6. IPanel Network Setup for
Public Internet
• The IPanel is designed to videoconference over the public Internet. The initial setup may involve
your local IT (computer network) support person to configure your IP network parameters--
especially your network firewall and some internal IPanel settings.
• This will only have to be done once at initial system installation. Thereafter, the user will
simply call other videoconferencing systems using the IPanel address book.
• This decision tree flow chart covers all of the common network configuration conditions. Go to the
