The System page contains system level settings for the conferencing server. One of the settings you can configure is the listening ports used by the conferencing server. By default the conferencing server listens on TCP Port 22, 23, 80, 443, 1270 and 37000.
Once a user is connected to a conference on a specific port, the conferencing client will terminate all attempts to connect to the conferencing server on the other TCP ports. The presenter may notice when multiple users participate in a conference, the users may connect to the conferencing server on different ports.
As an administrator you can control the listening ports for the conferencing server. This is done by editing the ports in the local ports field. If you make a change in this field, you must restart the e/pop web conference server service, or reboot the server, for the port changes to take affect.
