Platforms supported by EVO:

  • Windows 2000/XP
  • Linux
  • MAC OS X (PPC and Intel based)
 

EVO system software includes a Server named Panda, and a Client named Koala.

When you start EVO, Koala is downloaded to your desktop and runs on your machine.

Prerequisites

Joining an EVO Meeting

    Tip: If you have a problem joining an EVO meeting, you can test if EVO is down for everyone, or just for you by going to the "this EVO" page.

Set up the audio settings to match your system, and click on the Restart Audio button. Then click on the Current Meeting Tab to return to the previous view.

Click on the Audio button when you wish to speak, but be sure to click off when you are done to avoid feedback being broadcast by your system when the next speaker assumes the floor.

Note: A second GUI, the "web cam" GUI, will also be displayed:

It is recommended that you close this window, since using video during a normal meeting consumes too much bandwith.

The following GUI will be displayed:

You may want to change your Panda Server by selecting a new one from the pulldown menu and then clicking on the Connect Selected Panda button:

Mac users, please note:

For more detailed information, see: EVO_Telephone_Bridge.pdf.


Troubleshooting:

Note: Be sure to check the EVO FAQ page for the latest information.

If the VievoJRAT tool does not work for your installation, first be sure you have java release 1.5, or higher, and that your browser option points to javaws, typically located in /usr/java/bin/java.

If you are experience problems:

  1. Start the Java Console from your browser before you start to download the Koala client.
  2. At the point you begin experiencing a problem, contact the Help desk at: evosupport@vrvs.org.

    Be sure to attach the Koala.log.

Note: The Koala.log contains the output of the java console, and can be found in your home directory:

  • Windows: C:\Documents and Settings\username\.Koala\Koala.log
  • Linux and Mac OS X: /home/username/.Koala/Koala.log

Also see: How can I report bugs, comments, and other feedback?

'Unable to Launch' error message after downloading Koala?

It may be that you've had an automatic Sun javascript update, leaving you with a stale Koala in cache. To clear it:

  1. At a DOS prompt, enter: javaws -viewer
  2. Go to preference and remove all versions of the Koala in cache.
  3. Restart EVO.

Transmit problems?

Go to the AV Controls —> Audio panel —> Advanced

There you can lower your sampling rate (good for home broadband), adjust the silence suppression threshold, and toggle the auto gain control on or off.

If all else fails, try disabling the Transmit Silence Suppression altogether.

No microphone/outbound audio?

Go to the AV Controls —> Audio panel —> Playback device

Try testing each of the drivers to see which one corresponds to your microphone.

If/When it works, save the settings, so the next time you join a meeting it will use the selected driver.

If it still doesn't work, send the java console information to the help desk.

Panda Server Causing Problems?

To change Panda servers:

  1. Select: Koala --> Koala Monitoring

The following GUI will be displayed:

  1. Select a different server from the pulldown menu,
    then click on the Reconnect button.
