3230 to 3250 is the

standard firewall port range. It needs
to be configured according to your local
firewall settings.

NAT

Network Address Translation is used

when the Server is connected to a router
with NAT support. The default setting for
NAT is OFF.
If NAT is ON, the system will signal the
configured NAT address in place of its own
IP address within Q.931 and H.245.
If NAT is set to AUTO, the system will try
to determine whether the NAT address
or the real IP address should be used for
signaling. This is done to make it possible
to make calls to endpoints on the LAN as
well as WAN.

Fields with an orange asterisk next to them require
you to restart the service in order for them to become
effective if they have been changed.

Restart Service

Restart Service will terminate calls that are currently live (that is, the

calls will be ended and conferences will not be available for on demand playback).
Before restarting the Service, check if there are live conferences in progress in the
Live Conferences page or check the call status on the LCD panel of the unit. The Site
Settings page will also display a warning if calls are in progress. If you click on the
Restart Service button while calls are in progress, you will be asked to confirm if you
want to go ahead with the Restart.
