Introduction
This tutorial provides detailed instructions on how to set up and administer the Codian IP Video Conference
Recorder (IP VCR). It describes how to connect the unit, and then how to log in and use it to set up a
connection with endpoints and conferences.
Using the tutorial
The tutorial is designed to be followed in the order in which the steps are provided.
Online help complements this guide by providing detailed descriptions of each of field. To display
help at any time, click the icon in the top right hand corner of the screen.
In this tutorial the instruction ‘Go to Settings > Gatekeeper’ means click the Settings link on the menu bar
and then click the Gatekeeper tab.
Click on settings
Then click on Gatekeeper
Throughout this guide there are helpful tips in green that explain things in more detail, for example:
Before powering on the IP VCR, connect the blue console cable included with the IP VCR to the
console port.
These provide useful advice on features and functions of the unit.
Assumptions
It is assumed that you have used video conference recording equipment before and understand industry
standard terms.
Ideally you need access to a Codian MCU unit in addition to an IP VCR so you can see the effect of joining
and of recording a conference. To try all of the features described in this tutorial you also need a gatekeeper
and two endpoints.
IP VCR software version
This tutorial was prepared using IP VCR 2200 series version 2.2 software. If you are using this tutorial with a
different release of the IP VCR or the VCR blade (the MSE 8220 VCR blade) some screen shots may be
different.

Connect an Ethernet cable from Ethernet Port A to an Ethernet switch (rather than a hub) in order to
minimize the interference from other devices on the network
The Ethernet port is a 10/100/1000 Mbps auto-sensing connection.
Turn on the IP VCR by plugging in the power lead
The IP VCR does not have an on/off switch.
Assigning an IP Address to the IP VCR
1
Wait until the red alarm light on the front panel is extinguished and the command prompt appears on the
console:
IPVCR:>
By default, the IP VCR 2200 uses DHCP to obtain an IP address. However, you can assign a static IP
address if you prefer or if a DHCP server is not available.
2
Assign the IP address by one of the following methods:
a. To use DHCP, enter dhcpat the VCR prompt and then press Enter.
IPVCR:> dhcp

b. To assign a static IP address, enter the information using the following format and then press Enter:
static <IP> <netmask> <default gateway> <DNS server>
If you do not have a DNS server, use 0.0.0.0 in place of the DNS server address – you must enter a
DNS server address. For example, to assign an address of 192.168.1.2 where the default gateway is at
192.168.1.1, enter:
static 192.168.1.2 255.255.255.0 192.168.1.1 0.0.0.0
3
To display the current IP address, enter status at the VCR prompt and then make a note of the IP address
as you will need it during the tutorial

Choosing a gatekeeper
A gatekeeper is an H.323 entity on the network that provides services such as address translation and network
access control for H.323 terminals, gateways, and MCUs. A gatekeeper is optional on an H.323 network but
its presence allows end users to replay recordings stored on the IP VCR by dialing a number or entering a text
string. H.323 capable devices can be configured to register their IP and alias addresses with a gatekeeper. The
IP VCR can register E.164 numeric IDs with the gatekeeper. H.323 endpoints can then call in to view and
create recordings using numbers instead of having to use an IP address or domain name.
The IP VCR can be configured to work with your existing gatekeeper. If you do not have a gatekeeper on
your network the IP VCR can provide a gatekeeper service for the H.323 network.
Registering the IP VCR with an external gatekeeper
If you already have a gatekeeper on your network follow the steps in this section to configure the IP VCR to
register with it. If you do not have a gatekeeper on your network proceed to Registering the IP VCR with

documentation should describe how to register the endpoint with the gatekeeper.
Registering the IP VCR with the internal gatekeeper
If you do not already have an H.323 gatekeeper on your network the IP VCR can be configured to provide
gatekeeper services. You will also have to configure the firewall on the IP VCR to allow access to the H.323
gatekeeper service. Only complete this section if you have not completed the steps in the Registering the IP
VCR with an external gatekeeper section.
Up to twenty five devices can be registered with the gatekeeper. A feature key can be purchased to increase
this limit.

Creating recordings
There are a number of ways to create a recording:
f Call out and record: the IP VCR, via its web interface, calls out to a H.323 endpoint and records its
media streams
f Make a call to the IP VCR after it has been configured to record incoming calls by default
f Call in to the IP VCR’s auto attendant and select Record session to record yourself
f Call a specific gatekeeper registered numeric ID to trigger a recording
f Call another endpoint through the IP VCR (a point-to-point call) via a prefix the IP VCR has registered
with the gatekeeper. The IP VCR will be part of the call and record the media streams from both
endpoints
Equally there are a number of ways to play back a recording:
f Call out and play: the IP VCR, via its web interface, calls out to a H.323 endpoint and plays back a
recording to it
f Streaming the recording to a user’s desktop via a player application such as QuickTime™
f Calling in to the IP VCR’s auto attendant and selecting the recording for play back
f Registering the recording with a gatekeeper and playing it back by calling its registered numeric ID
In this tutorial you try several ways to record and play back.
Calling out and recording
This section describes how to create your first recording by connecting directly to an endpoint. Later in the
tutorial you will record video from a conference and from a point-to-point call.

Recording point-to-point H.323 calls
In this section you record a point-to-point call that is routed through the IP VCR. A point-to-point call is one
where just two endpoints are involved so you will need two endpoints to work through this section. The IP
VCR must be configured to register a prefix with the H.323 gatekeeper for point-to-point recording to work.
Recording of point-to-point calls is transparent. To start a recording call another endpoint by dialing the
prefix followed by the endpoint number. The recording stops when the call is disconnected.
Before making the first point-to-point call with an H.323 endpoint, check the IP VCR’s Gatekeeper settings.
1
Go to Settings > Gatekeeper
2
Check that the Point to point incoming prefix is set to 71
You are now ready to place a point-to-point H.323 call via the IP VCR. For example endpoint A might have
the IP address 10.2.134.222 and be registered with the gatekeeper with number 5555 and endpoint B could
have an IP address of 10.2.133.203 and number 7777.
When you place the call you dial the IP VCR Point-to-point call incoming prefix before to the number
of the destination endpoint.
Note. Recording SIP point-to-point calls is not currently supported.
3
4
From endpoint A, place a call to 717777
71 is the registered prefix of the IP VCR that you set up previously and 7777 is the number of the
endpoint that you are calling
Answer the call on the receiving endpoint
The IP VCR starts recording both sides of the call once the call has connected.

Go to Recordings
In the list of recordings you see a recording called Recording_<DATE>_<TIME> where the DATE and
TIME are the time that the call was answered. The status column will show Recording.
Hang up the call from one of the endpoints
The IP VCR disconnects the other endpoint for you, stops recording and the stores the recording
automatically.
7
Refresh the Recordings list. The list will show that the recording has stopped
Recording a conference when the IP VCR calls out
You can record a conference being hosted on a Codian MCU by adding the IP VCR to the conference or by
calling the conference from the IP VCR.
Following on from the previous sections, the IP VCR will call out to a conference that has been configured on
the MCU with a conference ID of 123 registered to the gatekeeper. See the MCU tutorial for instructions on
how to do this.
1
Go to Recordings and click Call out and record
2

Using a gateway to call the IP VCR
If you are not using a gatekeeper with the IP VCR and MCU units, each unit needs another method to
identify how to find the other units.
f If you are simply calling a unit you can specify the IP address for that unit in the Host name or IP address
field when you call out
f However, if you want to connect to a specific conference on an MCU or play a recording on an IP VCR
without going via the auto attendant, then you need to set up a gateway on the unit that will call out
first. Each unit can have several gateways defined. Each gateway is not a connection itself but specifies a
connection between two specific destinations, whether local or remote.
As an example of setting up a gateway, in this section you set up a gateway on the IP VCR which is
configured to call the MCU and then use the gateway to add the IP VCR to a conference.

Transferring recordings
You can transfer recordings from an IP VCR to a PC. This is often an intermediate step to transferring
recordings from one IP VCR to another as there is no direct way to do this. You can also transfer a recording
from one IP VCR to another by watching and re-recording; though this takes longer than transferring the
recording file – and may also result in some degradation in quality. You try both these methods in this
section.
Downloading a recording to your PC
In this section you download the “training recording 2” made previously on to your PC.
Recordings are made in a proprietary Codian file format and can be downloaded in this format or as an
MPEG file. When you select to download a recording from the IP VCR as an MPEG file, it will not include the
H.239 content channel. To include the H.239 content channel in an MPEG file, you must download the file to a
PC and use the MPEG Converter – as described later in this section.
Video recordings can be very large: check that you have enough disk space and enough network
bandwidth to download the clip in a reasonable time before following these steps.
Downloading a recording in Codian file format
1
Go to Recordings
2
Click on the name of the “training recording 2” made previously
3
Click download recording to download a file of the recording in Codian format
You would click download MPEG file at this point if you wished to download a file of the recording in
MPEG format.

Select the folder and file name and then click Save
The recording is saved as a file on your PC’s hard disk.
Converting a Codian file to MPEG
You can easily convert a ‘.codian’ file into an encoded MPEG by using the default settings of the MPEG
The installation program is called Codian MPEG Converter.msi. Converting a Codian file to an MPEG
file preserves the H.239 content channel if it was present in the original recording.
To install the MPEG Converter:
1
Download the latest Codian MPEG Tool from codian.com/downloads/software.htm to your PC and
extract the contents of the ZIP file. Double click on the Codian MPEG Converter.msi to install the
software
The Codian MPEG Converter Setup Wizard is displayed.
2
Follow the instructions to install the program. Accept the End-user License Agreement and select a
location in which to install the program

Open an MS-DOS command prompt window and navigate to the directory that you saved the ‘.codian’
recording file in
Type the conversion command in the format: codian_to_mpg <your_filename>.codian
Example: codian_to_mpg recording_0_training_recording_2.codian
This converts the downloaded Codian file to MPEG format e.g. recording_0_training_recording_2.mpg stored
in the same directory. The file contains video encoded to 352 x 288 pixels in size; the video stream is
positioned in the top left corner and the content channel is on the right. If there was a second video stream, it is
shown below the first one.
Consult the Codian Converters Getting Started Guide for more advanced MPEG conversion options such
as setting the video and audio quality and choosing which streams to convert and their positioning.
Uploading a recording from your PC
Any recordings that you have stored on your PC can now be uploaded to another IP VCR or to the same IP
VCR (in which case it must be stored as a different name).
8
Go to Recordings and click Upload Recording
The Uploading Recording page is displayed.
9
Use Browse to select the file to upload from your hard disk
10 Type in a name for recording on this IP VCR to be stored on the IP VCR under. For example if you are
uploading the same recording on to the same IP VCR, use Training Recording 4
11 Click Commence upload
The time taken for the file to be uploaded depends on the file size and your network speed. When the
upload is complete, you see an Upload successfulmessage.
12 Click on the Click here link below the message to see details of the recording that was uploaded
The uploaded recording is stored as Training Recording 4.

Transferring a recording from one IP VCR to another
You can transfer a recording directly from IP VCR to another and you will demonstrate this by copying a
recording from your IP VCR to itself but under another name.
When you are copying from one IP VCR to another, the IP VCR you are recording on needs to know how to
connect to the IP VCR with the original recording on. There are two ways to provide this connection: by
registering both IP VCRs with the same gatekeeper, or by setting up a gateway between the two units. This is
obviously different to the situation in this tutorial when only one IP VCR unit is being used – but the
instructions in this section assume you are using a gatekeeper. (You set up a gateway to an MCU later in this
tutorial – and the same method can be used for a gateway to another IP VCR unit.)
1
Go to Recordings and select Training Recording 4 which you just uploaded
The name of the recording is completed for you.
2
3
Type in a unique numeric identifier for this recording (e.g. 3333)
If you are using a gatekeeper with the IP VCR, select the H323 gatekeeper check box
Registering with a gatekeeper allows users to call from their video endpoint and connect directly to a
playback of this recording. This is one of the simplest ways to allow users to access recordings.
4
If required, specify a security PIN to restrict access to a recording
Recordings can be protected with a PIN. When you try to play a protected recording you see the PIN
entry screen. The PIN must be entered before the recording will play.

Managing endpoints
You can pre-configure endpoints on the IP VCR in the same way as you can on the MCU.
1
Go to Endpoints and click Add H.323
2
Complete the fields using the online help if necessary and then click Add endpoint
Call-out parameters are the values that are used when calling out to an endpoint from the IP VCR. The
Conferencing parameters define the preferred settings for the endpoint.
Similarly Call-in match parameters are details used by the IP VCR when an endpoint that calls in. The IP
VCR tries to match an incoming call to identify the endpoint. Therefore at least one of the Call-in match
parameters fields must be completed and you can complete 1, 2 or 3 of the fields. All the details provided
must match in order to apply the settings to that caller. However, blank fields are ignored.
The advantage of the IP VCR being able to match an incoming call to a pre-defined endpoint is that the
parameters (for instance, the bandwidths) will automatically take effect rather than needing to be set up
each time that endpoint calls in.
Note in the same way SIP end points can be added with the ‘Add SIP’ button in the endpoints screen.
