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
gateway
. Enter the name and IP address of the IP VCR and complete the page using the MCU's online help for
Gateways and click Add new H.323

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

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.

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

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.

Downloading recordings from the IP VCR
You may download recordings from the IP VCR which can then be:
• transferred to another IP VCR
• played on your PC using any application that supports MPEG video clips, such as QuickTime Viewer
• converted into a MPEG (.mpg file) using the Codian MPEG Converter tool, that is available from
www.codian.com
• converted into a Windows Media Video (.wmv file) using the Codian WM Converter tool, that is available from
www.codian.com
Clips may be downloaded from the IP VCR in one of two formats: MPEG and .codian. Clips downloaded in MPEG format
may be played on a PC as discussed above; either format may be transferred to another IP VCR, though the (bigger)
.codian files will transfer much more quickly.
Note that if you want to create an MPEG file that includes the content channel (or control the size and positioning of
streams within the MPEG), you will need to use the Codian MPEG Converter tool. MPEGs downloaded directly from
the IP VCR will not include the content channel.

Understanding the folder list
The Folder list displays the hierarchy of folders on the IP VCR. Folders are used to group stored recordings together in a
convenient manner. Stored recordings are one of:
• recordings that have been made using the IP VCR
• recordings that have been uploaded to the IP VCR (see Transferring recordings)
• recordings that are stored externally in an Network Files System (NFS) (see Storing recordings externally)
To view the Folder list, go to

Collapse all button causes the display to show the folder hierarchy without recordings listed. Click the 'plus' sign (+)
The
on individual folders, to show the recordings stored in that folder.
Each folder can contain multiple recordings and sub folders. Next to each folder name in the Folder list, the number of
recordings in that folder is displayed. For folders that are linked to external storage locations, the number of externally
stored recordings is also listed and in this case the number of recordings in the folder includes the number of externally
stored recordings (that is, the number of recordings in the folder is the total number of recordings in the folder).
The folder structure is browsable in the Recordings list (go to
Recordings > Recording list), and by an H.323 endpoint
user calling the IP VCR using an auto attendant. Each folder will appear as a separate auto attendant. If you assign auto
attendant IDs to folders, H.323 users will be able to connect directly to that folder.
If you assign Numeric IDs to recordings, the recordings can then be registered with an H.323 gatekeeper and/or a SIP
registrar enabling users to directly dial a recording. Note that externally stored recordings cannot currently be accessed
via a SIP registrar.
You can create up to 50 folders on the IP VCR.
You can create recordings directly into a particular folder, by assigning a folder with a Recording ID and using a
gatekeeper. For more information about recording IDs, refer to
Adding and updating folders.
Moving recordings and folders
To move a recording stored on the IP VCR or a folder:
1. Go to
Recordings > Folders.
2. Drag the recording or folder to the destination folder.
Note that only internally stored recordings can be moved in this way.
Deleting folders
To delete a folder:
1. Go to
Recordings > Folders.
36
2. Click the delete folder link next to the name of the folder that you want to delete.
Note that when you delete a folder, any recordings stored on the IP VCR inside the folder are moved to the top level
folder and are not themselves deleted. (Note that any externally stored recordings inside a folder that you delete will not
be deleted; they will not become associated with any other folder, but will remain in the NFS location.)
Note that when you delete a folder, any sub folders of that folder are moved to the top-level folder and are not
themselves deleted.

Storing recordings externally
About external storage
Any IP VCR folder (including the root) can be configured to link to an external Network File System (NFS) location.
Recordings in a folder configured to link to an NFS location can either physically be stored on the IP VCR or in the NFS
location. The set of recordings associated with that folder will be the combined set of those physically stored on the IP
VCR (and configured to be in that folder), and those in the external location (which is linked to that folder). Recordings
in the specified NFS location will be visible to the IP VCR and will be able to be played and streamed.
For each folder that you link to an NFS location, you can choose to "Export internal recordings" or not (refer to
and updating folders). When "Export internal recordings" is selected for an NFS link for a folder:
• newly-created recordings in that folder will be exported to the NFS location when they are complete
• newly-uploaded recordings in that folder will be exported to the NFS location when the upload is complete
• existing recordings in that folder on the internal disk of the IP VCR will be exported to the NFS location
• recordings physically stored in the NFS location are visible, and can be played, streamed, and recording details
can be edited (renamed, given new PIN etc)
• HD recordings that will be transcoded for streaming will be transcoded before being exported to the NFS
location
Note that there must be sufficient space for new recordings on the IP VCR, because the recording will be made onto the
IP VCR in the first instance, and then exported to the NFS when complete. The
disk space of the IP VCR.
When "Export internal recordings" is
• recordings physically stored in the NFS location are visible, and can be played, streamed, and recording details
can be edited (renamed, given new PIN etc)
Recordings stored externally (and/or automatically exported) are in the .codian file format only. You can copy .codian
files into the external location and they will be "seen" by any IP VCR folder linked to that external location. Multiple IP
VCRs can have access to the same external location (or set of external locations). The recordings stored in the external
location can be played back via the IP VCR in the usual ways, or downloaded to a PC and converted into MPEG or
Windows Media Video formats using the Codian Converters (available on
not selected for an NFS link for a folder:
Status > Recording page displays the free
www.codian.com).
Adding
Consistency of file information across multiple IP VCRs
To ensure that multiple IP VCRs listing a single recording show consistent information, that is PIN, Numeric ID, and
Name, each exported recording consists of two parts:
• a .codian file
• an associated (by filename stem) XML "sidecar" file. This "sidecar" file is not required in order to play back the
recording (whether that play back is an H.323 viewing, web-based streaming, or processing by an application
such as a Codian Converter) but is required so that if the information relating to that recording (that is the PIN,
Numeric ID, or Name) has been changed by one IP VCR then the new information is seen by any other IP VCR
42
H.323 gatekeeper registration of externally stored recordings
Each IP VCR folder that links to an external location has a separate "Register external recordings with gatekeeper"
setting. When this is selected, each external recording retains its own H.323 gatekeeper and SIP registration option. If
"Register external recordings with gatekeeper" is not selected then the recordings in this folder that are stored in the
external location will not be accessible via the gatekeeper (unless this has been configured via another IP VCR). Note that
unless an individual recording is configured to be registered with an H.323 gatekeeper, then no registration of that
recording's Numeric ID will take place (refer to
This enables your configuration of the IP VCR to navigate the issues that will arise if multiple IP VCRs are able to see the
same set of recordings at an external location and if these recordings are registered with a gatekeeper. For example:
• if you have multiple IP VCRs registered with the same gatekeeper, in which case no more than one would be
able to register a recording's configured Numeric ID
• if you have IP VCRs registered with different gatekeepers, in which case it would be valid for them to register
the same set of IDs
• multiple IP VCRs might be registered with the same gatekeeper but using different prefixes; again, the same set
of recordings could be registered by multiple IP VCRs
Note that currently there is no corresponding SIP registrar option for externally stored recordings.
Viewing and updating recording details).
NFS server information
NFS version 3 is supported by the IP VCR . This does not support client-based user / password authentication, instead
requiring server-side access control (typically based on remote address).
The NFS server can be configured as "read-write" or "read-only". If the server is "read-only", the IP VCR will not be
able to modify the XML "sidecar" file of an external recording or export recordings. If the server is "read-write", the IP
VCR can modify the XML "sidecar" file of external recordings and export recordings (if the folder is in "export" mode).

This value represents the maximum amount of
video traffic that the remote endpoint will send to
the IP VCR. It may send less data than this (if it
does not need to use the full channel bit rate or
the IP VCR has requested a lower rate), but it
should not send more.
This value might be less than the Channel bit rate
if:
• the IP VCR detects that the network
path to the remote endpoint has
insufficient capacity to maintain a higher
traffic rate
• that endpoint's video stream's position in
the active conference compositions does
not require it
• it has been necessary to reduce the video
bit rate because of the overall call bit
rate; the audio bit rate plus the video bit
rate should not exceed the call bit rate
50
For example, if all participants in the conference
were watching a single participant at full screen,
no other participants' video streams would be
needed at all. So the IP VCR would request that
those streams were sent at a low bit rate in order
to avoid needless use of network bandwidth.

Displaying the gateway list
You can configure the Codian IP VCR to work with one or more H.323 gateways. The IP VCR can then effectively call
through these configured gateways to one or more endpoints which are registered with the gateway but would not be
reachable directly from the IP VCR.
For example, an IP PBX could be configured as a gateway, and the IP VCR could then call its registered E.164 numbers.

Displaying the built-in gatekeeper registration list
The IP VCR contains a built-in gatekeeper with which devices can register multiple IDs. IDs can be numbers, H.323 IDs
(e.g. Fredsendpoint) or prefixes.
Up to 25 devices can be registered without a feature key. Feature keys can be purchased to increase this number.
Note: The IP VCR can register with its own built-in gatekeeper. The IP VCR then counts as one registered device. See
Configuring gatekeeper settings.
Configuring the built-in gatekeeper
To start the gatekeeper, go to Network > Services and select the H.323 gatekeeper check box to open a port for the
gatekeeper. (On the IP VCR, ports are not open by default for security reasons.) Then go to
in the Status field and click
Apply changes. If you attempt to enable the built-in gatekeeper without opening the port, an
error message is displayed.
Configuring neighboring gatekeepers
You can optionally configure the built-in gatekeeper with up to two neighboring gatekeepers. This means that if the builtin gatekeeper receives a request (known as an Admission Request or ARQ) to resolve an ID to an IP address and that ID is
not currently registered with it then it will forward that request to its neighbor gatekeeper(s), as a Location Request
(LRQ). The built-in gatekeeper will then use the information received from the neighbor(s) to reply to the original
request.
Gatekeeper, select Enabled
You can also configure the behavior of the built-in gatekeeper on receipt of LRQs from another gatekeeper. It can:
• send LRQs regarding unknown IDs to its neighbor(s)
• reply to LRQs from other gatekeepers
• accept LCFs (Locations Confirms) from non-neighboring gatekeepers
Refer to this table for assistance when configuring the built-in gatekeeper:

Gatekeeper status
The number of registered devices is shown in the format X / Y where Y is the number of registered devices that your
built-in gatekeeper is licensed for. Equally, the total number of registered IDs is shown as Z / 1000, where 1000 is the
maximum number of registrations allowed over all registered devices.
Below these summary figures is a table showing individual registrations. Registrations can be viewed by registered ID (the
"ID view") or by device (the "Registration view"), giving complete and easily searchable lists. Switch between the views
by clicking on the appropriate button.
63
The Registration view shows the summary per device (also known as the registrant), while the ID view shows individual
registrations. This means that registrations from the same device are not necessarily listed together in the ID view but the
view can be sorted by Registrant or Index to help you identify IDs belonging to the same registrant.

Configuring IP routes settings
If the Video Firewall feature is enabled (see Upgrading the firmware), you will need to set up one or more routing settings
to control how IP traffic flows in and out of the IP VCR.
It is important that these settings are configured correctly, or you may be unable to make calls to or from the IP VCR or
access the web interface.
To configure the route settings, go to

Viewing and deleting existing IP routes
Configured routes are listed below the Add IP route controls. For each route, the following details are shown:
• The IP address pattern and mask
• Where matching packets will be routed, with the possibilities being:
o Port A - meaning the default gateway configured for Port A
o Port B - meaning the default gateway configured for Port B
o <IP address> - a specific address has been chosen
• Whether the route has been configured automatically as a consequence of other settings, or added by the user as
described above.
The default route is configured automatically in correspondence with the default gateway preference field (see
Port

this route.
Manually configured routes may be deleted by selecting the appropriate checkbox and clicking
Delete selected.
Routes behavior with disabled ports
If the default gateway preference is set to Port B (for example) and that port is disabled, the default route will be updated
automatically to route packets not covered by any manually configured route via Port A.
76
If a manually configured route specifies Port B (for example) and that port is disabled, packets matching that route will
not be automatically routed via Port A, but discarded. You should take care to avoid this situation.

that external users are entitled to, for example, by disabling FTP access via Port B. Refer to the table below for more
details.
In addition to controlling the Ethernet interfaces over which a service operates, this page also allows an administrator to
specify the port number on which that service is provided. If the port number for a service is changed, it is necessary to
ensure that the new value chosen does not clash with the port number used by any of the other services; it is not,

Configuring QoS settings
To configure Quality of Service (QoS) on the IP VCR for audio and video, go to Network > QoS.
QoS is a term that refers to a network's ability to customize the treatment of specific classes of data. For example, QoS
can be used to prioritize audio transmissions and video transmissions over HTTP traffic. These settings affect all audio and
video packets to H.323 and SIP endpoints, and to streaming viewers. All other packets will be sent with a QoS of 0.
The IP VCR allows you to set six bits that can be interpreted by networks as either Type of Service (ToS) or
Differentiated Services (DiffServ).
Note: Do not alter the QoS settings unless you need to do so.
To configure the QoS settings you need to enter a six bit binary value.
Further information about QoS, including values for ToS and DiffServ, can be found in the following RFCs, available on
the Internet Engineering Task Force web site
• RFC 791
• RFC 2474

Do not alter this setting unless you need to.
ToS configuration
ToS configuration represents a tradeoff between the abstract parameters of precedence, delay, throughput, and
reliability.
ToS uses six out of a possible eight bits. The IP VCR allows you to set bits 0 to 5, and will place zeros for bits 6 and 7.
83
• Bits 0-2 set IP precedence (the priority of the packet).
• Bit 3 sets delay: 0 = normal delay, 1 = low delay.
• Bit 4 sets throughput: 0 = normal throughput, 1 = high throughput.
• Bit 5 sets reliability: 0 = normal reliability, 1 = high reliability.
• Bits 6-7 are reserved for future use and cannot be set using the IP VCR interface.
You need to create a balance by assigning priority to audio and video packets whilst not causing undue delay to other
packets on the network. For example, do not set every value to 1.
DiffServ configuration
DiffServ uses six out of a possible eight bits to set a codepoint. (There are 64 possible codepoints.)
The IP VCR allows you to set bits 0 to 5, and will place zeros for bits 6 and 7. The codepoint is
interpreted by DiffServ nodes to determine how the packet is treated.
Default settings
The default settings for QoS are:
• Audio 101110:
o For ToS, this means IP precedence is set to 5 giving relatively high priority. Delay is set to low,
throughput is set to high, and reliability is set to normal.
o For Diff Serv, this means expedited forwarding.
• Video 100010:
o For ToS, this means IP precedence is set to 4 giving quite high priority (but not quite as high as the
audio precedence). Delay is set to normal, throughput is set to high, and reliability is set to normal.
o For DiffServ, this means assured forwarding (codepoint 41).
To return the settings to the default settings, click
Reset to default.

Displaying and resetting system time
The system date and time for the IP VCR can be set manually or using the Network Time Protocol (NTP).

The IP VCR re-synchronizes with the NTP server via NTP every hour.
If there is a firewall between the IP VCR and the NTP server, configure the firewall to allow NTP traffic to UDP port
123.
If the NTP server is local to Port A or Port B then the IP VCR will automatically use the appropriate port to communicate
with the NTP server. If the NTP server is not local, the IP VCR will use the port that is configured as the default gateway
to communicate with the NTP server, unless a specific IP route to the NTP server's network/IP address is specified. To

Configuring encryption settings
You can configure the IP VCR to record encrypted conferences on an MCU and encrypted calls from H.323 endpoints,
and to encrypt the connection when playing back a recording to an H.323 endpoint.
Notes:
• An encrypted recording can be later played back to an endpoint that is not capable of AES encryption, and
conversely a non-encrypted recording can be played back on an encrypted connection at a later date
• SIP encryption is not supported by the IP VCR
The encryption technology that the IP VCR uses is Advanced Encryption Standard (AES).
To use encryption, you must have the Encryption feature key present on the IP VCR. For information about installing
feature keys, refer to
Upgrading the firmware. To access encryption settings, go to Settings > Encryption.

strongly favor a resolution of at least 25
frames per second
• Favor sharpness: the IP VCR will use the
highest resolution that is appropriate for
what is being viewed
• Balanced: the IP VCR will select settings
that balance resolution and frame rate
(where the frame rate will not be less than
12 frames per second)
Choose the unit-wide setting for transmitted video
resolutions. This setting can be overridden by
individual configured endpoint settings.
The settings for motion (frames per second) and
sharpness (frame size or resolution) are negotiated
between the endpoint and the IP VCR. This setting
controls how the IP VCR will negotiate the settings
to be used with an endpoint.
Retain the default setting (Allow all resolutions)
unless you are experiencing problems with the
display of certain resolutions by endpoints.
Endpoints advertise the resolutions that they are
able to display. The IP VCR then chooses from
those advertised resolutions, the resolution that it
will use to transmit video. However, some
endpoints do not display widescreen resolutions
optimally. In these cases, you might want to use
this setting to restrict the resolutions available to
the IP VCR.

Which video codecs the IP VCR advertises to
remote endpoints, restricting the endpoints' choice
of channels available for sending video data to the
IP VCR.
Allows the IP VCR to vary the resolution and codec
of the video being sent to a remote endpoint within
the video channel established to that endpoint. The
options are:
• None: Do not allow video size to be
changed during transmission
• Dynamic resolution only: Allow video size to
be optimized during transmission
• Dynamic codec and resolution: Allow video

and/or dynamic codec selection
When communicating with an endpoint, the IP
VCR receives a list of supported video codecs from
the endpoint. The IP VCR chooses a video codec
from those available, and sends video data to the
endpoint in that format.
With this option enabled, the IP VCR can, for
instance, decide to send CIF video within a 4CIF
channel if this will increase the viewed video
quality.
The circumstances under which decreasing the
video resolution can improve the video quality
include:
• if the original size of the viewed video is
smaller than the outgoing channel
• if the remote endpoint has used flow
control commands to reduce the
bandwidth of the IP VCR video
transmission
Typically, lowering the resolution means that the
IP VCR can transmit video at a higher frame-rate.

448p or w448p video (resolutions of 576
x 448 and 768 x 448 pixels respectively)
to those endpoints that are known to work
89
best with these resolutions.
Video format
Maximum

The video format used and transmitted by the IP
VCR.
• NTSC
The IP VCR will favor transmitting video
at 30 frames per second, at SIF-like
resolutions.
• PAL
The IP VCR will favor transmitting video
at 25 frames per second, at CIF-like
resolutions.
The maximum payload size (in bytes) of the packets
sent by the IP VCR for outgoing video streams
(from the IP VCR to connected video endpoints).
NTSC is typically used in North America, while PAL
is typically used in the UK and Europe. Setting this
field to match the most common type of endpoint
used with the IP VCR will improve the smoothness
of the video sent by the IP VCR to the endpoints.
Regardless of how this setting is configured, the IP
VCR will accept video from endpoints at either
frame-rate.
Typically, you only need to set this value to lower
than the default (1400 bytes) if there was a known
packet size restriction in the path between the IP
VCR and potential connected endpoints.
Video streams generally contain packets of different
lengths. This parameter only sets the maximum size
of a transmitted network datagram. The IP VCR
optimally splits the video stream into packets of
this size or smaller. Thus, most transmitted packets
will not reach this maximum size.

packets which comprise the far end's video stream.
When selected, audio will be delayed to be

You should only enable this option if you are seeing
video interlacing artifacts or on the advice of
Codian technical support. Note that all resolution
restrictions imposed by this setting apply only to
video being sent from endpoints to the IP VCR.
The IP VCR can send these messages to endpoints
requesting that the bandwidth of the video that they
are sending be decreased or increased, up to the
maximum bandwidth of the channel.
The IP VCR can send these messages to endpoints
requesting that the bandwidth of the video that they
are sending be decreased based on the quality of
video received by the IP VCR.
If there is a bandwidth limitation in the path
between the endpoint and the IP VCR, it is better
for the IP VCR to receive every packet of a lower
rate stream than to miss some packets of a higher
rate stream.
A setting used only to rectify some types of 'lip

endpoints. Leave at default setting, unless advised
to alter it by Codian technical support or a reseller.

name as caller
/ called ID
When selected, the recording or folder name is
used for the ID instead of the default device name.
When selected, for calls in to the IP VCR the called
ID will be:
• the recording's name for calls directly to a
recording for play back
• the default device name for calls to the
(unnamed) root folder's auto attendant,
recording ID or recording console ID
• the folder's configured name for calls to a
(named) non-root folder's auto attendant,
recording ID or recording console ID
Note: When an endpoint calls the IP VCR to start a
point-to-point recording, it will see the called ID as
the remote device name rather than the IP VCR.
When selected, for calls from the IP VCR the caller
ID will be:
• the recording's name when calling out to
play back a recording
• the specified recording name when calling
out to make a new recording
• the default device name when calling out
to make a new recording in the root folder
with no recording name specified
• the folder's configured name when calling
out to make a new recording in a non-root
folder with no recording name specified
With this setting unselected, the caller/called ID is
the name of the IP VCR.

Configuring gatekeeper settings
To configure gatekeeper settings, go to Settings > Gatekeeper.
You can configure the IP VCR to use a gatekeeper, which can make it easier for end-users to watch and make recordings
using directory numbers rather than requiring them to know the IP address or host name of the IP VCR.
Note that recording IDs, recording console IDs, and auto attendant IDs are properties of folders (refer to
Understanding
the folders list) and can all be registered with the gatekeeper. To register these IDs with the gatekeeper, check Register
folder IDs
. For more information, refer to the table below.

Field Field description Usage tips
H.323
gatekeeper
usage
Enables the IP VCR to use an H.323 gatekeeper for
registration of numeric IDs of recordings, and for
recording IDs, recording console IDs, and auto
attendant IDs of folders.
When set to Disabled then no gatekeeper
registrations are attempted (and existing
registrations are torn down), regardless of other
gatekeeper or per-recording settings.
When set to Enabled registrations with the
gatekeeper are attempted, and the gatekeeper is
contacted for incoming and outgoing calls. If the
gatekeeper does not respond, calls are still
connected if possible. When set to Required
registrations with the gatekeeper are attempted but
calls are not connected if the gatekeeper cannot be
contacted.
H.323
gatekeeper
address
Identifies the network address of the gatekeeper to
which IP VCR registrations should be made.
This can be specified either as a host name or as an
IP address.
This field will have no effect if H.323 Gatekeeper
usage (see above) is set to Disabled.
The gatekeeper can be either the built-in
gatekeeper enabled on the
Gatekeeper page (see
Displaying the built-in gatekeeper registration list)
or an external gatekeeper. To use the built-in
gatekeeper enter "127.0.0.1". For an external
gatekeeper, enter its host name or IP address.

Before the IP VCR can register any recordings with
the H.323 gatekeeper, it must make a unit-wide
registration.

Prefix for IP
VCR
registrations
Specifies an optional group of digits that can be
used as a prefix in either (or both) of the following
ways:
Recordings registered with a gatekeeper have a
unique number that may be entered from a video
conferencing endpoint to connect directly to the
recording. This eliminates the need for users to
• use as prefix for registrations: the
numbers are added to the beginning of
navigate the auto attendant or to know the IP
address of the IP VCR.
each recording's Numeric ID (or any of a
folder's IDs) before registering it with the
Folders registered with a gatekeeper have:
H.323 gatekeeper (you must have checked
register with H.323 gatekeeper in the
recording's settings). For example, if a
recording has a numeric ID of "2222" and
• an auto attendant ID that may be entered
from an endpoint to connect directly with
the auto attendant of that folder
93
the registration prefix is "99", then the
recording will be registered with the
gatekeeper with a gatekeeper ID of
"992222"
• register as a service prefix: the numbers
are used as a service prefix for the IP VCR
on the gatekeeper. That means that any
number beginning with the prefix will be
directed to the IP VCR. Any numbers
following the prefix will be identified by
the IP VCR as a recording number (or
folder ID). For example, if a recording has
Numeric ID "3333" and the IP VCR has a
service prefix of "99" registered with the
gatekeeper, then a user dialing "993333"
will be directed to that recording
This setting does not affect point-to-point calls for
which prefixes can be set on a per-folder basis (see
Adding and updating folders).
• a recording console ID, that will start up
the recording console
• a recording ID that will cause the IP VCR
to start a recording and place it in the
folder associated with that recording ID
Using registration prefixes:
• To usefully partition the dialing space, you
might need to ensure that all recordings
registered with a gatekeeper from a single
IP VCR start with the same sequence of
digits
Using registration prefixes also can benefit
large-scale dial plan changes. For example,
you can change all IP VCR registrations to
begin with "121" instead of "11" by
changing a single IP VCR configuration
field rather than individually amending
every recording's associated gatekeeper ID
If you want to use folder IDs in
conjunction with a registration prefix,
check the Register folder IDs checkbox
further down the page
Play back
prefix
Specifies an optional extra prefix that the IP VCR
should register with the H.323 gatekeeper
specifically for play back.
Using service prefixes:
• By using a service prefix, the gatekeeper
will automatically forward calls starting
with the service prefix to the IP VCR. The
IP VCR will determine whether the call
matches a valid recording (in which case
the recording will be played back), folder
ID (in which case the call will be recorded
into that folder) or an auto attendant ID
(in which case the auto attendant is
displayed). If no match is found, the
default incoming call action will be
applied (see
Configuring global
connection settings). You do not have to
individually register recordings or folder
IDs with the gatekeeper
These settings will have no effect if H.323 gatekeeper
usage is disabled.

IP VCR gatekeeper registration behavior
This is a summary of the gatekeeper registration behavior on the IP VCR. It also explains how you can use a gatekeeper
for load balancing.
Choice of registered IDs
With the exception of point-to-point prefixes (which are explained below), gatekeeper usage starts with configuring
unique Numeric IDs for individual stored recordings and for folders. For each folder you can configure an Auto attendant ID,
Recording ID and Recording console ID (together called folders IDs in this topic).
After configuring these IDs you can then:
• choose on a per-recording basis whether to register that recording's numeric ID individually with the gatekeeper
using the Numeric ID registration field
• choose on a per-device basis whether to register folders' auto attendant, recording and recording console IDs
individually with the gatekeeper using the Register folder IDs field
• for all recording and folder IDs, choose whether to add a specified prefix to those IDs when registering them
individually with the gatekeeper using the Prefix for IP VCR registrations field with use as prefix for registrations
selected.
• choose not to register recording or folder IDs individually with the gatekeeper but instead make them all
available through one or more registered prefixes using the Prefix for IP VCR registrations field with register as a
service prefix selected and the Play back prefix field. (With a prefix registered, then typically a gatekeeper will send
all calls which start with the prefix to the device which registered the prefix)
You may need to use a prefix if:
• you want more than 100 IDs (recording or folder IDs) to be available through the gatekeeper. (The IP VCR has a
limit of 100 individual dial strings that it is able to register with its configured gatekeeper)
• the number of IDs that you want to be available via the gatekeeper is less than 100 but more than the gatekeeper
that you are using can support
• you want to load balance recording or play back functionality across multiple IP VCRs which register the same
prefix(es). In this case you should configure these IP VCRs so that they deregister those prefixes when all
recording ports are in use. See
You may not be able to use a prefix if: your gatekeeper does not support prefixes - not all gatekeepers offer this
functionality.
Load balancing below.
Matching incoming called numbers
A call can reach the IP VCR with a called ID number when:
• a user dials a number that the IP VCR has specifically registered with the gatekeeper
• a user dials a number that starts with a prefix that the IP VCR has registered with the gatekeeper
• a H.323 call is made directly to the IP VCR as a gateway and a subsidiary number is supplied.
When the IP VCR receives an incoming call involving a called ID, it decides what to do with the incoming call by
following a number of rules in a specific order. If any of these rules provides a decision on what to do with the call, the
process stops at that point and no further rules are tested. The rules in order are:
97
1. If the Prefix for IP VCR registrations has been configured and the called number starts with that prefix, then the IP
VCR tries to match the rest of the called ID number (i.e. the part after the prefix) to a recording's Numeric ID or
to one of the folder IDs.
2. If a Play back prefix has been configured and it matches the called number, then the IP VCR tries to match the rest
of the called number (i.e. the part after the prefix) to a recording's Numeric ID.
3. The IP VCR tries to match the whole of the called number to a recording's Numeric ID or to one of the folder
IDs.
4. The IP VCR tries to match the called number against a folder's configured Point to point call incoming prefix. In the
event that more than one folder's Point to point call incoming prefix matches the called number, the IP VCR
chooses the folder which gives the longest prefix match
5. The call is treated as a call to just the IP VCR's IP address and the configured Default incoming call action is
followed.
Resulting action
If the above sequence results in a match against a recording's Numeric ID, then the recording is played back. If a folder's
Auto attendant ID is matched, then the endpoint is connected to the auto attendant menu for that folder. If the call matches
a folder's Recording ID or Recording console ID, the IP VCR starts a new recording in that folder (and starts up a recording
console, if appropriate).
Which IDs are registered with the gatekeeper
Registering a recording's numeric ID
No individual registration will be made for a recording unless the H.323 gatekeeper checkbox in the Numeric ID registration
field is selected. In addition, if the recording is external (i.e. not stored on the IP VCR's own disk but accessed through a
link to an external NFS server) the folder's Register external recordings with gatekeeper setting must be selected as well as the
recording's own H.323 gatekeeper setting.
If the unit-wide Prefix for IP VCR registrations has not been configured, the IP VCR will register just the recording's Numeric
ID. However, if the Prefix for IP VCR registrations has been configured and use as prefix for registrations is selected, the IP VCR
will prepend that prefix to the recording's Numeric ID before registering it with the gatekeeper.
Registering a folder's auto attendant ID, recording ID, and recording console ID
No folder IDs will be registered with the gatekeeper unless the unit-wide Register folder IDs setting is selected. If it is
selected, then all configured Auto attendant IDs, Recording IDs and Recording console IDs for all folders will be registered with
the gatekeeper.
If the Prefix for IP VCR registrations has been configured and use as prefix for registrations selected for this field, then the IP
VCR will prepend that prefix to all folders IDs before registering them with the gatekeeper.
Registering a folder's point-to-point prefixes
In normal operation, whenever a folder has a configured Point to point call incoming prefix, that prefix will be registered
with the gatekeeper: there is no other unit-wide setting to enable or disable registration unlike the other folder IDs.
However, see
Load balancing below.
98
Load balancing
You can use prefixes to balance the load between a number of IP VCRs by registering them with the same prefixes and
selecting the "deregister" options:
• the Play back prefix will be deregistered if the Deregister play back prefix when all play back ports are in use setting is
selected and all play back ports are in use
• the Point to point call incoming prefix for all folders will be deregistered as will the Prefix for IP VCR registrations (if
register as a service prefix is selected) if Deregister recording prefixes when all recording ports are in use is selected and all
recording ports are in use.
When deregistration occurs, the gatekeeper will chose another IP VCR which is registered with the same prefix when a
call comes in rather than rejecting it.
Configuration rules
One folder's Point to point incoming prefix can be the same as another folder's followed by some more digits; in this case the
IP VCR will use the longest match to determine which folder to create a new point-to-point recording in. For example, if
one folder uses the prefix "123" and another uses "1234", then calls to "12345" and "12346" will use the folder that
registered "1234" and calls to "1235" and "1236" will use the folder associated with the prefix "123".
One folder's Point to point incoming prefix can be the same as a non-prefix ID; for example a recording can be registered as
"1234" in addition to this being a folder's Point to point incoming prefix. In this case a call to "1234" will play back the
recording, and a call to a number that starts with "1234" but has more than 4 digits will trigger a new point-to-point
recording that will be stored in that folder.
A non-prefix ID can be the same as a folder's recording prefix plus some other digits. For example, you can have a
recording registered as "1234" as well as a point to point incoming prefix "123" for a folder - the IP VCR always matches
non-prefix IDs first; therefore a call to "1234" would go to the recording that had specifically registered this ID, whereas
a call to "1235" or "1236" would start a point to point recording.
The following are not allowed:
• 2 identical non-prefix numeric IDs: all recordings' numeric IDs, folders' auto attendant, recording IDs and
recording console IDs must be unique, and all must be different to the unit-wide H.323 ID
• 2 identical prefixes: all folders' Point to point incoming prefix must be unique and must all be different to the unit-
wide Play back prefix and Prefix for IP VCR registrations (if register as a service prefix is selected)
