Using a gateway with an easymeeting™ client (user mode: supervisor)

Call a H.323 Gateway

Suppose you have created a conference in which:

•      Two users can participate with worldwide easymeeting clients;

•      It has been associated with two gateways with name=”gatewayN” with the parameter “auto answer” on;

•      That the parameter “Accept incoming call without supervisor” has been activated in the section Setup->Connection server.

Once started, the Server performs the following actions:

•      Connect and configure the gateway;

•      Requires the Gatekeeper to authenticate (if necessary);

•      After about thirty seconds, the server creates and activates the conference referred to above;

•      The conference is part of a virtual user with the name of the gateway.

If you connect a client to the server at the conference in question and participate in the conference just created in the Users Window should have four users:

•      two easymeeting™ users

•      two gateway users

By convention the user that represent a gateway is represented by a phone.

 

User Window with Gateway

 

The supervisor, which is a normal easymeeting™ client, can call one of two gateways positioned just above it in the Users Window and right clicking the mouse. You get the usual context menu, with the “Make H323 Call” option.

Context Menu on a Gateway user

With this option, we open one additional window titled “H.323 Call”:

 

Call H.323 device window

In this window you can enter the IP address or alias of the H.323 terminal to call. If we call an H.323 endpoint after a while we will see the image instead of the user's phone, indicating that the connection was successful.

H.323 connection was successful

By placing the mouse on the name of the gateway a hint (or a text message that appears by placing your mouse over the name of the gateway) will show us additional information about connecting H.323.

Obviously, at this point the Supervisor is the user gateway in a way similar to all other users, Enable/Disable Full Duplex on the channel, taking care not to ever enable on Channel 1 of Full Duplex.

 

When the endpoint terminates the connection, the Server Message window shows the message related to the closure of the gateway and the image returns to a phone.

 

If you want, the connection may also be terminated by the client, just select “End Call” from the context menu of the connecting client, similar to the procedure by which you called.

 

In the last case in the Server message window it will appear that the call has been terminated by the local user.

 

The receipt of the easymeeting™ client H.323

If you enter as a Supervisor in a conference entitled to use the H.323 gateway, double click Menu à Window à Mixer H.323 will open the following dialog box

 

Dialog mixer H.323 window

Through this window the Supervisor manages the manner in which the apparatus H.323 receives audio and video from easymeeting™.

It's possible to choose between 3 modes, see the details:

•      Automatic: the H.323 apparatus will receive streaming audio and H.323 video. This means that it will automatically return the active channel that interacts at the moment; at the time A the user is speaking X and the moment B user speaks Y, the H.323 apparatus receives a single seamless web in which we replace X and Y dynamically. For optimum management of this type of configuration, it is important to respect the rules of politeness which provide no overlap in the dialogue between active users and calibrate the microphones on the same level of input and output. One suggestion that may help is to keep the microphone off and turn it back on only to speak.

•      Only channel1: the H.323 apparatus receives streaming video only in Channel 1 among audio from all active full duplex channels. The supervisor will then manage the communication and the succession of operations, shifting users on Channel 1 from time to time to attend the meeting in full even those who participate through the H.323 apparatus.

•      User selected: in this case, the supervisor manages an audio and video stream composed of several channels (maximum 4), exactly as in Figure 13. Once you enable this option, if you click on the 4 square window with the right mouse button, you'll see the following drop down menu:

where you can select which channel to include in each of the 4 containers. It is also possible to leave one or more blank squares, choosing the “No-channel” option.
