferences are removed presentation bandwidth percentage of the total bandwidth available for the primary and presentation streams 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 Forward error correction 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.

LifeSize UVC Multipoint Deployment Guide 12 Section 3: Conferences UVC Multipoint supports on demand and scheduled conferences. Microsoft Lync clients can be participants in both types of conferences. Refer to Microsoft Lync Conferences. On demand conferences Scheduled 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 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. Conferences use either shared or dedicated encoders: Shared encoders Dedicated 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. 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. Creating Conferences 1. To create an on demand conference, click Conferences >. To create a scheduled conference, click Scheduler and double-click the desired date for the conference. 2. By default, UVC Multipoint assigns the next available conference ID. To enter a different ID, clear the Auto checkbox. 3. Enter a name for the conference. 4. Enter a description of the conference.

LifeSize UVC Multipoint Deployment Guide 13 5. Optional: Enter a password that users must enter to join the conference. Select Show Password to include the password in the meeting invitation. Passwords must be 20 numeric characters or fewer. Passwords must be 8 numeric characters or fewer for conferences you create in the Virtual Operator. 6. Enter the number of Maximum Participants. The maximum value depends on your server capacity, the conference resolution, and the value of Encoder sharing. Ensure that you consider these factors when determining the maximum value for optimal performance in your configuration. - Scheduled conference only: Reserves the necessary port resources. - On demand conference only: Limits the number of video participants who can join the conference. The default value of Auto limits the number of video participants to the maximum value. 7. Scheduled conference only. Select All Day or adjust the time frame for the start and end date and time. 8. Optional for a scheduled conference only: Choose an option for a conference that repeats. 9. To set additional preferences, click Advanced settings: Preference Description Default Value Resolution Maximum video resolution for the conference. Choose 1080p, 720p, 480p, or 360p. This setting determines the flexport consumption rate. Refer to Flexports and Capacity. Note: If you select 360p, you can enable the Increase Capacity option to reduce resource usage when the system load is high and allow additional callers. Frame rate is reduced and on screen overlays and indicators do not display. 720p Default layout Audio codecs Video codecs Presentation codecs Participants Default layout to use for the conference. Choosing a layout other than Auto prevents individual callers from changing the layout during a conference. Read more at Managing Layouts. Customize the default audio codec order, or allow the system to choose automatically. Customize the default video codec order, or allow the system to choose automatically. Customize the default presentation codec, or allow the system to choose automatically. A list of participants to add to a conference. In a scheduled conference, these participants are dialed when the conference becomes live. In an on demand conference, all participants are dialed when one participant dials the conference, making it active. If you prefer that participants must dial in individually, do not define any participants in this list. Auto Auto Auto Auto None

LifeSize UVC Multipoint Deployment Guide 14 Preference Description Default Value Presentation bandwidth Encoder sharing Self view User control Adjusts the bandwidth allocated to presentation video as a percentage of the total available bit rate for both primary and presentation video. The default value is 20% for the presentation stream. Set the bandwidth balance globally in Preferences > Conferences. : Changing the presentation bandwidth percentage does not affect ongoing presentations. To use the new value, restart the presentation. Not available when UVC Multipoint is registered to a Microsoft Lync server. Enabling Encoder sharing allows for more participants but also lowers video quality to that of the participant with the lowest quality video. (Only when Encoder sharing is On.) The view from a participant s camera appears on their screen. (Self view is always on in shared encoder conferences.) (Only when Encoder sharing is Off.)

Moving a Participant To move a participant from one conference to another, click and drag the participant. The participant immediately drops from the current conference and joins the other conference. If you move a participant sharing a presentation, the presentation immediately ends. Do not attempt to move a Lync participant to a conference that is not registered to a Lync server, and therefore, does not support Lync participants. The Lync participant s call terminates. 15

LifeSize UVC Multipoint Deployment Guide 16 Modifying Conferences in the Scheduler To modify a scheduled conference, double-click the conference name. Changing options from the Scheduler in an active conference does not affect participants. Use the Conferences tab to make immediate changes to an active conference. Managing Layouts You can choose a specific layout for the conference or you can use Auto, the default. Set or change this preference when you create the conference or when it is idle. If you choose a layout other than Auto when you create the conference, the video layout is locked for each participant. An administrator can change the layout for all participants or for an individual participant (if Encoder sharing is turned off). To make temporary layout changes during an active conference, click >. When the layout is set to Auto, the first participant is shown full screen. When a second participant joins the conference, the layout switches to two large side-by-side windows bordered by four smaller windows on the top and on the bottom of the screen. The two most recent talkers are featured in the large windows, with participants who spoke less recently moving to the smaller screens. When a fourteenth participant joins the conference, the layout switches to 4 x 4 windows. The layout does not progress beyond the 4 x 4 layout automatically. You must explicitly choose the 5 x 5, 6 x 6 and 7 x 7 layouts. All layouts are available regardless of the conference capacity.

LifeSize UVC Multipoint Deployment Guide 17 In conferences with more participants than windows, the least recent talkers move off screen until they speak again. The number of video callers who are not visible and the total number of audio callers appear on the bottom left of the window. Video quality might be reduced in 5 x 5 layouts and greater in 720p and 1080p conferences. Limit conferences using these layouts to 480p.
