Logging into the web interface
The Codian IP VCR web interface is used for administering the IP VCR device, managing recordings, users, and predefined endpoints. You can also perform many recording-related tasks using the web interface that you cannot otherwise
do.
When connecting to the Codian IP VCR web interface, you must log in so that the IP VCR can associate the session with
your configured user and a set of access privileges. The IP VCR has a set of configured users, and each user has an ID and
password that are used for logging in.
1. Using a web browser, enter the host name or IP address of the IP VCR.
2. Click on the

Watching a recording from the IP VCR
The IP VCR offers a variety of ways to watch stored recordings. These include watching recordings using an H.323
endpoint and watching recordings by web streaming. Watching recordings can be an interactive experience. The
following pages provide detailed explanations of the options available. Refer to these for more information.
• Using a video endpoint to watch recordings
• Using an auto attendant
• Using streaming to view recordings
8
Using a video endpoint to watch recordings
You may watch recordings stored on the IP VCR using an H.323 or SIP video endpoint. There are a number of ways to
connect to the IP VCR; refer to the sections below for details of the options available to you:
• Connecting directly using a phone number
• Connecting via the auto attendant
• Being called by the IP VCR
Note that in the current release, HD recordings cannot be played back by an endpoint.
Watching recordings is an interactive experience. Playback may be paused, rewound and so on. Refer to the section
below for an explanation of the playback controls available:
• Using playback controls from a video endpoint
Connecting directly using a phone number
Your system administrator may have configured the IP VCR to allow you to use your video endpoint to watch a recording
by dialing a particular phone number. Each recording will have a different number to call. Consult your system
administrator for details.
If the recording is protected, you will be required to enter a PIN before you can start playback (see
Entering a PIN ).
Connecting via the auto attendant
The IP VCR features a sophisticated auto attendant menu system that allows you to see a list of which recordings are
available, and select the one you wish to watch with the aid of video previews for unprotected recordings. Refer to
an auto attendant for full details on how to navigate the menu.
If you choose to watch a protected recording, you will be prompted to enter a PIN before you can start playback (see
Entering a PIN ).
Depending on how your system administrator has configured the IP VCR, you may be able to connect to the auto
attendant by dialing a phone number, or by dialing the IP address of the IP VCR. Consult your system administrator for
which options are available to you.
Using
Being called by the IP VCR
As an alternative to calling the IP VCR from your video endpoint, you may instead use the web interface to initiate a call
from the IP VCR to your endpoint. Refer to the section
Once connected, the playback experience is identical to if you had called the IP VCR using one of the methods described
above. Similarly, you may be asked to enter a PIN before playback of protected recordings will start.
Calling out from the IP VCR for details.
9
Entering a PIN
If you connect to a protected recording, you will be presented with the PIN entry screen, and will hear audio prompts
playing.
Use your endpoint's numeric keypad to enter the PIN, followed by #. (Note that some endpoints require you to activate
the keypad before dialing, for example by pressing the # key.)
Using playback controls from a video endpoint
It is possible to control the playback directly from your video endpoint while watching a stored recording using the FarEnd Camera Controls (FECC). Refer to the sections below for details of the controls available, and for the meanings of
on-screen status icons that may be displayed.

11
Using an auto attendant
Your system administrator may have set up an auto attendant for you to use to view stored recordings. An auto attendant
presents you with a menu from which you can choose a recording to watch.
For further information about watching and creating recordings, refer to the document "Watching Recordings", available
in the Documentation area of the web site.
Calling an auto attendant
There are typically two ways to call an auto attendant using your video endpoint. Depending on how the IP VCR is
configured, neither, one or both of these will be available to you. Your system administrator should provide you with
information about which method you should use:
• Enter the IP address or host name of the IP VCR device
• Dial using a standard E.164 phone number
Accessing the main menu
When you successfully connect to the IP VCR, the main menu displays on your video screen, and you should also hear the
audio instructions.
Navigate the auto attendant using the Far-End Camera Controls (FECC) on your video endpoint. Use the up and down
controls to highlight the option or item you require; use right to make your selection. To return to a parent folder from a
sub-folder, use left.
You can jump to the end of the menu when at the start by using the up control; similarly, you will loop back to the start if
you are at the end and use the down control. Note that there is a scroll bar in the bottom right of the video display to
indicate where you are in the auto attendant menu. From anywhere in the menu, you can jump to the first entry with #2
and to the last entry with #8.
By default, the number keys on your endpoint are used to play back a recording by entering its configured numeric ID,
followed by a '#'. If the recording has a configured security PIN, you will be prompted to enter that PIN before the play
back will start. As you start to enter a numeric ID, the sequence you have typed will be shown at the base of the auto
attendant screen. You may cancel the numeric ID entry (for instance to correct an error) by pressing '*'.
If you have connected to the auto attendant using an endpoint that has no FECC capability (for example many SIP
endpoints), you can use the number keys on your endpoint to navigate the menus; this is called "DTMF navigation
mode". DTMF navigation mode enables you to use the number keys: 2, 4, 6, and 8 in the place of up, left, right, and
down respectively.
To enter DTMF navigation mode:
• on connecting to the auto attendant, press the pound (hash) key twice as follows:
##
The message "DTMF menu navigation enabled" appears briefly at the bottom of the auto attendant display.
12
To exit DTMF navigation mode:
• press the pound (hash) key twice as follows:
##
The message "DTMF menu navigation disabled" appears briefly at the bottom of the auto attendant display.
When in DTMF navigation mode, you will not be able to use the number keys to enter the numeric ID of a recording.
Typically, you will have these options:
Record this session
This option enables you to record the video your endpoint is sending to the IP VCR. You will be presented with the
recording console (see
Using the recording console). From here you will be able to monitor your video before and during
recording.
Replay a recording
All recordings stored on the IP VCR in the current folder display here, listed in the order of most recently made first.
The default auto attendant corresponds to the top-level (root) folder.
Unless a recording is PIN-protected, highlighting a recording will show a small preview.
If you select a protected recording, you will be presented with the PIN entry screen, and will hear audio prompts playing.
Use your endpoint's numeric keypad to enter the PIN, followed by #. (Note that some endpoints require you to activate
the keypad before dialing, for example by pressing the # key.)
Access other folders
If the IP VCR has been configured with a hierarchy of folders, you can access child folders of the current location, giving
you access to the recordings in those folders.
When you have finished watching a recording or making a new recording, simply hang up. If you need to make or watch
another recording, you will need to make a new call to the auto attendant.
13
Using streaming to view recordings
The Codian IP VCR supports streaming, which involves sending recorded media (audio and video) to a remote computer,
allowing the user to watch and listen to the recording.
To view a recording using streaming:
1. Go to
2. Click
Recordings.

Using the IP VCR to make a recording
The IP VCR allows you to create recordings in a number of different ways. These include recording conferences on the
MCU, recording single video endpoints non-interactively and via the recording console, and transparent recording of
point-to-point calls with another endpoint. The following pages provide detailed explanations of the options available.
Refer to these for more information.
• Automatically recording a conference on a Codian MCU
• Non-interactive recording of an endpoint
• Using the recording console
• Recording point-to-point calls
In addition to creating recordings using the IP VCR, it is possible to upload existing recordings. Refer to
recordings for more information.

Automatically recording a conference on a Codian MCU
There are a number of different ways in which you can configure your IP VCR and MCU to record conferences that take
place on the MCU. The following are described here:
• Configuring the MCU to call the IP address of the IP VCR
• Using gatekeeper IDs to record conferences directly into folders on the IP VCR
• Configuring the IP VCR as a gateway on the MCU to record conferences directly into folders on the IP VCR
Configuring the MCU to call the IP address of the IP VCR
When you add a new conference, you can add the IP address of the IP VCR as one of the participants. If you have set the
default incoming call action of the IP VCR to be Record session, then when the conference begins, the IP VCR will record
the conference. Recordings made using this method will always be made into the root folder of the IP VCR.
1. On the IP VCR, go to
2. On the MCU, go to
Settings > Connections and for Default incoming call action select Record session.
Conferences and click Add new conference. For information about conference
configuration, refer to the MCU's online help.
3. From the
Conference list, select the conference you have created and click Add participant. In the Address field,
type the IP address of the IP VCR and complete the page using the MCU's online help for more information.
Note that Codian recommends that you configure the call to the IP VCR to use the H.323 protocol and not SIP
(because SIP calls do not support the content channel or encryption).
When the conference starts, the IP VCR will start recording into its root folder. Note that the name of the conference
will be the name of the MCU and will also include the date and time if the
option is checked on the
Settings > Recordings page.
Use date and time in new recording names
Using gatekeeper IDs to record conferences directly into folders on the IP VCR
By using a gatekeeper and gatekeeper IDs, you can automatically record conferences directly into the folders of your
choice on the IP VCR.
1. Set up a gatekeeper: go to
Configuring gatekeeper settings. To use the method described in this procedure, ensure that you select Register
folder IDs
.
2. For each folder into which you want to directly record, ensure you have set a
register these IDs with the gatekeeper.
3. On the MCU, go to
configuration, refer to the MCU's online help.
4. From the
Conference list, select the conference you have created and click Add participant. In the Address field,
type the recording ID of the folder into which you want to record the conference and complete the page using
the MCU's online help for more information. Note that you might want to set
video status
to Muted. Enable Automatic disconnection; this ensures that the IP VCR stops recording when the
conference ends.
Settings > Gatekeeper. For more information about using a gatekeeper, refer to

Initial video status and Initial
When the conference starts, the IP VCR will start recording the session into the folder with the recording ID that you
used in step 4.
16
Note that if you are intending to use this method frequently with the same folder, it will be quicker to configure the
recording ID as an endpoint on the MCU. The procedure is the same as when you configure an H.323 endpoint on the
MCU. For more information, on the MCU, go to
Endpoints > Add H.323 endpoint and view the online help.
Configuring the IP VCR as a gateway on the MCU
By configuring the IP VCR as a gateway on the MCU in conjunction with using recording IDs on the IP VCR, you can
automatically record conferences directly into the folders of your choice on the IP VCR without the need for a
gatekeeper.
1. Configure the IP VCR as a gateway on the MCU: on the MCU, go to

Non-interactive recording of an endpoint
Depending on the configuration of the IP VCR, you may be able to make recordings non-interactively. That is, once
connected to the IP VCR, recording takes place automatically, and with no feedback to the user. If you would prefer to
have more feedback when making recordings, consider using the recording console (see
Otherwise, refer to the sections below for further information on making non-interactive recordings:
• Understanding non-interactive recordings
• Connecting in order to make a recording
• Controlling the recording
Understanding non-interactive recordings
Non-interactive recording gives no feedback as to the status of recording. The IP VCR will not send video to your
endpoint, typically causing your endpoint to display a blank screen. You will not be able to monitor how the recording
will look.
When the call to or from the IP VCR is connected, recording will typically start immediately. However, the IP VCR may
have been configured to delay recording until coherent video is seen. Your system administrator may have configured the
IP VCR in this way to ensure the best quality of recordings.
If you are unsure of whether the IP VCR will start recording immediately or not, wait a few seconds before starting to
speak; this will ensure the best quality recording in all circumstances.

Calling the IP VCR from a video endpoint
To make a non-interactive recording by calling the IP VCR using your video endpoint, follow these steps:
1. Confirm with your system administrator that the Default incoming call action of the IP VCR is to answer incoming
calls by recording them immediately (non-interactively) (see

Controlling the recording
The nature of non-interactive recording is that the user has little or no control over recording. When you have finished
recording, simply hang up the call to end and store the recording.

Using the recording console
The recording console allows you to make recordings interactively. That is, it allows you to monitor the recording while
it is in progress, to check that the view is as you require.

Calling in via the auto attendant
To access the recording console by calling the IP VCR via the auto attendant, follow these steps:
1. Confirm with your system administrator that you may call the auto attendant of the IP VCR, either by using the
IP address of the IP VCR or by dialing a phone number.
2. Connect to the auto attendant using the method chosen in the previous step.

Understanding the recording console display
The recording console display is intentionally simple. Refer to the table below for a description of the different parts of
the display:
Control Control Description
Preview window
In the center of the screen, a window shows a live preview of the video being sent by the
endpoint to the IP VCR. Use this preview to ensure the recorded view is composed as you
require before starting to record. You may also monitor this view whilst recording.
Note that although the audio portion of the call will also be recorded, this is not sent back to the
endpoint like the video preview, as this would cause undesirable feedback effects.
20
Status
A status indication is displayed in the bottom left-hand corner of the recording console. It shows
the current state of recording. When you first enter the recording console, the status indication
will show paused.
Recording length
The length of the recording is shown in the bottom right-hand corner of the screen, as minutes
and seconds. When you first enter the recording console, this will show a zero-length recording.
The recording length will update in real-time as recording progresses. Use this as a guide to how
long your recording will be.
Recording indicator
The recording indicator is shown only whilst recording is in progress, and hence will not be
visible when you first enter the recording console. When you start recording, this indicator will
blink near the top right-hand corner of the screen.
Controlling the recording console
When you first enter the recording console, you will hear audio instructions on which controls you may use. Recording
will not start until you are ready. Refer to the table below for details:
Control Control description Usage tips
Up
Down
Starts recording. The status line will change from
paused to resuming... then to recording.
Stops recording. The status line will change from

When you start recording, the IP VCR waits for a
suitable moment before actually starting to record.
This is to ensure the best possible quality video is
recorded. During this time the status line shows
resuming.... Be sure to wait until the status line says
recording before starting to speak.
When you have finished recording, you will not be
disconnected from the IP VCR unless you hang up
the call.
Note that even when you have finished recording,
IP VCR resources are still in use until the call is
ended, possibly preventing other users from
making recordings in the meantime.
You do not have to explicitly stop recording. If you wish, you may simply hang up the call when you have finished.
Whether you press stop or simply hang up, the recording will be automatically stored by the IP VCR.
21
Recording point-to-point calls
The IP VCR is able to transparently record point-to-point calls. A point-to-point call is one where just two endpoints are
involved - the traditional type of call. If you wish to record point-to-point calls, the gatekeeper settings of the IP VCR
must be configured correctly (see
Instead of simply calling the other endpoint by dialing its E.164 number from your video endpoint, you must add a prefix
that tells the H.323 gatekeeper to pass the call to the IP VCR rather than directly to the other endpoint. Your system
administrator will be able to advise you which prefix to use. The IP VCR will then attempt to call the other endpoint on
your behalf, transparently passing media as normal when the call is connected. With the exception of needing to dial a
slightly different number, the experience of calling the other endpoint should be identical to as if you had called it
directly.
While the point-to-point call is in progress, the IP VCR records both sides of the call using one of the configured layouts
(see
Configuring recording settings). The options include showing both endpoint views side-by-side, and showing the
loudest speaker in a full-screen view with the other shown picture-in-picture.
To make a point-to-point recording, follow these steps:
1. Call the remote endpoint using its E.164 number, including the prefix to pass the call through the IP VCR.
2. Recording will start immediately or shortly after the call is connected, depending on how the IP VCR is
configured.
3. When you have completed your call, simply hang up. The IP VCR will disconnect the other endpoint for you,
and the recording will be stored automatically.

Recording of point-to-point calls is transparent. The calling or called endpoint cannot start or stop recording other than
by hanging up the call.

Calling out from the IP VCR
As well as using your video endpoint to call into the IP VCR in order to make and watch recordings, you may also
perform both of these functions using the IP VCR to call out to your endpoint. The sections below explain how to call out
from the IP VCR to make and watch recordings:
• Calling out to watch a recording

H.239 (content channel video) support
The H.239 protocol allows the Codian IP VCR to support an additional video stream to or from each connected H.323
endpoint. Thus, there are potentially 3 media streams between each H.323 endpoint and the IP VCR: audio, main video
and H.239 video. In general, the main video channel is used for motion video (i.e. high frame rate streams) and the
content channel for less dynamic video such as an accompanying presentation - this is typically a high resolution, low
frame rate video stream.
Support for H.239 video on the IP VCR encompasses:
• Recording H.239 video streams from H.323 endpoints, in either single-endpoint or point to point recordings
• Playing back recorded content channel data to H.323 endpoints via H.239
• Streaming the content channel to users' desktop machines
Recording H.239
When a H.323 endpoint is being recorded, that endpoint may open a H.239 content channel video stream, in addition to
its main video channel. The IP VCR records both video channels, and both are available when that recording is played
back.
When using the
In a point to point recording, the nature of H.239 means that only one of the recorded endpoints is able to supply the
H.239 channel at any one time. Specifically, this means that if one endpoint is supplying the content channel stream then
it must stop transmitting H.239 video before the other endpoint can start. This is in contrast to the main video channel,
which both endpoints are able to transmit and receive simultaneously without restriction.
Recording console, the presence of H.239 video is indicated by a "H.239" icon on the right of the screen.
Playing back content channel video
If a recording includes a content channel video stream, that content channel stream (originally supplied by a H.323
endpoint via the H.239 protocol) can be played back to either other H.323 endpoints or to users viewing a recording via
streaming.
Playing back to H.323 endpoints
Stored content channel video can only be played back to a H.323 endpoint if that H.323 endpoint is capable of receiving a
H.239 video stream in addition to its main video channel. When playing back a recording which includes content channel
video, a H.323 endpoint with no H.239 receive capability will see just the main video channel.
Streaming content channel video
Recorded content channel streams can be played back to users' desktops via web browser-based streaming in addition to
the recorded main video and audio streams. When streaming, users have the choice of playing back just the audio and
main video streams, just the recorded H.239, or both together.
The play back of content channel video is accomplished through use of a Java applet, and therefore Java must be installed
on any machine wishing to view the recorded H.239 video.
