new field in configuration.xml to hold a longer username than was previously possible, but the previous field was also
retained (the previous field was retained to ensure you could log in to restore your configuration). After you
downgrade, the new field remains in the configuration file until you overwrite it with your 4.3 (or earlier) configuration
file. If you fail to restore your 4.3 (or earlier) configuration, the upgrade process does not subsequently recreate the
configuration file (which already has the new field) and so the usernames can become inconsistent.

To work around this limitation, follow the recommended backup and restore procedures when downgrading or
upgrading. When you downgrade, you must also restore your configuration to ensure that the configuration file

Transferring a Persistent Call can Result in Both Endpoints joining the Conference
When you transfer a persistent call from the active endpoint to another endpoint, the MCU redials the original
endpoint, maintaining the persistence on that call, and also joins the target endpoint to the conference without call
persistence. The transfer use case is not officially supported in this version.

Issues when Removing the CompactFlash™ During Operation
Removing the CompactFlash card while the MCU is in operation has been known to cause a restart.
Windows Media Player
Streaming a conference with Windows Media Player in multiple windows or tabs on the same browser will crash the
browser. This is a known issue with Windows Media Player. If you need to stream more than one conference
simultaneously, use a different player such as QuickTime or Real Player.

simultaneously, use a different player such as QuickTime or Real Player.
In addition, Windows Media Player 11 can display streams incorrectly when used as an embedded player with
browsers other than Internet Explorer. This is a known incompatibility. In some cases, setting the video size of the
main streaming video window (the Video size field in the Streaming page) to Large will correct the problem. To work
around this issue, you can use QuickTime or RealPlayer instead of WMP, or use Internet Explorer instead of your
normal browser.
