The Codian MCU web interface is used for administering the MCU device, managing conferences, users, and predefined endpoints. You can also perform many conference-related tasks using the web interface that you cannot
otherwise do.
When connecting to the Codian MCU web interface, you must log in so that the MCU can associate the session with
your configured user and a set of access privileges. The MCU 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 MCU.
2. Click the link on the top right of the screen.
3. To log in as the administrator, click the button and enter your assigned User name and Password.
The main menu appears, restricting the available options based on your access privileges. Administrators have full
access; standard users can create new conferences and manage their profiles; guest users typically can access publicly
available conferences.

Depending on how your system administrator has configured the MCU and conferences on it, you might be able to
join conferences by simply dialing a phone number.
Your system administrator may have configured the MCU to allow you to use your video endpoint to directly dial the
conference by dialing a phone number. You will be required to enter the conference ID, and PIN if required. Or you
may be able to dial by IP address and connect to the auto attendant. See Using an auto attendant for details.
Note that some video endpoints require that you activate the keypad before dialing. For example, you might need to
press the # key.
If your phone system allows calls to the MCU, you may use your regular phone to join conferences as an audio-only
contributor. You must enter the conference ID (and PIN, if required).
If your regular phone number is linked to your video endpoint, then when you use your phone to join a conference,
the video portion of the conference will automatically appear on your video endpoint's screen. You can continue to
use your regular phone for the audio portion of the conference. To do this, the video endpoint must be configured as
that user's associated video endpoint. For more information, refer to Adding and updating users.
The advantages to this method are that you are able to use the same method and phone to make video calls as you do
traditional audio calls. You also may have improved audio signaling. However, this method requires significant
configuration and setup from the system administrator. Your company's network may not have all the components
available to support this method.
When in a conference using an audio-only phone, pressing *6 mutes your phone such that you will not be
contributing audio to the conference; pressing *6 again unmutes you phone.
Audio-only conference participants can show a recording from a Codian IP VCR as their video contribution. To do
this:
1. Either register the MCU and the IP VCR with the gatekeeper or add the IP VCR as an H.323 gateway.
2. Go to > and add the recording as an H.323 endpoint:
i. Set the address as the recording number.
ii. If you are using a gatekeeper, leave the other fields at their default settings; if the IP VCR is set up
as an H.323 gateway, choose the VCR from the H.323 gateway list and leave all other settings as
default.
3. Go to > and set up the user using Adding and updating users for more information and
setting the associated video endpoint as the IP VCR recording.

Your system administrator may have set up an auto attendant for you to use to join conferences. An auto attendant
presents you with a series of menus from which you can choose a conference to join.
For further information about accessing conferences (including the use of DTMF tones), refer to the document
"Accessing Conferences", available in the Documentation area of the web site.
There are typically two ways to call an auto attendant using your video endpoint. Your system administrator should
provide you with information about which method you should use:
Enter the IP address or host name of the MCU device Dial using a standard E.164 phone number
When you successfully connect to the MCU, 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 previous
menu from a sub-menu, 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 join a conference by dialing its numeric ID, followed by a
'#'. If a conference has both a Numeric ID and a Guest numeric ID set, you may enter either ID, and will join the
conference as either a chairperson or guest as appropriate. 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.
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.
8
When in DTMF navigation mode, you will not be able to use the number keys to enter the numeric ID of a
conference.
Typically, you will have these options:
This option enables you to start a new conference that takes place immediately (an "ad hoc" conference). When
creating this conference, you'll need to add a conference ID and optional PIN (to restrict access to the conference).
Other participants are then free to join the conference as they would any other, for example by using the auto
attendant, or by calling in directly (see Calling into conferences).
As the system administrator, you can disable this option so it is not available on an auto attendant.
All permanent conferences or conferences scheduled to take place (at this time) display here, listed by the conference
name. Your system administrator can limit the conferences that display here. So, if you do not see the conference you
want to join, verify the conference name, start time, and finally verify that your system administrator has enabled the
conference here.
Your system administrator may allow this auto attendant to access additional auto attendants, giving you access to
additional conferences.
After you join a conference, the in-conference controls and features are the same regardless of how you joined the
conference (see Using in-conference features).
When you want to leave a conference, you can either simply hang up, or if you joined the conference from an auto
attendant and want to return to the auto attendant:
if you are using FECC, press zoom out. The zoom out menu is displayed; choose if you are using DTMF tones, press 7. The zoom out menu is displayed. Press 8 to navigate down through

After you join a conference, you can control many conference features directly from your video endpoint. (For
information about in-conference features using the web interface, see Controlling in-conference features).

For further information about accessing conferences (including the use of DTMF tones), refer to the document
"Accessing Conferences", available in the Documentation area of the web site.
Your video endpoint typically has navigation keys, such as up/down and left/right (on a keyboard or remote
control), that allow you to control the camera viewing angles. When connected to a conference, you can also use
these controls to scroll through participants and conference layout formats (see Understanding how participants
display in layout views).
When you join a conference, you will have a set of available layout options from which you can choose to display the
conference participants. Typically you can choose from two primary groupings of layouts:
— in these formats, all conference participants display in the same size pane on the video
screen and thus have the same level of focus or importance. For example, a conference with four participants
might display each in a pane sized to be a quarter (1/4) the size of your video screen.
— in these formats, conference participants display in various pane sizes on the video
screen depending on their ―importance‖. For example, a layout might display the participant who is speaking
in a pane larger than the other conference participants. Or, you might choose to focus on a particular
participant (see Selecting participants)
To switch among available conference views:
1. Change the camera control to ―far‖.
2. Use the up/down navigation keys to toggle through the available format options.
3. Refer to the table below for assistance interpreting the icons that appear on-screen.

When viewing a conference with variable-size panes (see Variable-size panes), you can choose which participant to
display in the larger panes on the video screen; when viewing a conference with equal-sized panes, you can choose
which participant displays in the top left pane. You do this by selecting the participant following these steps:
1. Change the camera control to ―far‖.
2. Choose a layout view.
3. Use the left/right navigation keys to scroll through the focused participants.
4. Refer to the table below for assistance interpreting the icons that appear on-screen.

You can configure a welcome message on the MCU and a duration for that message. Participants joining a conference
on the MCU will see the message displayed at the bottom of their endpoint's display. After the configured message
duration has elapsed, the message will be removed.
The controls are on the page (refer to Configuring global
conference settings).
The welcome message will only be displayed to streaming viewers if the duration is configured as permanent.
If you change the welcome message when there are active participants, any participants’ currently displayed welcome
messages will only change if the new message is configured as .

Depending on how your video endpoint is configured, an incoming video call might come through to your regular
phone or to your video endpoint (see Calling into conferences for a brief description of the difference). Note that
even if a video call arrives on your regular phone, the video portion of the call will appear on your associated video
endpoint (if one is configured).
As with any other type of incoming call, you can choose to answer the call or not.
16
The default behavior of the Codian MCU is to display the "loudest" participants in the most prominent layout panes.
If there are more contributors than there are panes available, then the "quietest" participants are not shown.
However, different styles of layout introduce slight subtleties to this behavior, and in addition there are a few ways in
which participants or conference administrators may change the system used for pane assignment. In particular, you
may want to set the pane placement for a conference yourself.
In this section:
Big panes vs. small panesParticipants viewing themselvesChanging view focus"Important" participants"Important" participants combined with view focusClipped panesVideo streams vs. fixed bitmap imagesMuted participantsH.243 floor control
This layout can be seen as the most traditional video-conferencing view. Each participant is displayed in the same
sized pane as the other participants. If there are more than four participants, the four most significant (the four
loudest) are displayed, with one pane each.
By contrast, these example layouts have some larger panes, and the participants shown in those panes are seen as
more significant than the other contributors. When allocating participants to panes, the MCU always fills the largest
panes first. If there are more participants than panes then there will never be empty big panes and non-empty small
panes.
To reduce the number of view changes when different participants speak (for example, when people change from
being active speakers to inactive contributors), the MCU duplicates participant views for layouts with more than four
small panes. For the three example layouts shown above, the participant(s) shown in the large pane(s) of the first two
layouts will be duplicated in the surrounding small panes. However, the four small panes of the third layout will show
different participants to those displayed in the three big panes. This reduces the impact of audio volume changes on
the composed layout while not needlessly wasting view space. However, it is possible to configure the MCU not to
duplicate participant views in this way if so desired (see Configuring global conference settings).
17
When considering which participants to show in which panes, a participant's self view has the lowest priority. This
has two main implications:
When choosing participants to display, the MCU considers the viewer last. This prevents the participant
who is the active speaker from seeing only themselves. In this case, while everyone else will see the active
speaker, the active speaker will see the previous active speaker in their biggest view pane.
When the MCU is required to choose a layout from a view family, it does so based on the number of video
contributors to the conference. However, when calculating the number of video contributors for a
particular view, the MCU does not consider any video stream being received from the viewer.
Thus, with five participants in a conference and everyone seeing the standard equal-sized view family (2x2,
3x3 or 4x4), each of the five contributing participants will always see the 2x2 view with themselves
excluded. However, streaming viewers will see the conference display using the 3x3 view with five panes in
use.
You may configure the MCU never to show participants their own video stream in small panes (see Configuring
global conference settings). If this is the case, then participants viewing layouts with some panes larger than others
will never see their own video stream in any of the small panes, even if there are free slots. They may still appear in
large panes, for example if the view focus is manually changed to show their video.
Using the tilt (up and down) Far End Camera Controls on a connected video endpoint causes the view to change,
cycling through the available families and then the conference-wide or per-participant custom layouts (if enabled).
In addition, the pan (left and right) Far End Camera Controls on a connected video endpoint can be used to focus the
view on a particular participant, as opposed to the MCU allocating participants to panes based solely on the volume of
the audio being received from them.
To reduce the disruption of the view when cycling through conference participants, there is a short delay after
selecting a new focused participant before the rest of the view layout reverts to the "correct" arrangement of
participants in panes.
For each conference, one active participant can be set as "important". This means that the MCU considers this
participant first when deciding which contributors to show in which layout panes, rather than their position in the list
being set by how loudly they are speaking. See the Control setting in the conference participant list.
18
Both "Changing view focus" and "Important participants" above involve a single specific participant being shown in
the biggest pane available, even if that participant is not currently the loudest speaker. This causes a potential conflict,
which is resolved dependant on the type of layout.
In this type of view (a layout in which all panes are of equal size), the focused participant is shown in the first pane,
the one at the top left. The important participant is shown in the "next" pane, normally the one immediately to the
right of the first pane.
This type of layout displays a single big pane and several small panes. If the view focus has been changed (for instance
with left and right Far End Camera Control operations), then the big pane shows the selected participant. If a
conference participant has been set to "important" then its video stream is shown in the big pane.
However, if a participant has been set to "important" and the view is focused on a (different) specific participant, the
focused participant is shown in the big pane, and the "important" participant is shown in one of the small panes.
If the view has been focused on a participant and the same participant is also set as "important" then that participant is
shown in the big pane.
These layouts have two large panes and several smaller ones. If the view focus has been changed (for instance with left
and right Far End Camera Control operations), then the upper or left large pane shows the focused participant. If a
participant has been set to "important" then that video stream appears in the lower or right large pane.
If the same participant is focused and "important", that video stream appears in the upper or left pane.
For these layouts, if the view has been focused on a particular participant, that participant appears in the upper or left
large pane. If a participant has been selected as "important", that participant will be shown in the lower or right large
pane.
In layouts with three large panes, even if the view is focused on a specific participant and another has been set to
"important", one large pane remains. This pane displays the "loudest" remaining participant.
19
The majority of the conference layouts defined by the Codian MCU, for example:
have in common that all of their panes, whether big or small, have the same aspect ratio as the view itself. That is, the
panes' widths and heights are in the same proportion as the width and height of the encompassing view.
By comparison, there are some defined conference layouts, for example:
in which this aspect ratio preservation does not occur. In these cases, the MCU scales the participant video stream
according to the larger dimension of the pane.
For example, in the layout to the left, the size of the top left pane is one half of the view width and two thirds of the
view height. Because two thirds is greater than one half, the MCU scales the participant video stream to two thirds of
its size and thus a small amount of the left and right of the original image will not appear in the final composed layout.
For video conference participants, the image that displays in the layout view pane is either the live video stream (if
viewing from the video endpoint) or a captured video image from the current video stream (if viewing from the web
interface).
However, audio-only participants do not have any associated video to display. Instead, you can assign a fixed image
(in bitmap format) to a specific participant. When the participant joins a conference as an audio-only participant, this
image appears in the layout pane. To enable this feature, the participant must be added as a user to the MCU, have an
associated E.164 telephone, and have a designated image file uploaded. See Adding and updating users.
Participants who have had their audio muted from the web interface do not contribute audio to the conference.
Additionally, muted participants are not considered when the MCU calculates the loudest speakers to display in the
largest panes, even if the participant had previously been in one of those positions.
Note that other participants will not have an indication that a participant has been muted. They simply will no longer
hear that participant speaking.
Participants who have had their video muted from the web interface do not contribute video to the conference. They
will continue to contribute audio as normal, unless it is muted separately.
20
Some H.323 endpoints support a feature known as floor and chair control that is encompassed by the H.243
protocol. This is not currently supported by SIP.
The MCU supports the following H.243 features:
a participant can "take the floor" in a conference. On "taking the floor" their video contribution is sent to all
conference participants as a "1 x 1 view" (full-screen view). If the active floor (temporarily or permanently)
has no video channel established to the MCU then endpoints will see their "normal" continuous presence
view; if there is a video channel from the active floor participant, everyone will see that video, and this will
override any view family or custom layout setting
a participant can "take the chair". On "taking the chair", a participant can:
onominate a "broadcaster"; that is, they can choose which participant's video will be sent to all other
participants in "1 x 1 view" (full-screen view)
o decide to disconnect any other participant(s)
Note that the ability of a participant to "take the chair" is affected by how they joined the
conference. A participant who joined the conference as a guest will not be able to "take the chair".
an endpoint can receive the names of the other endpoints in the same conference. Different endpoints act on
this in different ways.
Whether or not these features are supported in a conference depends on the individual conference settings
() and the global "H.243 floor and chair control setting" (). Refer
to Adding and updating conferences and Global conference settings.
Where a conference supports floor and chair control, or floor control only:
the MCU will advertise the ability to handle H.243 when establishing (and receiving) H.323 connections any H.243-capable endpoint can request the floor, and all endpoints (be they chairperson or guest) will be
granted it as long as no other endpoint in that conference has already done so
Where the conference supports floor and chair control:
any H.243-capable endpoint can request the chair, and any participant who has joined the conference as a
chairperson will be granted it as long as no other endpoint in that conference has already done so
If an active participant in a conference has taken the chair or the floor, it is indicated in the status column of the
page.
If you change the "Floor and chair control" for a conference currently taking place, there will be no immediate effect.
That is, an existing floor or chair participant will not have that status removed.
For ad hoc conferences, you can alter the "Floor and chair control" setting, which is "Allow floor control only" by
default, through that conference's configuration page when it is active.

If the MCU can connect to an H.323 gatekeeper,
each numeric ID (for both chairperson and guest
privileges) for a conference can be registered with
that gatekeeper as a different directory number.
This allows H.323 users to dial directly into a
particular conference (with the correct privileges)
instead of connecting first to the MCU's auto
attendant and navigating the menu system.
Likewise, if the MCU can connect to a SIP
registrar, each conference can be registered with
that registrar using either (or both) Numeric ID
and Guest ID. This allows SIP users to dial
directly into a particular conference (with the
correct privileges) instead of connecting first to
the MCU's auto attendant and navigating the
menu system. Note that for SIP, unlike H.323,
the conferences must be configured on the SIP
registrar before the MCU can register them.
There is a maximum of four registrations for each
conference: H.323 numeric ID, H.323 guest
numeric ID, SIP numeric ID, and SIP guest
numeric ID. To view further details about the

in the Active conferences list.
The conference is not currently running,
but has been previously active and is now
waiting to be re-activated when the time
of its next repetition is reached.
There is no explicit status for "finished" – when a

The information required to add or update a conference is nearly identical. Refer to these topics for details:
Adding a conferenceUpdating a conferenceAdding configured endpointsUsing IDs and PINs
To add a conference:
1. Go to .
2. Complete the fields referring to the table below for the most appropriate settings for the conference.
3. Click to add the conference and return to the Conference List. The recently added
conference appears either in the Active or Scheduled Conferences depending on its scheduled start time.
Ad hoc conferences (if you allow them) are added by users in the auto attendant.
To update an existing conference:
1. Go to .
2. Click a Conference name and then click the tab.
3. Edit the fields referring to the table below for the most appropriate settings for the conference.
4. Click to add the conference and return to the Conference List. The updated conference
appears either in the Active or Scheduled Conferences depending on its scheduled start time.
The following settings can also be updated for ad hoc conferences:
PIN Layout control via FECC/DTMF Streaming Encryption Floor and chair control Mute on join

The name that users will see on auto attendant
screens and on the MCU's web interface.
Conference names must be unique; conferences
cannot share names.
Only scheduled conferences have a configurable
Name; ad hoc conferences do not have one.
Additional information about the conference,
which can assist users joining conferences.
Use the description to provide more detailed
information about the conference than the name
alone conveys.
This is an optional field for scheduled
conferences; ad hoc conferences cannot be given
a description.
The unique identifier used for dialing in to the
conference (as a chairperson participant) using an
auto attendant or through an H.323 gatekeeper or
SIP registrar. This number can also be used to
stream the conference from the Streaming-only
interface. For more information about
chairpersons and guests, refer to Using IDs and
PINs.
When connected to an auto attendant,
participants can join a conference by typing its
numeric identifier.
If you plan to allow audio-only participants, then
you will need to enter either a Numeric ID or a
Guest numeric ID.
If H.323 gatekeeper registration is enabled for a
conference, the MCU attempts to register the
conference with an E.164 telephone number,
which is comprised of the Registration prefix and
the numeric identifier.
If SIP registration is enabled for a conference,
then the Numeric ID is registered with the SIP
registrar.
Conferences that are simultaneously active must
not share a Numeric ID. For example, a conference
on a Tuesday and a conference on a Thursday can
share a Numeric ID, whereas two permanent
conferences cannot share a Numeric ID. The same
number can be used for the Guest numeric ID, if
there are two different PINs. Additionally,
because the numeric identifier is used in
gatekeeper registration, conferences and auto
attendants cannot share a numeric identifier
value.
For more information, refer to Using IDs and
PINs.
For ad hoc conferences created via the auto
attendant, the number allocated by the
conference creator becomes the Numeric ID. If ad
hoc conferences are registered with the
gatekeeper (and for this to work, the Register ad hoc conferences with gatekeeper control must be
27
enabled on the page),
participants can dial in using this number. Note
that the actual number that participants will dial
depends on whether prefixes are used in the
page.
For an active ad hoc conference, you cannot
configure the Numeric ID.
Provides a level of security to conference access.
If a conference has a PIN set, users cannot join
the conference or change its configuration
without entering the correct PIN. Depending on
the conference settings, it may be possible for
participants to join a conference as a chairperson
(using the Numeric ID and PIN), or as a guest
(using the Guest numeric ID and Guest PIN).
For an ad hoc conference, you can configure a
PIN while the conference is running.
The unique identifier used for dialing in to the
conference (as a guest participant) using an auto
attendant or through an H.323 gatekeeper or SIP
registrar. This number can also be used to stream
the conference from the Streaming-only interface.
For more information about chairpersons and
guests, refer to Using IDs and PINs.
When connected to an auto attendant,
participants can join a conference by typing its
Guest numeric ID.
If you plan to allow audio-only participants, then
you will need to enter either a Numeric ID or a
Guest numeric ID.
If H.323 gatekeeper registration is enabled for a
conference, and you have entered a Guest
numeric ID, the MCU attempts to register the
conference with an E.164 telephone number,
which is comprised of the Registration prefix and
the Guest numeric ID.
If SIP registration is enabled for a conference, and
you have entered a Guest numeric ID, then the
Guest numeric ID is registered with the SIP
registrar.
Conferences that are simultaneously active must
not share a Numeric ID. For example, a conference
on a Tuesday and a conference on a Thursday can
share a Numeric ID, whereas two permanent
conferences cannot share a Numeric ID. The same
number can be used for the Guest numeric ID, if
there are two different PINs. Additionally,
because the numeric identifier is used in
gatekeeper registration, conferences and auto
attendants cannot share a numeric identifier
value.
For more information, refer to Using IDs and
PINs.
Ad hoc conferences cannot be configured with
Guest numeric IDs or PINs.
