When you use ConferenceRoom you have to add some specific information about your server and the server(s) you may be connecting to. This is done with the /as server command set.
ADD - Add a server profile.
DEL - Delete a server profile.
DISABLE - Disable the server so it can not connect to a specified server.
ENABLE - Enable the server to be configured and ready for connection.
LIST - List the target servers settings.
SET - Specific profile settings.
When used with just the SERVER it will give you a list of the currently defined servers.
Example:
/as help server <command>
