uses a NAT, you can enable NAT option to allow the Polycom® RSS™ 4000
to communicate with external networks. If "Enable NAT" is selected, the
external address for NAT usage must be configured. The calling party
outside the LAN will call the NAT address of your system, while local users
on your LAN will continue to use the LAN address.
When setting the IP address, only dots and numbers within the scope of
0-255 can be entered for the IP address, subnet mask and gateway address.
Please check that an entered address is valid, otherwise an error message box

Gatekeeper Settings
Click on "System Configuration" -> "Gatekeeper settings" in the navigation
bar to enter the gatekeeper settings page. This page is used to configure

connection, and there will be no need to use a cumbersome IP address.
Gatekeeper configuration items will be enabled when this box is checked.
Then set the parameters. The word "Registered" will appear next to the check

and take advantage of registration of identical system prefixes to enable
multiple Polycom® RSS™ 4000 devices to share recording resources or H.323
connections. When an endpoint calls an E.164 alias plus a play prefix or
recording prefix to connect with a Polycom® RSS™ 4000 device, the
Polycom® RSS™ 4000 can determine the H.323 connection request type. If
resources are not available, the RSS will send a busy message to the
requesting GK. The GK will in turn send the playback or record request to
