3 XV3000 MCU User's Guide Page 3 of 23 Product Description The XV3000 MCU is a multi-point video conferencing system comprised of a Xorcom IP-PBX and SIP-based video/audio conferencing services. Its Web-based management system provides users with a real-time tool for easy system configuration, conference creation, monitoring and conference control. The XV3000 MCU offers the following main video/audio capabilities: HD Conferencing: Wide-band high definition (HD) voice, and HD video in resolutions of up to 720p. Transcoding: dvanced transcoding and transrating capabilities provide participants with video and audio formats optimized for use with their specific end device, including codec type, frame rate, frame size and screen resolution. Video/voice Specifications: Voice codecs: G711a, G711u, G729, G723, G722.1, ilbc Video codecs: MPEG4, H263, H264 Video resolution: QCIF, CIF, VG, 4CIF and HD (720p) Leader-based Conferences: conference may be managed by a leader, or defined as an un-managed adhoc conference. Configurable Meeting Rooms: Meeting rooms (for impromptu conferences) may be provisioned and established for use at any time. Multiple Video Layout Options: 10 video dynamic layouts are available for equal-presence display and 5 for dominant-based display. When a participant enters or leaves the conference the layouts are reset automatically. VIP Participants: The XV3000 MCU allows pre-defined VIP participants to join a conference without requiring PIN code authentication. Registration on a SIP Server: s an optional feature, the XV3000 MCU can register the access numbers and/or conference room numbers on a SIP server. In addition, SIP clients can optionally register on the MCU built-in SIP server. Leader Dashboard: The XV3000 MCU provides a leader dashboard to enable a designated conference leader to control the conference by inviting or removing participants and modify conference parameters (mute, set dominant speaker, etc.). Product Components The XV3000 MCU is comprised of an IP-PBX and video/audio conference Multipoint Control Unit (MCU). IP-PBX The XV3000 MCU includes Elastix 2.x powered software with optionally installed E1/T1 interfaces. s with other Xorcom sterisk-based IP-PBX appliances, it is possible to connect one or more external stribank devices via USB 2.0 cables to provide additional telephony interfaces in the system. MCU The video/audio MCU component consists of:

4 XV3000 MCU User's Guide Page 4 of 23 MCU DSP board (MCU-DSP), which is a PCI Express DSP-farm board, designed to provide powerful and cost-effective multimedia processing capabilities. The board has an Ethernet interface that is used for communication with MCU communication software. MCU communication software (MCU-CS) that provides SIP User gent (U) functionality and communicates with the MCU-DSP via IP protocol. MCU-CS also works as a Real-time Transport Protocol (RTP) relay by forwarding the RTP messages to/from MCU-DSP. Web-based MCU configuration software XV3000 MCU Communication Scheme The MCU-DSP is connected to the IP-PBX eth1 Ethernet interface by straight CT 5e or CT 6 cable. Conference participants can connect to the MCU-CS by using SIP protocol via the eth0 interface of IP-PBX either through sterisk (port 5060) or directly to the MCU-CS (port 5070). The RTP messages will always be transmitted via the eth0 interface and forwarded to/from MCU-DSP by MCU-CS. eth1 eth0

5 XV3000 MCU User's Guide Page 5 of 23 Methods to Call the MCU The IP-PBX users must be able to create SIP calls to the MCU-CS that is running on the same XV3000 and listens for incoming SIP messages on port 5070/udp. When the MCU-CS receives a call then it behaves as described in the table below: Called number ctions Example of SIP request URI n access number (ref. System Settings / ccess Numbers ) meeting room number (ref. Conference Management ) n access number, a meeting room number and PIN separated by the * sign The caller will be prompted for the conference number they want to join, and optionally for a PIN The caller may be prompted to supply a PIN The caller will join the requested conference sip:500@ sip:100@ sip:500*100*1234@ Three methods for configuring the PBX/MCU-CS communication are described below. In all of the examples it is assumed that: the IP address of the IP-PBX (and MCU-CS!) is the MCU-CS access number is 500 there is a conference defined as 100 PBX Users Call the MCU via a SIP Trunk In the PBX configuration it is possible to define a SIP trunk for the MCU-CS and one or more outbound routes for that trunk. a) Create a SIP trunk called ConfBridge b) Create an outbound route for calling to this trunk. Define the route name as 'MCU' and choose the prefix '52' for the route:

6 XV3000 MCU User's Guide Page 6 of 23 The IP-PBX users will have to dial 52 and then any three digits in order to make a call via the ConfBridge SIP trunk. The '52' prefix will be stripped off automatically from the called number. For example, in order to call the MCU access number 500, the IP-PBX users would dial The SIP trunk approach has the following limitation: the callers who access the IP-PBX via the other trunks will not be able to call MCU unless either: a) context=from-internal is defined for those trunks, which significantly decreases the PBX protection level, or b) some special customization for the standard FreePBX dialing plan is implemented. lternatively, it is possible to configure the MCU to register the access number(s) and/or the conference number(s) as regular IP-PBX extensions. In this case the external IP-PBX users will be able to call the conference bridge, just like they would any other IP-PBX extension. PBX Users Call the MCU Just Like Regular IP-PBX SIP Extensions a) Define a SIP IP-PBX extension for each access number and a conference number the MCU should register. b) Enable the corresponding access number and/or conference number registration in the MCU configuration. (Ref. topic ccess Numbers and Conference Management.) Users Call the MCU Directly The MCU-CS listens for SIP messages on port 5070/udp. Therefore, it is possible to call the MCU-CS directly, bypassing the IP-PBX. Most SIP video phones allow this. Following is an example of this method using Linphone:

7 XV3000 MCU User's Guide Page 7 of 23 This method is used to provide the caller with a HD video stream from the conference bridge. Unfortunately, sterisk does not handle HD video SDP parameters in the SIP messages correctly. s a result, the MCU does not get the correct information about the caller capabilities to receive the HD video. The workaround is to call the MCU directly. The direct call method may also be useful when dialing the MCU as access_number*room_number*pin. For example, sip:500*100*1234@ where 500 is the access number 100 is the meeting room number 1234 is the PIN IP Settings The following table describes the required IP settings to be configured depending on the LN parameters: IP Conflict: nnn is already in use on the LN No Yes Required Changes IPPBX eth0, MCU-CS MCU-DSP, IPPBX eth0 and eth1, MCU-CS IP Settings of the MCU-DSP The IP address of the MCU-DSP board is written in its EEPROM. By default, the MCU-DSP address is In order to change the address the board must be connected via the RS-232 interface. Please refer to ppendix : How to change MCU-DSP IP Settings for further details. IP Settings of the IP-PBX The table below contains the default IP settings of IP-PBX: Interface name eth0 Parameters DHCP eth1 IP address: Network mask:

8 XV3000 MCU User's Guide Page 8 of 23 If the nnn addresses are already in use on the LN then it is necessary to change the IP addresses of the MCU-DSP and of the eth1 interface in order to avoid conflict of IP addresses. Please refer to ppendix : How to change MCU-DSP IP Settings for further details. Use either the LCD panel or a keyboard and a display monitor to obtain and/or change the eth0 or/and eth1 IP settings. Please refer to ppendix B: How to obtain/change IP address by using the LCD panel or ppendix C: How to obtain/configure IP address by using a keyboard and a display monitor. Configuring the MCU-CS IP Settings The MCU-CS automatically uses the XV3000 IP settings. If the XV3000 IP addresses and/or the MCU-DSP address have been changed, then it will be necessary to reboot the server in order for the MCU-CS to use the new settings. MCU dministration and Configuration Overview The administration and the configuration of MCU is done through the GUI of the Web-based management system. Login ccess the following URL to reach the MCU management screens: IP address>/mcu The default username/password is admin/admin. Main Menu Once the user has logged in the main menu is displayed. The main menu is divided into two major categories: a) System Setting b) Conferences Select the desired category in the horizontal menu located in the upper section of the screen. Each category has its own vertical menu. Before starting to set up a conference, the system parameters should be configured. The System Settings menu is displayed in the graphic below.

9 XV3000 MCU User's Guide Page 9 of 23 System Settings User Management (SYSTEM SETTINGS / USER MNGEMENT) The MCU user list is managed on this page. It is possible to add or remove users, define their role and change their passwords: dd a new user to the system - Modify the user information - Delete the user from the system - In order to add a new user, the administrator should define a username, a password and select a role for the user. The role can be either admin or user. The admin role permits access to all system capabilities. The user role limits the user to creating a conference and viewing the conference information. This role does not allow the user to configure the system and manipulate (add/edit/delete) the other users. To ensure the system's security, before starting to use the XV3000 MCU it is highly recommended to change the default user name and password.

10 XV3000 MCU User's Guide Page 10 of 23 Network Settings (SYSTEM SETTINGS / NETWORK SETTINGS) Don't change anything on this page! SIP Settings (SYSTEM SETTINGS / SIP CONFIGURTION) In order for the MCU access phone numbers and/or conference name to be registered on a SIP server as SIP endpoints the SIP server parameters must be defined on this page. Define the IP-PBX parameters here, as follows: 'asterisk' in the Domain field the IP-PBX eth0 IP address in the Registrar IP field. If the MCU should be registered on the local XV3000 sterisk server then define as the IP address in the Registrar Port field The Local Listening SIP Port parameter defines the IP ports to which the MCU is listening for incoming SIP messages. If there are any SIP endpoints that are registered on the MCU they can be seen by clicking on the Registration Table button. ccess Numbers (SYSTEM SETTINGS / CCESS NUMBERS) There are two ways to join a conference on the XV3000 MCU: a) create a SIP call to one of the access numbers pre-configured in the MCU. The caller will be prompted to enter a conference number and then, optionally, the PIN number.

11 XV3000 MCU User's Guide Page 11 of 23 b) create a SIP call to a number assigned for particular conference. The caller will be optionally prompted to enter their PIN number. Define a list of access numbers on this page: It is possible to configure the MCU to register a particular ccess Number as a SIP endpoint on the SIP server that is configured on the SIP CONFIGURTION page. NOTE: Video Quality parameter is set for each access number. This parameter defines the maximum video resolution of the video stream to be sent to a participant who has joined a conference by dialing that specific access number. For example, if you set Video Quality as Normal (CIF) for a specific access number and the video conference video quality is defined as HD (720p), then all users who access the video conference via the access number will be limited to CIF resolution.
