Product Description
The XV0500 Video MCU is a multi-point video conferencing system. Its Web-based management system
provides users with a real-time tool for easy system configuration, conference creation, monitoring and
conference control.
The XV0500 Video 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: Advanced 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, VGA, 4CIF and HD(720p)
•Leader-based Conferences: A conference may be managed by a leader, or defined as an un-managed ad-
hoc 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 XV0500 Video MCU allows pre-defined VIP participants to join a conference
without requiring PIN code authentication.
•Registration on a SIP Server: As an optional feature, the XV0500 Video 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 XV0500 Video 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 video/audio MCU component consists of:
•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 Agent (UA) 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

XV0500 Video MCU Communication Scheme
The MCU-DSP is connected to the host mother system eth1 Ethernet interface by straight CAT 5e or CAT 6
cable. Conference participants communicate with XV0500 by using SIP protocol via the eth0 interface port
5060.
Methods to Call the MCU
It is possible to make SIP calls to XV0500 directly or via another SIP server (e.g. IP-PBX).
When the MCU-CS receives a call then it behaves as described in the table below:
Called number
Actions
Example of SIP request URI
An access number (ref.
“System Settings”/”Access
Numbers”)
The caller will be prompted for the
conference number they want to join,
and optionally for a PIN
sip:500@ 192.168.0.61
A meeting room number (ref.
“Conference Management”)
The caller may be prompted to supply
a PIN
sip:100@ 192.168.0.61
An access number, a meeting
room number and PIN
separated by the * sign
The caller will join the requested
conference
sip:500*100*1234@ 192.168.0.61
eth0
eth1

Three methods for configuring the IP-PBX and XV0500 communication are described below. In all of the
examples it is assumed that:
•the IP address of the XV0500 is 192.168.0.61
•the IP address of the IP-PBX is 192.168.0.60
•the MCU-CS access number is 500
•there is a conference defined as 100
PBX Users Call the XV0500 via a SIP Trunk
In the PBX configuration it is possible to define a SIP trunk for the XV0500 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:

XV0500 Video MCU User's Guide Page 7 of 30
Xorcom Ltd. ●P.O. Box 60, Misgav Industrial Park 20174 ●Tel: [phone] ●www.xorcom.com
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 52500.
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.
Alternatively, it is possible to configure the XV0500 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 XV0500 should
register.
b) Enable the corresponding access number and/or conference number registration in the XV0500
configuration. (Ref. topic “Access Numbers” and “Conference Management”.)
Users Call the XV0500 Video MCU Directly
The MCU-CS has its own built-in registrar/proxy SIP server that is by default bound to port 5060/udp.
Optionally it is possible to make inbound SIP calls to the MCU-CS without authentication. This service is by
default bound to port 5095/udp. Those two services allow calling the MCU-CS directly, bypassing the IP-PBX.
Following is an example of an unauthenticated call using Linphone:

If your PBX is Asterisk®-based then one of two direct calling methods is only way to provide the caller with a
HD video stream from the conference bridge. Unfortunately, Asterisk does not handle HD video SDP
parameters in the SIP messages correctly. As 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@192.168.0.61
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 LAN parameters:
IP Conflict: 172.16.200.nnn is already in use on the LAN
Required Changes
No
XV0500 eth0
Yes
MCU-DSP, XV0500 eth0 and eth1
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
172.16.200.2. In order to change the address the board must be connected via the RS-232 interface. Please
refer to Appendix A: How to change MCU-DSP IP Settings for further details.
IP Settings of the XV0500
The table below contains the default IP settings of XV0500:
Interface name
Parameters
eth0
DHCP
eth1
IP address: 172.16.200.1
Network mask: 255.255.255.0

If the 172.16.200.nnn addresses are already in use on the LAN 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 Appendix
A: How to change MCU-DSP IP Settings for further details.
The MCU IP settings can be changed via the Web-based management interface. Please refer to the Network
Settings section below.
If the MCU IP address is unknown and it is not possible to connect to the device’s Web-based management
interface then a keyboard and a display monitor can be used to obtain and/or change the eth0 or/and eth1 IP
settings. Refer to Appendix 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 XV0500 IP settings. If the XV0500 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 Administration and Configuration

(SYSTEM SETTINGS / USER MANAGEMENT)
The MCU user list is managed on this page. It is possible to add or remove users, define their role and change
their passwords:
•Add 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.
