Mac OS

Launching the client

Once registered, log in and download the client from the Downloads section.


The installer package for MAC OS contains the Meetecho client core (which is all you need to run the client) and a MAC style .app file. Meetecho will be installed in your home folder and the app file will be copied in to your Applications directory. The app file is just needed to provide you with a quick shortcut to the Meetecho application. Installing the app file requires administration privileges so you can choose not to install the app package during the installation process. In this case you can launch the client by accessing the Meetecho folder and double clicking the Meetecho app. If you want you can drag the Meetecho icon on your dock bar.

Please beware that, in order to make all client’s features available, you need to have at least Java 1.6 installed. 

Before proceeding with the tutorial, check the Troubleshooting section at the end of this page for a few prerequisites to make sure the application works fine, in order to avoid potential issues later on.


Logging in

Once the client has been launched you will be asked for your credentials.

You have to use credentials and server name provided by the Meetecho Server Administrator.


Configuring the settings

You can set your preferences pressing the setting button on the right hand side


The list of conferences

After the login phase you will be presented with the list of virtual rooms hosted by the server.


A tool tip will show you the tools available in every room


Information details:

  • ConferenceId: the unique identifier of a room;
  • Subject:room’s subject;
  • Status:
    • Registered:the room is empty;
    • Active:at least one participant is in the room.
  • Access:if “Private” you will need a PIN to access the room;
  • Media:
    • Audio:  VoIP or PSTN access;
    • Video:video mixing facility;
    • JSummit:whiteboard and polling ;
    • Slide Presentation: each user can upload a document to show to the other participants (supported formats: Microsoft Office, Open Office or PDF);
    • Remote Desktop: each user can choose to show his desktop and grant remote control to other participants.


Joining a conference

In order to access a room you just need to double click the corresponding ConferenceID.

Audio/Video Moderation and Media Control

Once accessed the room a participant can use all the media available but it will not be able to transmit its audio and video flows.

To be un-muted and transmit your video you can use the “Audio Request” and “Video Request” buttons on the right hand panel.


Taskbar and Shortcuts

The upper tools bar provide users with two different kind of tools

Using these buttons you can select one of the multiple windows opened in your client (corresponding to different available tools). The same buttons are used to notify important events happened in a window.     

The right side of the bar let you use the following features


  • Invite: to invite users to this room
  • Presentation: to upload a document for presentation
  • Send File: to send a file to the other participants
  • Polling: to create a poll
  • Share: to share your desktop
  • Viewer: to open a remote desktop viewer
  • Exit: to leave the room




First of all, make sure you have Java 1.6.x installed on your machine: older versions (1.5.x) are known to give problems for the client.

Check the following FAQ for other issues you might encounter while using the Meetecho client.

 Let us know if this FAQ actually helped you or not: your feedback is important to help us improve the service!


  1. I can't login!
    Are username/password correct? Please beware that the site registration account and the Meetecho system account are different things, and you need a Meetecho system account to access the collaboration functionality. If you're sure about your credentials, make sure no firewall/proxy/ALG is in place to filter XMPP traffic.
  2. I don't see any video and/or my Participant controls are greyed out!
    This usually means the SIP call to enable the audio/video functionality didn't work for some reason. Make sure no firewall/proxy/ALG is in place to filter SIP/RTP traffic, e.g. by your router and/or provider. Specifically, make sure incoming SIP messages are not blocked: in fact, we currently rely on a server-originated reINVITE to negotiate BFCP moderation (see RFC4583), and we noticed that in some environments the reINVITE is blocked and never reached the applications, thus invalidating the SIP session.

    If you're sure SIP is supposed to work, use a third-party softphone to access the multimedia functionality (i.e.,, where xxxxxxx is the room number), and take advantage of the Meetecho client for all the other features.
  3. I can see video, but can't hear anything!
    This may be a dumb question, but does audio work for the other (Java) applications? Well it's worth a shot!
  4. Other people can't hear/see me!
    Did you make an audio request using the Participant floor client panel? Moderation is involved for both audio and video, meaning you have to ask the system/chair for permission to participate to the mix. If you made the request and it got accepted, check your OS mixer in order to make sure the microphone is right enabled and being recorded.
